Portland Landscape Designer loves purple flowers of Monkshood

Portland landscape designer loves purple flowers of Monkshood.  My clients have unique likes and dislikes when it comes to plants.  When they love something specific, like purple flowers, one of my favorites is purple flowered Monkshood.  Other clients are focused on a purpose such as native plants or the lowest of low maintenance plants and not on specific colors.  My job is to find the plant palette that satisfies each client’s needs.

Purple flowers

I love tall columns of  purple flowers in my Portland landscape designs.  I often use them at the back of  planting beds to break up a bare wall or visually soften a fence. It’s an easy care perennial plant with no pest problems. It flowers a long time, provides great contrast with bright green or gold foliage and adds drama to the garden scene.

I only use varieties that don’t flop.  There is no need to stake the plants if you select the right varieties and water correctly. Staking plants is a hassle and not low maintenance so I don’t use plants that require staking in my designs.

Here are the Monkshood varieties I use in my Portland landscape designer practice.

Monkshood was used for poisoned arrows

This plant has a checkered past.  In medieval times Monkshood was also called Wolfbane and was the source for poisoned arrows.  Applied to a cut, Monkshood can be deadly and all parts of the plant are toxic.  Yet in modern times it is commonly used by florists and sold by garden centers and nurseries.  In 25 years I have no first hand knowledge of anyone being poisoned by monkshood but I don’t use it in my Portland landscape designs for young families or in parking strips.

How to kill this plant: 

Plant it in full sun and never water it, (or just as bad) water every day in the summer.  Plant in a low place where winter water will soak the roots for days at a time.

Best practice:

Most resources say part shade but I have found they thrive in half day sun to nearly full day sun with a few hours of dappled or light shade. Deeply irrigate Monkshood in full sun and less in part shade.  In time most Monkshood will become low water needs.   In too much shade it will flop and will not have as many flowers. Plant in well-draining soil, water established plants deeply once a week.  Don’t fertilize beyond adding a  compost or mulch around the crown twice a year.  Fertilizer may cause the plant to grow too lushly and make the stems flop. Cut it back to the ground in winter or when the leaves have gone yellow.  Learning how to water properly  creates confidence and makes maintaining your landscape less stressful.

Coreopsis colorful easy low-water plantings

As a Portland landscape designer I use Coreopsis verticillata and its’ cultivars because it’s a perfect colorful, low maintenance plant for modern landscape designs, bee friendly gardens, cottage gardens, container gardens and low-water plantings.

Clients love it because it flowers for such a long time from summer into fall.  Coreopsis is beloved.

I wrote this blog to help clients understand which Coreopsis will live for years and which ones will not.   Coreopsis verticillata is one of about five species of Coreopsis that are native to the United States.   Many people feel  that Coreopsis verticillata will grow too wide after about five years and will need to be divided.  A lot of my younger clients are so focused on low-maintenance plants that I typically don’t include any plants that need to be divided in their plans.  I still have this old-fashioned idea that I can provide a planting plan where all the plants will last 20 years and the trees forever.   However, if I really stick to that I’m shorting my busy young clients of some plants that are going to do very well for a long enough period of time. Digging up a plant every five years chopping it in half, tossing half of it or giving it away, and then re-planting half of it is less work than having  to buy a new plant.

So if you are still interested in a low maintenance easy plant that has to be divided read on.

Bee friendly flower

Coreopsis verticillata ‘Moonbeam’ is perfect for a bee friendly garden.

Another asset, Coreopsis verticillata hits its color stride after all the May and June flowers have faded in the heat.  I am still picking flowers for my bathroom posy in late September.  It’s a perfect fit for a bee friendly garden. You could start your bee feeding year with winter flowering heather, then Spanish lavender then English lavender and finish the year with Coreopsis.

I personally use Coreopsis in small bathroom bouquets. I love it’s ferny foliage texture and the strong zap of color.  But it’s a great addition to any flower arrangement.  They are so cheerful.

Here are some trustworthy choices easily available at most nurseries.

Coreopsis verticillata varieties

‘Creme Brule’ versus ‘Moonbeam’

When ‘Moonbeam’ came out in the 1990’s it was possibly the most popular perennial of all times. Nurseries could not keep it in stock. It has dark green ferny foliage while ‘Creme Brule’  has a bright emerald green ferny foliage. ‘Creme Brule’ is taller and has a soft yellow flower which is larger than ‘Moonbeam’.  The stems are stronger as well but while many claim that ‘Creme Brule’ is more mildew resistant, I have not found this to be true.   ‘Creme Brule’ tends to have flowers from the lower stems to the top which I find attractive. ‘Moonbeam’ tends to carry the flowers only at the top of the plant. ‘Moonbeam’ will be a little cheaper as it’s been around longer in the nurseries then ‘Creme Brule’. They are both great plants.

‘Zagreb’: is named for the capital of Croatia.  When you think of the trouble those people have been through and have persevered it makes sense that this plant carries that name. This plant is incredibly yellow and tough. I don’t typically recommend it because I have had problems with it reseeding and making a nuisance of its’ self in some areas.  I use it for incredibly difficult environments where having it spread won’t matter. Obviously, this would not work for small city landscapes except as a low maintenance mass planting.

‘Bengal Tiger’: select this plant for the amazing color contrast of red and gold. It is similar to a plant called ‘Route 66’.  The flowers on ‘Bengal Tiger’ will be more consistent whereas the flowers on ‘Route 66’ will be very different from each other on the same plant which some people feel looks a little muddy.

How to care for Coreopsis Verticillata

Plant in a well draining soil or up on a berm.  I’ve seen this plant do well at the edge of a lawn too.  To keep it flowering cut the plant back by half in mid summer. I have cut back ‘Moonbeam’ Coreopsis up to 3 times in one summer to keep it flowering until fall.

How to kill a Coreopsis

To kill this plant, plant it in a low spot with heavy mucky clay and it will die or over water it.  It comes back in the late spring so don’t be fooled and start to dig it up and kill it.  Be patient.  The dark green foliage is lacy and can be hard to see when the tiny shoots first emerge from the soil.

Companion plantings

I like to plant Coreopsis verticillata varieties with low water plants like Yucca ‘Golden Ribbon’, Caryopteris ‘Blue Mist’.  It’s a great texture complement to ornamental grasses like American Switch Grass, ‘Heavy Metal’ or Blue Oat Grass.  A mass planting of Coreopsis in the foreground with dwarf conifers and a  ‘Gilt Edge’ Silverberry shrub in the background is a very simple low maintenance plant composition.  For the cottage garden you can’t beat Coreopsis ‘Moonbeam’ with Nepeta cat mint and shrub roses like ‘Happy Chappy’ or David Austin rose ‘Graham Thomas’.

There are a lot of different species of Coreopsis out there and it’s buyer beware.  You have to pay attention to the names of the plants because there are some Coreopsis that make a nuisance of themselves and will seed all over your yard.   Many Coreopsis varieties are short lived so I tend to stick with these five. My Portland garden design clients love this plant for low maintenance, low water, and color in the summer landscape.

Tempting Red Hellebore Flowers for Winter Cheer

Popular Double Hellebore From Englands Ashwood Ashwood Garden Hybrids

Helleborus x hybridus ‘Ashwood Double BiColor Shades’ grown here in the NW by Monrovia.

Tempting Red Hellebore Flowers for Winter Cheer

Red flowered Hellebores are still the holy grail for plant geeks but they are so tough that anyone can covet these and grow them.

‘Peppermint Ice’, ‘Amethyst Gem’ and ‘Ashwood Double Bi Color Shades’ are Hellebore cultivated varieties with red to eggplant hued double flowers.  They wow us in late winter with a long vibrant flower display.

As a Portland landscape designer I like to use Hellebore in my designs.  The Helleborus x hybridus plants (which is what we are focusing on today)  can live for a hundred years, deer don’t like them, they are low water and except for a typically minor problem with aphids, and a little slug activity they are pretty pest free.  The leaves are leathery, attractive and provide interesting contrast with a range of plant material to include feathery fern fronds, ornamental grass or tiny leafed boxwood.

Helleborus x Hybridus 'Peppermint Ice'

Peppermint Ice has a darker outline around each of the petals. Its adds a lighter touch with pink red flowers.

They are shade tolerant although I  tend to use these three in strong morning sun with dappled or full afternoon shade.

Amythest Gem comes from the famous NW Garden Nursery. Double petals with a light edge gives us drama and the constrast needed to appreciate the mass of petals.

Double flowers give us more color than the singles but the singles, with only 5 to 7 petals, are also stunning and low maintenance.  ‘Ashwood Double BiColor Shades’ have a wine red petal with a darker edge which is opposite of ‘Amethyst Gem’.

Using Hellebore as a cut flower

The flowers last a long time in the landscape but not long as a cut flower because the stems wither quickly.  Most people cut the stems off and float them in a bowl.  I’ve picked them from my NW Portland garden, knowing they would only look good for a few days.  There are techniques for making them last which involve picking them at the right time based on the age of the flower and using an alcohol solution in the vase.  Follow this link  to NW Garden Nursery and read the bottom of their culture sheet.   Now that you are bringing the flowers inside please be aware that all parts of the plant are toxic.

All Hellebore flowers tend to nod down rather than face up.  This protects the flowers from cold damage (disfigurement/freezer burn) because water drips off the flower and  is not trapped inside. Nature designed this plant to flower in winter.

What about aphids?

What about aphids?  My only problem with Hellebore is aphids. Some years I don’t have any noticeable aphid activity. When I do it’s so early in the year that handy predators like lacewing and lady bug are still in sleep mode or haven’t hatched yet so I’m  on my own. Dealing with them is easy.  Use a spray bottle filled with water or 1 tsp of dish soap to 1 gallon of water and spray down your plant.  Use your hose or this great gadget called the bug blaster  which you can buy at Portland Nursery. (I’ve got to get one this year to use in my veggie garden too.) Don’t use a pesticide because most of them will harm bees even if they are not present when you spray. Aphids have soft bodies and will be damaged by the force of the water or the soapy solution will invade their bodies and disable them. You will have to knock them down with water or soapy water once or twice a week to prevent the temporary cosmetic damage.   I’ve never lost a hellebore plant to anything let alone a virus but in recent years virus has spread from plant to plant by aphids.  It is only an issue for professional growers or collectors.

How to care for your Hellebore

How to care for your Hellebore:  I water once or twice a week its first summer and then once a week after that.  Drip irrigation would be best rather than overhead sprinklers because drip can water deep into the soil.  Established Hellebore become quite a low water needs plant and might be content with every ten days or less.  An application of mulch around the plant once or twice a year is a good practice.  If your soil is so good that they make seedlings, be aware they won’t have the same flower as your hybridized plant. I cut the old leaves off the plant in late winter so that the flowers are not visually diminished by the previous years worn foliage.

How to kill a Hellebore

Plant it in a low spot where winter rain will rot the roots. Over water it and fertilize it heavily.

Colorful Cape Fuchsia Makes Beautiful Summer Memories

Cracker Jack on Barnes Road roof garden

My cat loved to watch hummingbirds.

Hummingbirds love Cape Fuchsia for the nectar.  I love to use it in designs because it adds so much color, is easy to grow and the new varieties work well with modern and cottage garden styles.  This plant is a crowd pleaser and I use it frequently.

I planted my first Cape Fuchsia, Phygelius x rectus ‘Salmon Leap’  on my roof garden in Portland’s West Hills.  It was at 900 feet and we had snow every year even though I was 5 minutes away from downtown Portland.   The house was designed so that the third floor master suite had easy access to and a view of my roof garden.  It had a hot tub that was 20 feet from my bed, a big overstuffed outdoor sofa with an overhead cover and plenty of Cape Fuchsia!  In spite of the colder winters, the Cape Fuchsia (native to South Africa) never flagged or failed in the 12 years I lived there.  I loved my roof garden and the only family members who loved it more were the 4 leggeds, Barley,  Cee Cee and Cracker Jack.  One particular day everyone was curled up on the big overstuffed sofa.  I was reading and pets were napping.  All was peaceful.  I heard a strange whirring noise.  At first I didn’t see anything unusual.  Out of the corner of my eye I saw my pets’ heads were going up and then down and then up and then down, I looked up to see a small blur. What did I see?  What was happening?

Portland roof garden

My roof garden 2006.

We were witnessing a hummingbird mating ritual.  The male made a 90 foot oval flight pattern to within an inch of his intended.  She was steadfastly ignoring him and drinking nectar from my Cape Fuchsia.  There wasn’t even a flicker in his direction.  The buzzing sound was made by his high speed downward trajectory.  It abated on the way up.   It was mesmerizing.  It was one of those wonderful garden memories that I treasure.    Just us mammals all watching the entertainment together.

If you would like to have some close encounters with hummingbirds or you just love colorful plants, the Cape Fuchsia is the perfect addition to your garden.  The best hummingbird attractors are the older varieties because they flower in the most intense coral red shades.  My favorites are ‘Devils Tears’, ‘Salmon Leap’ and ‘African Queen’, but they are too big and a bit too rowdy for a small yard.

The new varieties are more compact and a little tidier in habit.  The flower colors are available in more traditional shades.  When these new colors first came on the market I was annoyed.  I felt like they had dumbed down a great plant by removing the coral shades…….but then I saw it wasn’t an either or.  I now had more choices and that is always a good thing for a garden designer.

If you love modern landscape design style but don’t want to give up color, these new Cape Fuchsia are perfect for you.

Here are 2 new varieties from Skagit Gardens:

Croftway purple prince cape fuchsia

Skagit Gardens’ Croftway Purple Prince is an intense magenta.

Phygelius Aequalis ‘Croftway Purple Prince’ has that intense magenta color.  I think it looks really good with Black Mondo Grass………Morticia Adams where are you now?  It glows in the evening light.  ‘Croftway Purple Prince’ is cold hardy for the Pacific Northwest and listed as zone 6 Yah!

Phygelius Aequalis ‘Croftway Yellow Sovereign’ is 18 to 24 inches tall by 24 inches wide.  Many soft yellow flowers burn in full sun but ‘Yellow Sovereign’ can take the heat.

Skagit Gardens’ Yellow Sovereign does not scorch in full sun.

Barbara Ashmun, Portland garden writer has a great article about Cape Fuchsia’s.

I don’t tend to use the older varieties of Cape Fuchsia in front yards as the winter appearance is a little ragged.  If you love this plant like I do, simply cut it to the ground in mid December for a tidy look.

Hummingbirds Favorite Summer Flower

Portland Garden Designer Loves Colorful Cape Fuchsia

Cape Fuchsia, Phygelius, is a colorful, low maintenance long blooming summer flower for the Pacific Northwest.  I use it in landscape designs for clients who love color and watching hummingbirds.  It’s a personal favorite of mine.

If you are a person who wants a very tidy landscape that looks perfect all year long, this is not your plant.  I consider this plant to be low maintenance.  The winter appearance is not tidy but clients who love the color and the show simply cut it to the ground in December.  It can spread some.  In the spring if the plant is taking more territory than you want, simply pull on the stem that is straying.  Pull it out of the ground and cut the root off near the mother plant.  It is very easy, I promise.  Give it lots of sun, decent soil and water the first year.  It will need less water the following year.  Some clients water it about once every two weeks.

By the way, there is nothing wrong with needing a calm and low maintenance landscape.  We are all unique and a plant that makes one person feel delight can make another person feel claustrophobic.  I notice clients who grew up in climates where plants tend to be sparser can feel uncomfortable with the full flush of plantings possible here.

Morris after back yard

Mass planting of strong plant colors and a path help to break up the lines of the pool.

The first time I used this plant was for Art and Linda in SW Portland.  They had a 1960’s swimming pool in the backyard that dominated.  It visually ate the backyard.  They wanted a cottage garden style with lots of color.  My design solution successfully put the pool in a subordinate position to the landscape.  I created some great paths and shapes for the planting beds that broke up the lines of the pool visually.  We needed masses of strong plant color in the backyard to offset the powerful aqua rectangle.   I’m not a big color wheel garden designer but colors like coral and salmon are opposite the wheel from aqua. The Cape Fuchsia flowers are perfect for this situation because they flower in these colors and they flower all summer, hitting their stride during hot weather.  My clients enjoy hanging out by the pool and are entertained by the antics of hummingbirds.  Hummingbirds are strongly attracted to the hot coral red tones of the Cape Fuchsia.

Morris before back yard

Art and Linda’s back yard needed some color to offset the aqua of the pool water.

My favorite planting combination for this design was Panicum Virgatum, American Switch Grass ‘Heavy Metal’ with the Phygelius x recta ‘Devils Tears’.   They are a perfect contrast combination! The Switch Grass blade is a fine silvery blue texture.  It contrasts with the Cape Fuchsia’s dark green leaf and hot colored tubular flowers.  The inside of the tube is a mellow lemon yellow but mostly the hummingbirds are the ones who see this.

If you research this plant on the internet, you may think Cape Fuchsia are not cold hardy here since they are native to South Africa.  Many plant authorities also say these plants need a lot of water.  I don’t agree.  I have grown them at 900 feet on a roof garden and only watered them every two weeks.  They were successful for 12 years and were still there when I moved.

I’m always advocating for low water use so planting Cape Fuchsia with American Switch Grass results in a very low water landscape pairing.

While I love the old fashioned varieties, the new varieties  are shorter and flower in softer more traditional colors.  This has made the Cape Fuchsia a more versatile plant that works well for small properties and containers.  The only drawback to the new varieties  is the softer colors.   When you select a softer color you lose some of the hummingbird magnet effect but you still get a great plant.  Check out other great hummingbird plants.
