Colorful Four Season Plant for Portland Residential Landscape Designs

North Portland residential landscape design for year round colorColorful Four Season Plant for Portland Residential Landscape Designs

I like to use Nandina as a colorful four season plant for my Portland landscape designs.

Advantages

The foliage is colorful year around.

Very low maintenance plants if you know the cool pruning tip.

They are easy to prune successfully so you can keep them for years.

Nandina varieties fit multiple diverse needs in the landscape because they can be small (18″ to 24” tall) or up to 8 feet tall.

They thrive in half or full day sun.  Deer don’t typically eat them.

People prune it wrong and then it’s so ugly they remove them – this is so easy to avoid.

It’s not a successful shade plant and will look leggy and sparse in the shade.  They will look so bad they will be removed.

People think Nandina is drought tolerant and they don’t water it in the summer……….this ends badly.

Nandina (from China) doesn’t feed our native insects; therefore, overusing it limits food for our native bird population.  I like to select at least a few native plants for companions.

Is this plant overused? Some garden designers snub the Nandina plant because it is used in commercial landscapes. Nandina is useful to my Portland residential landscape design clients who want low maintenance landscapes.  With the right plant partners Nandina can sparkle in a home landscape.

Nandina domestica – Heavenly Bamboo (not related to Bamboo)

There is a variety of Nandina to fit every landscape:

  • 6 to 8 foot tall  ‘Moyers Red’ or 4 to 6 foot tall ‘Plum Passion’ dress and soften an expanse of fence, hide the hot tub or garbage area nicely
  • 2 to 4 foot tall ‘Sienna Sunrise’, ‘Moon Bay’ or ‘Firepower’ work well in foundation plantings and entry areas.

Use a tape measure on planting day, assume the size info on the plant tag is being modest and give your plant more room to grow.  Some varieties of Nandina will grow 3 to 4 feet wide.   To keep your Nandina from getting too wide, I suggest pruning out entire canes at the base of the plant once a year.  For varieties that are listed as 3 to 4 feet wide, plant it at least 30 inches off your path.

A new variety called ‘Blush’ is typically 24 inches tall and 18 inches wide. The evergreen leaves turn an intense claret red and hold their color for months, longer and redder than other Nandina. ‘Blush’ was designed for the southern United States where it is fully drought tolerant. In Portland, all varieties of  Nandina including ‘Blush’, requires irrigation in summer. Multiple articles on the net enthusiastically state ‘Blush’ is drought tolerant but they do not mean here in the NW.  In the high humidity of an Alabama summer I too am probably drought tolerant…..Mint Julep anyone?

I love to combine Nandina with textured or needled plants that contrast with the narrow Nandina leaves.  Dwarf conifers, (Pinus mugo ‘Sherwoods Compact’), heather  Erica carnea ‘Adrienne Duncan’ or ornamental grasses like  Opiopogon (black mondo grass)  work well.  NW native plants, like salal, sword fern and huckleberry give  contrast and good looks.  They also provide food for native insects and for our birds who must eat native insects for food.  Pairing Nandina with typical cottage garden plants disappoints my aesthetic; there isn’t enough leaf contrast.

How to prune Nandina

The key to success with Nandina is learning how to prune it which is all about thinning the multiple canes (or stems) of the shrub.  Read more in my next blog or check out this u tube video I found to get you started.

 

 

 

Modern Landscape Design Plants for Portland

Modern Landscape Design Plants for Portland

As a Portland landscape designer I enjoy helping clients who want modern landscape design plants.

While well crafted hardscape is the key element to a successful modern style landscape, plant selection and how they are used is critical.

Here are a few things I keep in mind.  Balanced plant repetition, contrasting textures and overall shapes of plants, full season interest plantings, and low maintenance plants.  Keep in mind that the typical plants for modern style are not great for wildlife because they lack diversity.  My designs consider the clients many unique interests. A modern style design can have wildlife friendly plants included.

Here are 10 plants that work well for modern landscape design and are fairly easy to find.

Portland Garden Designer’s Holiday Gift Ideas

Portland Garden Designer with Favorite Tilly Hat

Portland Garden Designer’s Gift Ideas

Here are my favorite items to give as gifts.  The Tilley hat, favorite therapeutic hand cream, inexpensive gloves, Garden Design Magazine, plants as gifts and pruning tools.

The Tilley Hat

You can buy a Tilley hat at REI, Bonnet in NW Portland at Bonnet or on line.  I love my summer (Hemp fabric) Tilley hat because whether it’s picking peaches or playing with my dog, my hat stays on, it’s easy to wash.  I am around a lot of dirt and it is still a cream color. It protects my face from the sun (is recommended by some dermatologists for that purpose) and it’s not too hot to wear in the summer.

Hand Care

Great Hand Care Product

My favorite hand care product is Evelyn and CrabTree  60 second fix for hands.  It has 2 products, the Ultra Moisturizing Hand Therapy and the 2nd product called Hand Recovery.  There are more heavy duty hand products out there but this one has a light fragrance and penetrates the skin.  It’s therapeutic.  I handle art supplies and  garden so I like a good hand product.  Andalou Naturals Hand Cream is also nice but doesn’t penetrate the skin nearly as well.

Gloves

I love having A LOT of gloves.  I’m a person who misplaces gloves and as a child I resented that nursery rhyme about the kittens who lost their mittens because clearly I was going to be one of those kittens.  I have 20 pairs of inexpensive work gloves.  Gloves are great stocking stuffers.

Portland Landscape Designer Loves Garden Design MagazineGarden Design Magazine

Garden Design magazine readers are garden enthusiasts! They love the full-length stories (some run 10 to 20 pages to include lots of glorious photography) on plants, gardens, and design ideas for you to put to use—all presented without ads.

There are no ads in Garden Design. Yes, you read that right—no ads.  Just 148 pages of beautiful gardens and plants delivered to you each quarter. These are more like books. I’ve given this magazine to gardening clients and they are over the moon and tend to subscribe on their own the next year.

Plants As Gifts

North Portland Garden Design Itoh PeonyNorth Portland Itoh Peony in Garden Design

Itoh Peonies are so popular this year (2017) that wholesale and retail sources sold out completely. The variety called ‘Cora Louise’ was the most popular and the first to be gone from retail and wholesale sources.   Why are Itoh Peonies special?

They are tough enough for low maintenance landscapes so they are not just for serious gardeners……..and serious gardeners have simply lost their minds over these beautiful and sturdy stemmed plants.  If you have a gardener in your life who loves big colorful flowers……..this gift will express your love for years. A gift certificate to a local retail nursery with a photo would do it. Expect to spend $125 to $150 for a 5 gallon plant.  Here are links to Portland Nursery gift card, Cornell Farm gift card and a video explaining more about Itoh Peonies.

Another popular plant for gardeners that you can buy in December are Hellebores and the big garden nurseries will have these for sale starting in December through March.  These are somewhat toxic so don’t leave them where small children or pets can get them.

Pruning Tools

Pruners –  I love Felco and Corona tools the best.  Cheaper but very lightweight pruners and clippers from Fiskar are popular too.  Here is a good one called PowerGear.  Felcos are for the gardener in your life.  I still love my #6 Felco hand pruner for smaller hands and think they fit most women better than a #2 Felco hand pruner.

Outdoor Pee Pad for Dog – A Landscape Designer’s Solution

Portland dog friendly landscape design pee proof lawnOutdoor Pee Pad for Dog – A Portland Landscape Designer’s Solution

I live on a floating home and when my dog has to go pee or poop, the parking lot is a long ways away.  My perfect solution to living on the river with a dog, is synthetic lawn on my small garden balcony.  I have the advantage over most people with a deck or balcony because we designed the house to have a small roof garden with real soil.  It was easy to add the synthetic lawn over the existing soil.  Not only was it easy, when my dog pees on her synthetic lawn, the rain rinses it into the soil so it doesn’t smell.  In the summer when there is no rain I rinse the grass using a garden hose.  As you can see Daizzie likes to lay on her grass so it is used for more than an outdoor pee pad.  I enjoy sitting out there with her or drinking coffee from my outdoor sofa.

When she poops on her synthetic lawn it is easy to pick up unless she has diarrhea and then I do need to rinse with my garden hose.  The dog poop always goes in the garbage because I don’t want to add nitrogen to the river, I mean come on, just because it’s dog poop doesn’t mean it isn’t raw sewage.

Portland Landscape Design dog pee lawnAnother solution is a raised bed for grass.  My client Sherry has small dogs and no lawn except for this tiny patch.  She just replaces the grass in her raised bed occasionally.

Portland is a city that is very dog friendly.  As a Portland landscape designer I have lots of wonderful opportunities to create dog friendly landscape designs.  I consider it one of my best job benefits.

Violet Blue Flowers in Your Summer Garden

Violet blue flowers in your summer garden

There is something magical about violet blue flowers in a summer garden. A mass of long flowering intense violet, purple or blue flowers to see from your summer chaise is a joy. Here is a plant that I use in my garden designs that is easy care and long flowering.

Blue False Indigo – Baptista Australis ‘Purple Smoke’ is a long lived perennial so it will live for decades in your landscape. I use it in my landscape designs because it is colorful, low maintenance, fully drought tolerant, and long blooming. It has attractive foliage and interesting seed pods for fall. Clients who want color and easy care would line up for this plant if they knew about it. It looks great with ornamental grasses and has a more naturalistic look since it is related to lupine, a classic native wildflower.

Planting combinations for Portland Landscape Designs

I’ve used it in a low water parking strip in NE Portland with true dwarf pine, succulents like Sedum spurium ‘Green Mantle’, heather and black mondo grass.  In a SW Portland Landscape design I placed it to tower over a low boulder with plant companion ‘Kim’s Knee Hi’ Echinacea to the side.

Over time the plant will increase to a nice thick stand of charcoal green stems (which add to the beauty) and violet blue flower stalks.  ‘Purple Smoke’ is grown locally, other varieties and flower colors are only available by mail order.  I only use the  variety of Baptista Australis called ‘Purple Smoke’.  Don’t use the parent plant of  ‘Purple Smoke’, it is called just plain old Baptista Australis and gets too tall for most city gardens.

Plant uses

The primary use is ornamental and wildlife friendly. It’s not edible although it is a legume but it is not toxic. It’s a true native American plant.  North American Indians had many uses for this plant.  The Cherokee made a blue dye for fabric from the flowers.  The Osage made some kind of eye wash.  Others used the roots as an antiseptic for wounds.  It is not considered edible and was once thought to be highly toxic.  Modern research has changed this perception.  Read more about the plants chemistry.

How to kill Baptista: Water it every day in the summer and fertilize it heavily. Plant it in a low spot where winter rain water will puddle or sit.

Best practice:  Water deeply once a week the first summer.  The second summer water deeply but infrequently or put a plug in the drip emitter because it won’t need any water by the third summer.  I always place it with low water plants so it is easy to provide it with low water to no water. Don’t divide it. It has a tap root so dividing will kill the plant. If the clump gets too wide, take off new plants at the edge of the clump.

After the foliage yellows in the fall cut it down to the ground.  Mulch twice a year with garden compost.
