Ferns for Portland Landscape Designers

I’ve been following Judith Jones and her career as a fern expert extraordinary before social media existed.  She’s been my fern guru for 20 years and I’ve tried to catch her lectures when she comes to Portland at Joy Creek Nursery, HPSO plant sales and garden shows.  My favorite Judith sighting was at the Seattle Flower and Garden Show when her show garden as the set for the Flintstones.  She was dressed as Wilma complete with a bone in her hair.  There was a dozen or more 8’ tall tree ferns and a 20’ tall volcano.  It looked like a real tropical fern forest.  It’s still my favorite show garden of all times.  She and her nursery Fancy Fronds have been my source for ferns in my designs.

She gave a special program for ANLD Portland Landscape Designers the other evening. She has continued to evolve and had new plants for me to consider as well as highlighting my old favorites.   It was such a pleasure to see her and learn more about ferns for landscape designers.

Tracys Hybrid Maidenhair – Adiantum x Tracyi

Is it possible to have a new fern?  This maidenhair was discovered in the 1900’s instead of 2000 bc which makes it new in my book.  Tracyi is a natural cross between two California native deciduous Maidenhair ferns and oddly enough it is evergreen.  Clients like a plant with long seasonal interest. The leaf or pinnae is cute, it has little dimples in the edge of each leaf.  The plant is a foot tall and like many Maidenhair ferns, the texture of the plant is what people notice most.  The best place to buy it is Judith herself at www.fancyfrondsnursery.com   I will list it in the shade category but many maidenhair fern can take some sun and become low water plants over time.  Typically, they are listed for moist shade.

Peacock Moss Modern Landscape Style

Kraus’ Spikemoss – Selaginella Kraussiana is a low ground cover fern that is underused. Some think it isn’t cold hardy for Portland, Oregon. Not true! I have it growing outdoors in a container where it’s handled many winters. It’s thriving in boulder crevices up in Willamette Heights. Plant it where it will have good drainage and light shade.

Kraus’ Spikemoss – Selaginella kraussiana ‘Gold Tips’ 

My descriptive words for Spikemoss are baby chick fluffy, with evergreen piles of adorable pettable  texture.  Judith feels it is underused and recommends it for Portland designers.  Don’t get confused and purchase Peacock moss, Selaginella uncinata because they are devoured by slugs.  I’ve been using Spikemoss for years at garden shows to dress up my pottery which is how I know that the millennial generation loves it.  They come running into my booth to pet the moss and ask if it is real. Spikemosses are not true mosses and are classed with ferns because they have a vascular system and moss doesn’t.   I’ve used Spikemoss in between boulders and I love the effect. My advice for boulder plantings is plant twice as much as you need, use a mix of compost, clay and sphagnum moss in the crevices. Don’t plant them at the base of boulders; they won’t get enough light.  Where it succeeds, it is eye catching with chartreuse fluffy fans against gray boulders. It has succeeded planted under my  (containerized) Dwarf  Vine Maple for 6 years so cold isn’t an issue.

Narrow Planting Beds

Photo credit Fancy Fronds, Judith Jones Narrow fern fits urban gardens (Scaled Male Fern Dryopteris 'Stableri Crisped')

Scaled Male Fern – Dryopteris ‘Stableri Crisped’ – Grow this fern in front of a long fence to make the fence subordinate to the landscape instead of the most prominent feature.

Ferns for Narrow Planting Beds – Narrow Golden Scaled Male Fern-Dryopteris affinis ‘Stableri’ which has no crests and ‘Stableri Crisped’ which has curled and crimped pinnule margins.  Think amazing texture!   Judith suggests these for narrow planting strips in general and in front of tall fences in particular.  My experience is that builders and concrete contractors often create front walks that only leave a skinny strip for plants.

Imagine a  6′ tall fence with, you guessed it,  about 15” to plant in.   It’s a problem for homeowners and even designers struggle finding plants that fit this situation.  Jack hammering out the front walk and starting over with a new one is the best thing if there is space for other options and budget.  The rest of the time we find the right plant that will fit that location for years without our clients needing to do much.  Can you imagine a fern trimmed into a lollypop?  We are trying to avoid that sort of business!!  Sigh…….. These handsome ferns could live for decades in that narrow area as long as the soil drains reasonably well.  These ferns are also my favorite for visually making the fence subordinate instead of prominent. The narrow vase shape also makes them perfect contrast partners to plants with large leaves like Hosta or Fatsia in larger planting beds.

Foundation Plants

Sword Leaf Holly Fern – Polystichum xiphophylum  and Makinoi’s Holly Fern – Polystichum ‘Makinoi’  

These two ferns could become your new regular use plants in designs.  They are evergreen, not as tall as many ferns and look good in foundation plantings.  Place them in partly shaded and shady areas.

Olive colored foliage makes this fern unique for Portland Landscapes

Makinoi’s Holly Fern – Polystichum ‘Makinoi’

Sword Leafed Holly Fern – Polystichum xiphophylum is neat and small at 15″ tall.

Makinoi’s Holly Fern – Polystichum  ‘Makinoi’ –  Olive, straw gold and russet fern with lustrous fronds is beautifully different than other ferns. Judith says it like this: “There is a reptilian sheen to the olive-green linear-lanceolate fronds which blends subtly into the varied straw to chestnut colored scales cloaking the supporting framework.”   It’s typically a 2-footer and evergreen or ever olive.  Some filtered morning light is okay but this fern is not for sunny areas.

Shade Garden Combination of fern and hosta

ANLD Member Rick Hansen design Arachniodes Standishii – Upside Down Fern in 2015 Designers Garden Tour. Note the color echo achieved by matching the mid green of the fern with the mid green leaf edge of the hosta.  See the contrast from the ruffled texture of the fern with the smooth hosta leaf.

 

 

Big Drama Fern

Upside Down Fern – Arachniodes Standishii  –  It’s not an upside down plant but the way the little pinnae are organized is opposite of all the other Arachniodes ferns in the world.  What I  care about is that it is cold hardy here (native to Korea and Japan), has an over the top lacy pattern and is easy to grow.  It’s semi evergreen.  It can take a little direct morning sun, typically place it in filtered shade with some deeper afternoon shade.  Plant it in front of other plants for a peek through the lace curtain effect.  It can eventually get large (4′ tall and wide) and I am trying mine on the north side where it will get sun until noon in mid June.  I’m pushing my luck a bit so we will see if it scorches and if so how long it takes to recover.

After the lecture, I bought plants. Even in my near senior status I felt that good old plant lust rise to the surface.  I usually don’t indulge in buying plants at lectures.  Managing all aspects of my landscape design business doesn’t leave me a lot of time for my former hobby of gardener and plant enthusiast.  I must be careful that I don’t kill plant material purchased in a state of amnesia about the reality of my life.  I bought these 5 ferns:  Tracys Hybrid Maidenhair – Adiantum x traceyi, Narrow Golden Scaled Male Fern  Dryopteris x complexa ‘Stableri Crisped’, Arachniodes Standishii, Upside Down Fern, Makinoi’s Holly Fern – Polystichum  ‘Makinoi’, and have lost the tag on the last one.  It’s clearly a Holly fern of some kind.

Buy ferns from Judith

My clients and I buy ferns directly from Judith off her web site or via an email. I like buying from her and get loads of advice and information when I need it. They arrive in great shape and are mostly sized between a 4” plant and a quart.  If you want bigger sizes, contact her before the spring or fall HPSO plant sale and she can bring them down for you.  Your clients can buy directly from her too.

Dog friendly shade trees for small yards

digging dog small

On the hunt for a cool spot to lay.

It’s hot and dogs are smart.  They want shade and we can provide it or be warned, they may figure out something on their own.  A lot of dogs left to their own devices in a treeless yard will dig a hole under your nice big hydrangea or other shrub and lay in the cool earth in shade.  This may work out just fine for your pet but not your plant!

If you have a big yard you probably have at least one big tree so you have shade.  If you have a small landscape it gets trickier.

Small trees for full sun that provide shade:

Katsura Heronswood Globe

Katsura ‘Heronswood Globe’

 

 

Katsura H. Globe has medium sized heart shaped leaves and casts light shade. (Eventually 15′ – 20′.)  I’ve not seen it this big in the Pacific Northwest.

 

 

Lagerstromia natchez

Crape Myrtle ‘Natchez’

 

 

 

This Crape Mrytle has a thick leaf and can cast a heavy shade.  Beautiful flowers, bark and fall color make it a favorite.  (Eventually 20′ tall and wide.)  I’ve not seen it this big in the Pacific Northwest.

 

 

Strawberry tree

Arbutus Unedo ‘Compacta’

 

If you select Strawberry Tree Arbutus Unendo ‘Compacta’ be sure to purchase the compact variety.  It is my top choice for heavy cooling shade for a small yard.  I’ve seen this as a 15’x15′ vase shaped tree after ten years.  Please note, too much summer water will kill this durable evergreen.

 

blog Hydrangea phantom at Normas

Tree form Hydrangea Paniculata

 

 

This large shrub/small tree has large leaves and is great for dog shade.  This plant is in Norma B.’s landscape.  It was planted in 2013.  It can be a 15’x15′ tree but typically is kept 10’x10′ with pruning.

 

 

Five Important Garden Tips

Five Important Garden Tips You Need

Treating blackberry and ivy with Roundup in the spring and early summer is pretty much useless.  There is a time when these plants are most susceptible to herbicide. It’s a million times more effective in late summer and early fall.   In an ideal world we would not use herbicides at all, if you are going to use them you want to use them sparingly and at a time when they will be effective.  For information on how to do it right see my blog:  Treating blackberry and ivy .

Over watering or under watering new plant material.  Your common sense will kill your plants if you don’t have the specific information for the specific plant type.  You can’t water a new tree the same way you would water your petunias.  I insist my garden coach clients have a written watering plan for the first two years of their new landscape.  I tell them how long to water and to hand check the soil to see if their efforts are successful.  Last, but not least, if you’re watering every day you are in line for losing a lot of new plant material.

Plant labels lie.  Trust me it’s not a conspiracy, but they write the label so that it makes  sense for the entire country.  In the Northwest we have the ideal growing conditions so plants will grow taller and wider than indicated.  In addition, just because a plants’ mature size is 15’ tall, does not mean it will stop growing once it gets there.

Light.  Labels don’t have enough room to explain the complexities of sunlight, let alone the four different kinds of shade.    Great Plant Picks is a great information resource in many ways, and has an excellent explanation about the different kinds of shade.   There is no perfect solution, even checking the Web will get you four different suggestions for light requirements on a single plant.  This is why experienced gardeners often move plants that don’t seem to thrive in the first location they select.  Others hire designers who know these things first hand.

“Thank you so much for all your information today and your helpful phone call Saturday.  I was pulling out plants in my mind as I was going to sleep last night.  I can’t wait to get started!”  D’Anne Oneill

Pruning.  My best advice is don’t let your father-in-law prune your Japanese Maple!  Do not do hedge pruning on plants that are not hedges.  You need to learn how to do a thinning style of pruning. While I certainly advocate for hiring a garden coach (since I am one) you can learn from a local nursery, community college or someone who has trees and shrubs that don’t have a bunch of stubs on them.  We want pruning that will enhance a plant’s natural and unique shape.

Oregonian Home and Garden blog features Carol Lindsay, Design in a Day Video

Hi here is my recent exposure in the Oregonian’s Home and Garden blog by Kym Pokorny.  This blog gives me credit for starting the Design in a Day way of doing landscape design oh so many years ago and has an amazing photo of me with the amazing Barley Dog.

carol.jpgView full sizeCourtesy of Carol Lindsay  Designer Carol Lindsay and her late dog Barley.

Longtime Portland garden designer Carol Lindsay was one of the first to implement the idea of Landscape Design in a Day, which would be why she named her business that. The concept is a four-hour consultation with Carol, who will listen to your needs and wants and then come up with a do-it-yourself design. She also offers garden coaching and full-scale garden design.

In checking out her website recently, my eyes spied three topics, probably because Carol and I share a love of dogs. Her sweet, adorable cocker spaniel Barley sadly passed away this year. He will always be remembered.

Her dog-related posts include:

Dog-pee-proof plants.   Synthectic lawns and dogs: Do they go together?

Dog-friendly landscapes.

But the big news is a video Carol made for About.com about rocks walls.

Rock Garden Video

As an example, she uses one that she designed 10 years ago with small plants such as heathers, ferns, dwarf ornamental grasses and ground covers.

“We started out with 10 or 20 little 4-inch speciality ferns,” Carol says on the video. Over a 10-year period of time, these little ferns crossed with each other and created all these little sporelings … Out of those 20 little ferns that we bought 10 years ago, there are 100 ferns here now, if not more than that.”

“It’s high interest, easy to care for and beautiful to look at.”

Treatment for Blackberry and Ivy – How To Get Rid Of It

Garden Tips for getting rid of Plant Invaders

The best time of year to treat blackberries and English ivy is coming right up…..so prepare now!

Blackberry Fruit

How can anything so sweet, be so evil?

Plan to treat invasive blackberry in September and early October. The reason for the specific timing is this: only in the fall will the plants pull an herbicide to the roots, thereby killing the entire plant. The rest of the year treatments are only partially effective. For greener garden practices that use less chemicals treat the plants only in the fall, and water your bad old blackberries well prior to treatment. In fact you could even fertilize them and pamper them for about two weeks…….and then treat the with an herbicide.

My long time client Pat Tangeman  is clearing a large area of her property . She bulldozed last winter and got rid of a decades old blackberry wilderness that had an extensive root system with many large stumps. However, even a bulldozer didn’t kill all the blackberries! Many came back this spring so she called me to problem shoot and design a planting plan for the area.

The result:
This fall she will treat her remaining blackberries and will allow the herbicide to trans-locate to the roots to truly kill the plant. Then she will have the remainder of large roots dug out. Once this is done she can plant the new garden we designed together. Victory over the blackberry!
Another client in the Dunthorpe area is having her English ivy treated by professionals the first of September. She is utilizing the same techniques by doing the pre-watering and pampering herself. Once the invasive plants are dead we will be ready to place her new garden plants from her garden planting plan.

Not sure still when would be a good time? Need a professional hands on approach to help get you started? There are still a few appointments for Garden Coaching open in September and October. Winter is also a great time for making plans so you can have what you want instead of taking your precious time to care for a layout and plants you don’t like.
