Switch Grass: Colorful grass blades with drought tolerance too

Switch grass is a native American grass that offers dramatic color and form, making it a standout in any garden:

  • Mass Planting: This grass looks fantastic when massed or used as a focal point. It’s particularly effective in modern landscapes but fits well into naturalistic gardens too.
  • Seasonal Interest: With its vibrant mid-summer and fall colors, switch grass provides interest when many other plants are fading. I have noticed many of the newer varieties of switch grass blades color up even by mid June depending on how hot it has been.
  • Water Needs: Once established, switch grass is very low water. However, it’s crucial to plant it in well-drained soil. Avoid areas where water can puddle, as this will cause the roots to rot. If you still have powerful overhead sprinkler spray be aware the water spray can cause these grasses to fall over.  Drip irrigation is better for this reason and that it is easier to water deeply and infrequently which is a perfect fit for this grass.
  • Height Considerations:
  • Stick with grasses under 4′ tall for low maintenance.  I always use shorter cultivars 36 to 44 inches tall to avoid my clients having to add supports.  But, taller varieties (such as 6 or 7′ tall switch grass) can be so stunning if you’re willing to put a ring or other support around the plant in spring.  Piet Ouldalf, a famous garden designer uses heavy metal rings with feet (the ring was about 14” to 18”) around his 6′ tall ornamental grasses.  I found this video link on the web for a grass ring but wow these grasses in the video are huge and much wider than any of the tall grasses that I use.   I was in Piet’s garden back in 2001 and saw the supports he uses.  It made me laugh because I had thought when my tall grasses flopped that I was overwatering or doing something wrong but even the master uses supports for tall grasses.  If you are an adventurous gardener, willing to use supports, go for some of the tall varieties like 8′ foot tall Thundercloud Switch Grass.

Switch grass is a versatile and resilient choice, offering beauty and adaptability to various garden styles.  It doesn’t provide well for Willamette Valley native insects but it pairs beautifully with pollinator friendly plants like Blanket Flower, Salvias, Penstemons and more. It makes an orderly but loose effect with native pollinator friendly shrubs like Coyote Bush.

Creating a custom landscape design requires a deep understanding of plant behavior. As a landscape designer, my goal is to select plants that not only look beautiful but also thrive in your specific environment with minimal maintenance. Here’s how I can help:

  • Custom Designs: I tailor designs to fit your space and lifestyle and your eco consciousness.  I won’t proselytize but am happy to create plantings that feed our native insects.  Birds gotta eat too and what they eat are insects.  Or maybe we will only use a few native plants and use more non native plants that help bees and use less water all without cramping your style.  Whether you want a low-maintenance garden or are more interested in plants that require learning how to care for them… I’ll create a plan that works for you.
  • Knowledge and Experience: I understand how different plants grow and perform and what it takes to care for them.    Lets create a thriving and vibrant planting plan for your new landscape.
  • Personalized Advice: We’ll discuss what “low maintenance” actually means to you and design a garden that meets your expectations and provides the stunning visual appeal you expect from a landscape designer.

Creating Stunning Landscapes with Ornamental Grasses: Expert Tips from a Landscape Designer

Drought tolerant and colorful N.E. Portland front yard boasts ornamental grasses like Blue Fescue.

As a landscape designer, one of my favorite elements to incorporate into a garden is ornamental grasses. Not only do they provide year-round interest, but they are also incredibly low maintenance and many are drought-tolerant. Grasses visually tie the plants in the garden together and add a calming influence.

I’m excited to share some insights and tips on using grasses in Portland landscapes and how to keep them looking their best.  The grasses I am talking about today are available at most garden nurseries and are perfect for creating a striking, low-maintenance landscape.

Fescue Grass: Elegance in Blue

Festuca glauca – Blue fescue is a stunning choice for any landscape. It’s soft blue hued blades add a touch of elegance and contrast, especially when paired with vibrant perennials like sedums. (They work with so many low water plantings.)  Here are some important tips you need to keep your fescue looking its best:

  • Planting: Space them further apart than you might think – at least 24 to 30 inches. This allows them to grow and shine without overcrowding.  Low ground cover plants (under 5 inches) can be planted close by and creep right up to the grass.
  • Maintenance: Mostly, you’ll just need to comb out the dead foliage in the spring with the occasional spruce up as needed.  When they get too big or start getting floppy, split them (very few people do this anymore), or just replace them entirely. They typically look great for about 3 -5 years assuming you didn’t overwater or over fertilize them which can cause rapid growth. I’ve never fertilized mine.
  • Water Needs: Once established, fescue has low water needs.  Figure out how you will water this area much less than other areas of your landscape.  If you can’t cut back the water using your irrigation system without damaging other plantings, try re configuring your overhead spray irrigation or close off the section of drip tube by replacing it with tube that has no holes in it.  (The term ‘established’ means the plant has been in one place for a full year or two.)
  • How to Kill this Plant:  Water it every day in the summer, over fertilize it, or plant it in a low place where winter water will puddle which will cause root rot.
  • Companion Plants: In this garden I used sedums, hens and chicks, and lower water perennials like Rudbeckia (black eyed susan) which are excellent companions.  The low sedums and succulents fill in around the grasses and add bursts of color. Other low water perennials such as colorful salvias, penstemons and blanket flower (Gaillardia) work well as do dwarf pines or other low water dwarf conifers.

Low Maintenance Reality

Even though you may need to replace fescue every 3-4 years, I still consider them low maintenance.  Sometimes I use fescue as a temporary planting, removing them once long term plantings such as dwarf evergreen shrubs have filled in and reached a more mature size.   Other times I deliberately use fescue for the long term vision with the client knowing they will be planning to replace them as needed.

Low Maintenance Ornamental Grasses for Your Portland Garden: Part 2 of 3

Low Maintenance Fountain Grass: The Steady Eddie of Ornamental Grasses In Your Portland Garden Design

Fountain grasses planted with late flowering Italian lavender create great textural contrast and cascade down this dry hot slope showing early fall color.

Fountain Grasses: Versatile, Vibrant and Low Water

Fountain grasses are popular for a reason – their graceful, often arching foliage and feathery plumes add movement and texture to any garden. They work beautifully in both formal and informal settings and look great with a variety of plants:

  • Commercial Appeal: Fountain grasses are often seen in commercial plantings, but don’t let that deter you. In residential gardens, they pair wonderfully with pollinator friendly naturalistic garden plants like heather, lavender, shrubs and many more pollinator friendly perennials that are stunning with fountain grasses.
  • Crowded Beds: When your planting composition starts to look crowded, it’s time to split or thin out some of the grasses. Many grasses including fountain grass need to be split every 5 years minimum.  If you overwater they may flop and they will need splitting sooner.  Splitting or thinning out some grass plants keeps the planting composition looking the way we designed it and avoids having the plantings grow into each other.  Crowding spoils the beauty of the different plants shapes and how their distinct shapes contrast with each other. I praise the faster growth of grasses over shrubs.  Using grasses means we don’t have to wait 5 years or more for the planting scheme to come together.
  • Versatility: Fountain grasses can fit into various garden styles, from modern to cottage. They’re also a great choice for adding height and interest. Last of all they can be used as temporary plantings while waiting for trees and shrubs to mature.

    Drought Tolerant Planting:  This plant handles lots of sun, and heat in Portland.  Once established most fountain grasses will take plenty of heat with a minimal amount of water.  These past two summers we have had high temps for longer periods than usual so the grasses next to concrete may need occasional deep watering to prevent scorched leaves.

Remember, even commonly used plants can create stunning effects when thoughtfully paired and integrated into your landscape.  Commercial plantings typically use one kind of plant en masse which is often kind of boring and doesn’t provide the diversity our pollinators need.  Pairing fountain grass with dark red hens and chicks and drought tolerant heather (like Calluna vulgaris ‘Mrs Ron Gray’)  is an eye catching combination.

Problems with Fountain grass are similar to fescue, overwater, fertilize, or plant in a heavy clay soil that is soaking wet in winter.  Dog pee can brown out sections of fountain grass.  This urine damaged section often dies out and it doesn’t recover.  I never set them close to the public sidewalk in city front yards with lots of dog walkers.  Some neighborhoods have a lot more dog traffic than others.

Privacy Screening Landscape Design for Kerns Neighborhood Portland: Part 2

Portland Plant Tips In Kern Neighborhood Residential Landscape Design

Plant tips for Kern Neighborhood residential landscape design.

In Part 1, I dropped by my clients Chris and Veronica’s Kern neighborhood back yard to get my eyes on their privacy tree, a Japanese elm called City Sprite planted 3 years ago by Landscape Design in a Day. It was doing beautifully but my clients had concerns that a talk with Honl Tree Care addressed. My visit also included some tips for the rest of the plants in their landscape design.

Kern neighborhood residential landscape design update.

Plant Health Care Tips

While I was there, I enjoyed seeing how much all the plants were filling in and checked on a few plants Veronica wanted advice about:

  1. Weed Prevention – To control the seeding on our native Heuchera and Fringecup perennials, cut back the flowering stalk before it goes to seed.  These two perennials provide food for bumble bees and many other important pollinators.  Also be sure to do this with the non-native Lady’s Mantle.  I like to pick the flowers of Ladys Mantle ( Alchemilla mollis) so yes please leave the flower on for the bees but be sure to deadhead it before it goes to seed and spreads.
  2. Re think and edit the plantings under the elm. A few plants are not getting enough sun now that our tree has gotten so much bigger.  The culinary purple sage needs a sunnier spot and could even go in a big pot and be moved.  I don’t see a good spot in the other planting beds for it so I would go for the pot approach.
  3. Shade plant tips for Kern neighborhood landscape design.

    Hardy Fuchsia thrives under privacy tree.

    The summer flowering Daphne and the hardy fuchsia near the purple sage look fantastic and can stay. The mass of Crocosmia we kept from the old garden is getting so big it is a little out of proportion.  You can always thin the Crocosmia.  Split the plant mass and remove the stalks in the middle as they are the oldest ones. Or maybe you are enjoying that very low maintenance plant as a large mass.

  4. Here is something to deal with soon.  The root weevil population is increasing. See my blog for no chemical advice on lowering their numbers.  They sure spoil the look of many part shade plants.

    Hosta Halcyon is slug resistant but root weevil re notching leaves spoiling the plants appearance.

  5. Your fun stepable groundcover that softens the edges of the big architectural slabs, Cushion Bolax, can be trimmed once a year or more to prevent it from growing over and minimizing our large pavers. Why trim it off the pavers?   Because the large pavers shape adds an attractive architectural element to the landscape overall and if it gets covered with the groundcover, we lose the impact.   See initial blog post from 2021 with testimonial from clients Chris and Veronica.

Portland Backyard Privacy Screening for a Family’s Outdoor Room

Family Needs a Private Backyard Landscaped in Portland

2 Patios with privacy screen are loosely connected with flagstone stepping stones in Portland, Oregon.

Two patios – one stamped concrete and the other crushed rock – are loosely connected with flagstone stepping stones.

Kristen and Rob have lived in their home long enough to remember when privacy fences did not exist between the backyards. Rob specifically remembers the days when he felt like their backyard was much bigger because there were no definitive boundaries from tall wooden fences. Fast forward a couple decades and the situation has changed – it’s time to create a backyard that is a more private family hangout space.

Instantly Hide an Eyesore with a Landscape Privacy Screen

Goal number one is to create a privacy screen without the cost of replacing the entire fence. The neighbors window had a direct view into the family backyard and, more importantly, a new flood light that the neighbor installed was beaming into their backyard at all hours of the day and night.

Before: Hello Purple House!

Sometimes the solution to a privacy problem can be solved with plant material alone, but this one needed a quicker resolution. The client sketched out the tall wooden privacy screen that I happily incorporated into the design. See the photo below to see how much that helps! That is only the beginning of the solution, however. In order to truly feel like a private space, we must create layers.

Vines and Trees create Privacy and Shade

To create layers, we use plant material. This not only adds to the screening but it also creates something more beautiful for the eye to concentrate on instead of seeing the house. Look how the Japanese Maple in the foreground adds to the privacy and the layered plantings create a wonderful distraction.

The Japanese Maple, Acer palmatum, had to be just the right shape for the space. We purchased the tree as a single trunk with a high canopy. Over time, the tree will spread out to create a natural shade from the blasting afternoon sun. We discussed attaching a permanent structure to the garage to create that instant shade, but all parties agreed that in this case, the shade of a tree creates the type of atmosphere they want, even if they have to wait a couple years for it to bulk up.

Three climbing hydrangeas, Schizophragma hydrangeoides, will scramble up the back trellis. This is a dappled shade area, which is ideal for this plant.  Unfortunately, climbing hydrangeas are not the fastest grower, but if you’ve ever seen a full grown one, you know it is worth the wait, and the clients thought so too.

Hardscapes create different “Garden Rooms”

This family backyard features two seating areas, aka “Garden Rooms”. The main dining area is poured concrete with a flagstone-style stamped pattern. The secondary seating area is crushed rock, installed to allow drainage. The secondary area is designed as the tween hangout – slightly set apart from the main area.

Drainage Solutions including a Rain Garden

As usual in Portland backyards, drainage is an important consideration. Luckily, the clients hired one of the best contractors for attention to detail – Donna Burdick of D&J Landscape Contractors.  One disconnected downspout had to be moved, the crushed rock had to be installed correctly for extra drainage, and the poured concrete had to slope in just the right way to ensure the winter water moved away from the house.
