Better Know a Native

By Beet 2022 07 July

You are all well aware that I have been beating the Native Plants drum for some time now. Last year, I wrote a four-part series outlining the reasons for growing native plants. Now, with our Native Plant Nursery back up and running after last year’s water crisis, I thought I would begin introducing you to plants we grow. I am going to begin with ground covers and grasses.

 

Many folks are considering removing part or all of their traditional lawns, as the water situation in the valley evolves and concerns for conserving water grow. Growing native ground covers and native grasses can be a great choice if you are wanting a more drought tolerant, low (relatively) growing area of vegetation in your yard. While these natives will not tolerate the mowing and foot traffic of a conventional turf lawn, they will cover the space, outcompete weeds, and require much less irrigation. Remember that native plants have roots that reach many feet–typically six to fifteen feet–into the soil and therefore require much less irrigation, once established.

 

Currently we have two ground covers and two native grasses available in the nursery. The groundcovers are native Yarrow and native Self Heal. The grasses are Tufted Hairgrass and Blue Wild Rye. Here is a brief description of each.

    Tufted Hairgrass, Deschampsia cespitosa, is a native bunchgrass. It grows naturally in moist, high elevation sites; sandy or rocky shores; bogs & fens and requires medium water. It does best in part shade. The seeds are an important food for birds, and it is host to Skipper butterflies (Hesperiidae family). If you have an area that gets regular water, this is a grass you might consider.

 

   Blue Wild Rye, Elymus glaucus, is a cool season, tufted perennial bunchgrass. The loose to dense tufts have erect to somewhat nodding seedheads. The foliage is blue-green in color. Growing 3-6 feet, this decorative grass likes part shade, and will tolerate dry sites. It is a desirable species for use in erosion control. The attractive, blue-green foliage adds value to commercial landscaping projects. It is host to nine species of butterfly and moth.

 

   Yarrow, Achillea millefolium, is a tough, lacy gray-green evergreen perennial herb. It grows 2-3 feet tall, with white flowers. It fills spaces aggressively, to form a thick, weed- preventing mat. Bloom lasts from April into September. It does well in both full sun and part shade and is especially drought tolerant. Added benefits are that it is fire resistant, hosts 10 butterfly and moth species, and is of special value to native bees.

 

      Self Heal, Prunella vulgaris, is a vigorously spreading member of the mint family. This tough little native grows 6 inches to 2 feet tall and forms a lush green mat. It is topped with lovely purple flower stalks from May through September. It can be grown most anywhere, with a little extra water in very dry conditions. In very hot areas, give it a spot that is protected from the hot afternoon sun. Self Heal is a favorite of bumblebees and butterflies, both as a nectar and a host plant.

 

All of these plants and many more are for sale in our JCMGA nursery, on the SOREC Extension campus, 569 Hanley Road, Central Point. The nursery is open for sales on Wednesdays from 10 a.m. to noon through October, and by appointment. Contact Lynn at kunlynn52@gmail.com to schedule an appointment.   We also have seasonal pop-up sales, so be on the lookout for those.

 

 

Why native Plants?  Plant choice Matters!

Douglas Tallamy, author of Bringing Nature Home, Nature’s Best Hope, The Living Landscape, and The Nature of Oaks, is a professor of entomology and wildlife ecology at the University of Delaware. He has written widely about the importance of choosing native plants for our gardens and encourages us to demand more from our yards and gardens.

Instead of just planting for decorative or aesthetic reasons, we must choose plants that provide the following ecosystem services:  soil enrichment and stabilization, water filtration, food production for humans and wildlife, carbon sequestration, weather moderation, habitat, and pollinator support.

NATIVE PLANTS provide ALL these services, while non-native plants do not.

Baby birds MUST eat soft food – meaning caterpillars. Insects specialize when they lay their eggs. Caterpillars, the larvae of butterflies and moths, develop from eggs laid on plants that have co-evolved with their insect partners who use them for host plants. Specialization allows the larvae to safely eat the leaves of a plant that might be toxic to other insects.

When we plant non-native plants in our landscapes, we grow fewer caterpillars. Fewer caterpillars mean a reduction in the numbers of birds. Recent research indicates that there are almost 3 billion fewer breeding birds in North America compared to 45 years ago. This is a 30% decline. Our butterflies and moths MUST lay their eggs on native plants.  Their caterpillars need to feed on the NATIVE plants with which they co-evolved.  Without native plants, we have no butterflies and moths, and our birds have NO CATERPILLARS to feed their young.  Caterpillars also supply food for reptiles, amphibians and small mammals.  They are a major component of all our food webs.

Choosing native shrubs for your yard will help support our declining bird populations. Some examples of shrubs you might choose are California lilac, serviceberry, and huckleberry.  These shrubs host 93, 81, and 130 species of butterfly and moth, respectively.

California lilac (Ceanothus sp.) likes full sun, has glossy evergreen leaves and brilliant blue flowers that open in early spring.

Serviceberry (Amelanchier alnifolia) can grow to 15 feet in full sun but will tolerate partial shade. It can be pruned to a small tree or leave it to spread into a thicket. Deciduous, with fragrant flowers in May and dark blue berries, it provides important summer food and cover.

Huckleberry (Vaccinium ovatum) will need more water than the others and will tolerate more shade.  A beautiful, glossy evergreen shrub, it provides extra early blooms for bees, shiny, tasty blue-black berries for you and the birds, and makes a lovely base understory planting in a moist, shaded woodland garden.

Why native plants? Plant choice matters!

Part One of a four-part series

You may be aware of the nationwide movement to grow native plants in urban, suburban and rural landscapes. Why is choosing and growing native plants in our gardens important? Why should we care? Because, as gardeners, we have a responsibility to care for planetary and local ecosystem health.
Most of us are aware of the list of environmental problems facing our ecosystems and planet: water and soil pollution by pesticides and petrochemical run-off from streets, lawns and roads; seasonal changes in weather and climate; invasive species encroaching into wild lands; increased risks of fire and flood; a disastrous decrease in insects worldwide – particularly pollinators; and a precipitous decline in our North American birds. Monoculture in non-native lawns in America now covers more acreage than all our National Parks combined. Nature has been driven out.

I encourage all of you to invite nature back into your landscape. Traditionally, when planning a garden, we ask, what do we want to do in the garden, and what plants do we enjoy? These are important considerations, but today we need to ask more probing and important questions as well. Before you venture into your local nursery and buy the “eye candy” you see, ask yourself these questions: “Will this plant improve biodiversity and support our local ecosystem?” “How will this plant help save nature in MY yard and neighborhood?”

For instance, if you are looking for a small landscape tree that will be a centerpiece in your front yard, you might be tempted to plant a Crepe Myrtle – a flashy, (human) eye-catching Asian plant import.

They really are lovely. But you need to look beyond just the beauty of that organism to you, and consider what it offers in the way of ECOSYSTEM SERVICES. In other words, does this plant:

  • Enrich and stabilize soil;
  • Clean and manage water;
  • Produce food, for ourselves and wildlife;
  • Sequester carbon;
  • Moderate weather;
  • Provide habitat;
  • Support pollinators.

Native plants do all of these things and are uniquely adapted to our local environmental conditions. What is eye candy to you – like the crepe myrtle – may provide none of these services. Our native insects need to feed on native vegetation and our native birds need to feed on native insects.

You might choose instead a native chokecherry (Prunus virginiana), native hawthorn (Crataegus douglasii), or native mountain ash tree (Sorbus sp.), as that specimen tree for your yard. Each of these have beautiful blooms for bees and other pollinators in spring and all produce berries in the fall as winter food for adult birds. Most importantly, each hosts a large number of caterpillar species that are the critical food for nestling and fledgling birds. No caterpillars, no birds. These three, small, yard-sized trees host 240, 80, and 42 species of moth and butterfly respectively. When you choose a NATIVE plant, you are planting a living bird feeder and growing next year’s butterflies.
