Willapa Refuge’s Wild Lawn: First Spring

Kathleen Sayce, June 18, 2021

It’s been eight months since the wild lawn was planted at the new office for Willapa National Wildlife Refuge, and Pacifica irises bloomed in their first spring. I took a few photos when I visited the lawn in April and June, while Program Manager Jackie Ferrier photographed almost every iris that flowered. 

We expect a bigger display of flowers next year as the wild lawn settles in. 


A variety of Pacifica iris grow in the lawn, including I. douglasiana, I. tenax, and seedlings from PCI hybrids. The plan is to let all the plants set seed, and scatter the seed around in late summer. We will also be planting more areas in coming years as the blackberries and other woody shrubs are suppressed around the visitors center and staff offices. One annual fall mowing is planned. Without mowing, woody shrubs and trees would soon (very soon!) take over the entire area.

The grasses that provide a backdrop to the wildflowers are fescues, including Roemer’s and red fescue, and a low growing fescue mix. A combination of fescue plugs and seeds were used. This is important, because the grasses that grew here historically included reed canary grass, velvet grass and orchard grass, all too large and too dense for irises to thrive with them.

Other wildflowers include strawberry, springbank clover, yarrow, pearly everlasting and thrift. 


A new compost facility is selling compost by the truckload, so the next sections of the wild lawn will get a top dressing of compost to boost nutrient retention in winter, and water retention in summer. In these sections the compost will be tilled into the upper few inches. In the original section, we will top dress the lawn with an inch or so of compost next fall.

This location was formerly a cattle ranch homesite, and there are thousands of daffodils growing throughout the area. The daffodils were retained as legacy plants, and also put on a nice display last spring. 


This fall we will add more wildflowers, including shooting-stars, common camas, checkermallow, chocolate lily, blue-eyed grass, and of course, more irises. 


If anyone wants a plant list, please contact me by email and I will send you the plant-list-in-progress.
