In the interests of planting more compatible wildflowers, I bought some seed from Nancy Ondra, who has the Etsy shop Hayefield. Details of the seeds and how to plant them are below.
Deschampsia cespitosa, Tufted Hairgrass
- From Hayefield: “A clump-forming, cool-season grass with basal green leaves and taller stems (3 to 4 feet) carrying early-summer flowers that develop into a cloud of golden seedheads. The species is native to North America and parts of Eurasia. These seeds are from plants grown from seed from Mien Ruys’ garden in the Netherlands. Full sun to light shade. Perennial; Zones 4 to 9.”
- From Seedaholic: “Fully frost hardy, Deschampsia is able to withstand temperature down to minus 15ºC (5ºF). The plants are tolerant of a range of moisture as long as it is not waterlogged. They can be planted by the waterside, in a woodland setting, or as an accent in the perennial bed.
Grow in reasonably fertile, moisture retentive but well-drained soil in sun or partial shade. The plants perform best and flower most in cooler climates. In warmer climates, it needs semi-shade and moist conditions, otherwise flower production may be reduced.”.
- Sow seeds in spring with temps around 68°F, one seed per cell. Germination is in 4-6 weeks.
Parthenium integrifolium (Wild Quinine)
- From Hayefield: “Wild quinine produces clusters of white flowers from early or midsummer to late summer or early fall atop 3- to 4-foot-tall stems. Its leaves can take on shades of purple and gold in fall. This U.S. native is equally at home in a meadow or a perennial garden. Full sun to light shade. Perennial; Zones 4 to 8.”
- From Everwilde Farms: They do not like being moved, so sow seeds where they will stay. “Sow seeds in late fall or as soon as the soil can be worked in the spring. Plant just below the surface, lightly compacting the soil. Keep the soil consistently moist until germination. Do not attempt to move seedlings, since they resent having their roots disturbed. For spring planting, mix the seeds with moist sand and store in the refrigerator for 60 days before planting.”
- However, other sites such as Wildflower Farm suggest that it can be transplanted, and should be treated like Baptisia (except shallower). Since it has a taproot, I may have better success with direct-sowing.
Baptisia alba (White False Indigo)
- From Hayefield: “produces spiky clusters of white flowers in late spring to early summer, followed by gray-black seedpods. The open, branching plants typically reach 3 to 4 feet tall. U.S. native. Full sun. Perennial; zones 3 to 9.” Sow in winter .25″ deep in trays outside for spring germination.
Diervilla sessilifolia (Southern Bush Honeysuckle)
- From Hayefield: “a 3- to 5-foot-tall, deciduous shrub with small yellow flowers from early or midsummer into late summer, followed by reddish seed capsules. The showy orange-red fall foliage color of this U.S. native is another handsome feature. Full sun to light shade. Zones 5 to 8.”
- From Missouri Botanical Garden: “Plants will spread by underground stems to form colonies, but are not considered to be invasive. Prune as needed immediately after flowering. Garden Uses: Small hedge. Naturalize in woodland gardens or on slopes. Shrub borders. Foundations.
- Sow in flats outdoors in winter. Seeds are very small, so do not cover.
- Host for the caterpillars of the moth Hemaris diffinis (Snowberry Clearwing or Hummingbird Clearwing).
