Top Tips for Spring Ephemerals

Red Trillium - trillium erectum - stinking benjamin

Also known as Stinking Benjamin, the gorgeous Red Trillium (Trillium erectum) is attractive to early season pollinators, and makes a stunning addition to the shade garden.

1. Spring ephemerals are best planted in fall

Spring-blooming perennials, especially in the bare root form, are best planted in the fall. This gives the roots time to establish, and allows the plants a strong start the following spring. The resulting blooms will benefit early season pollinators, as well.

2. An important nectar source for early season pollinators

Woodland ephemerals bloom, undergo pollination, and produce seed, all during a small window of time between snowmelt and when the trees leaf-out. The spring sunlight warming the woodland floor causes the plants to bloom. At the same time, the warmth stirs pollinating insects into action. The availability of spring flowering natives ensures that early pollinators have the nectar they seek in the critical period when they first emerge to forage.

3. Leaves are the best mulch for woodland species

Don’t bother buying mulch at the store, these spring beauties prefer leaves. Woodland ephemerals love the rich humousy soil as created by an accumulation of leaf litter in a forest. The leafy mulch is home to insects that pollinate and help spread their seeds. Seed dispersal is usually fulfilled by ants which carry the seed only a few meters from the plant. Because the dispersal is so local (unlike seeds dispersed by birds or wind), habitat fragmentation is a threat to the survival of spring ephemerals. Once these plants disappear from a forest, they rarely return.

Bloodroot (Sanguinaria canadensis) is one of the earlier woodland ephemerals – blooming in April in the upper midwest. Unlike most ephemerals, the leaves of Bloodroot do Not go dormant – except in very droughty summers.

4. Plant them with other, later emerging, plants. The stem and leaves will die-back.

In the heat of summer, most spring ephemerals “die-back” and retreat underground into their roots, until next year. Plant with other later emerging perennials to succeed them when the season heats up.

Shootingstar (Dodecatheon meadia) is a prairie ephemeral. Plant it in full-to-partial sun along with other prairie natives.

5. A little sun is a good thing…

Ephemerals are best planted where they’ll receive at least some early spring sunlight – under trees or in a wooded area is ideal. The shady area between houses is also a good option. Plants which occupy an area that never receives sunlight – such as in the shade against the north side of a building – may emerge and bloom later, due to consistently cooler soils.
