Blooming species become few after the initial green-up of spring. Yellow Pimpernel provides delicate yellow umbels of flowers through the heat of early summer. It is a fine textured plant that smells of celery when crushed and prefers drier, woodland edges. Deer, at least in our area, mostly avoid it.

Rarely seen in cultivation, the flowers attract many small spring-flying insects and the leaves feed the caterpillars of the Black Swallowtail and Ozark Swallowtail, and should be used more often in the landscape if only for this purpose. Although this butterfly host plant prefers drier, woodland edge habitats, it will also do well in full sun and medium soil. 

Our website also features the following species with similar yellow umbel blooms, blooming late-spring or early-summer: Thaspium trifoliatum var. trifoliatum (Meadow Parsnip), Polytaenia nuttallii (Prairie Parsley) and Zizia aurea (Golden Alexanders).  

All of these important perennial native plants should not be confused with the similar-looking Pastinaca sativa (Wild Parsnip), a highly invasive Eurasian biennial commonly found on roadsides and other disturbed sites. Wild Parsnip is taller than the aforementioned natives, blooms later, and can cause painful skin burns.

2 Questions asked on Taenidia integerrima

Will yellow Pimpernel stand up right by it self, or will it need supporting plants, grasses around it, to help from leaning over like some Asters. Thank you.
Hi Chuck, I have seen this plant standing upright pretty well on its own, but I have also seen it leaning significantly. Dense plantings are always a pretty good way to combat that.
What criteria is used to determine pairing recommendations for a native plant? It appears that pairs are similar in structure or color, but I am curious about the other factors that make plants pair well. In particular I am looking for a recommendation that will help Lion's Foot and Yellow Pimpernel stand up on a sloped site. Both flop down hill.
Hi Carol. We typically select "Pair With" plants within the same genus, then by sun/soil conditions. We may be changing that heading to "You May Also Like," since it is more accurate for what we list there. As for species that will help prop up Yellow Pimpernel and Lion's Foot, take a look at slightly shorter plants, especially grasses and sedges. Side Oats Grama, Blue Grama, Path Rush, Little Bluestem, and Prairie Dropseed are all excellent "support" plants.

Seed

Growing your own plants from seed is the most economical way to add natives to your home. Before you get started, one of the most important things to know about the seeds of wild plants is that many have built-in dormancy mechanisms that prevent the seed from germinating. In nature, this prevents a population of plants from germinating all at once, before killing frosts, or in times of drought. To propagate native plants, a gardener must break this dormancy before seed will grow.

Each species is different, so be sure to check the GERMINATION CODE listed on the website, in the catalog, or on your seed packet. Then, follow the GERMINATION INSTRUCTIONS prior to planting. Some species don't need any pre-treatment to germinate, but some species have dormancy mechanisms that must be broken before the seed will germinate. Some dormancy can be broken in a few minutes, but some species take months or even years.

Seed dormancy can be broken artificially by prolonged refrigeration of damp seed in the process of cold/moist STRATIFICATION. A less complicated approach is to let nature handle the stratifying through a dormant seeding, sowing seeds on the surface of a weed-free site in late fall or winter. Tucked safely beneath the snow, seeds will be conditioned by weathering to make germination possible in subsequent growing seasons.

Dormant Bare Root Plants

We dig plants when they are dormant from our outdoor beds and ship them April-May and October. Some species go dormant in the summer and we can ship them July/August. We are among the few still employing this production method, which is labor intensive but plant-friendly. They arrive to you dormant, with little to no top-growth (bare-root), packed in peat moss. They should be planted as soon as possible. Unlike greenhouse-grown plants, bare-root plants can be planted during cold weather or anytime the soil is not frozen. A root photo is included with each species to illustrate the optimal depth and orientation. Planting instructions/care are also included with each order.

Potted Plants

3-packs and trays of 32, 38, or 50 plants leave our Midwest greenhouses based on species readiness (being well-rooted for transit) and order date; Spring shipping is typically early May through June, and Fall shipping is mid-August through September. Potted 3-packs and trays of 38 plugs are started from seed in the winter so are typically 3-4 months old when they ship. Trays of 32/50 plugs are usually overwintered so are 1 year old. Plant tray cells are approximately 2” wide x 5” deep in the trays of 38 and 50, and 2.5" wide x 3.5" deep in the 3-packs and trays of 32; ideal for deep-rooted natives. Full-color tags and planting & care instructions are included with each order.

Shipping Season

SEED, TOOLS and BOOKS are sent year-round. Most orders ship within a day or two upon receipt.

BARE ROOT PLANTS are shipped during optimal transplanting time: Spring (April-May) and Fall (Oct). Some ephemeral species are also available for summer shipping. Since our plants are field-grown, Nature sets the schedule each year as to when our season will begin and end. We fill all orders, on a first-come, first-serve basis, to the best of our ability depending on weather conditions beyond our control.

*We are unable to ship PLANTS outside the contiguous US or to California due to regulations.

Delivery

We ship using USPS, UPS and Spee Dee. UPS and Spee Dee are often used for expediting plant orders; they will not deliver to Post Office Box numbers, so please also include your street address if ordering plants.
