Trillium grandiflorum Large-flowered Trillium
* We are unable to ship PLANTS (bare root or potted) outside the contiguous US or to CA due to regulations.
The common name Wake Robin is less used today, but it no doubt referred to the early April and May bloom time, corresponding with the appearance of the Robin. Trilliums are members of the Lily family.
It can be difficult to grow from seed. We are quoting William Cullina of the New England Wildflower Society and his book Guide to Growing and Propagating Wildflowers: "Seed that is cleaned and sown immediately outdoors in late summer will send out a root the next spring and a long narrow cotyledon the spring after that. After a couple more years, the young plant should be large enough to plant in the garden."
Cullina gives this germination advice for genus Trillium: "Seeds germinate only after multiple cycles of warm and cold, typically 40 degrees, 70 degrees, 40, 70."
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 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.

We dig bare-root plants from our outdoor beds and ship them April-May and October. 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.

Trays (38 plants) leave our Midwest greenhouse based on species readiness (well-rooted for transit) and based on order date; shipping begins early-May and goes into June. Each of the 38 plant cells are 2” wide at top x 5” deep; ideal for deep-rooted natives. Full-color tags and planting instructions/care are included with each order.
Shipping & Handling ChargesSEED$100.00 and under: $5.00
over $100.00: 5% of the total seed cost

*MN State Sales Tax of 7.375% is applied for orders shipping to Minnesota only. Shipping & Handling Charges are also subject to the sales tax.
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.
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.
