Yucca glauca Soapweed



Qty

Soapweed Yucca is a member of the Agave family (Agavaceae).  Like Agaves, Yucca glauca (Soapweed) forms a clump of narrow, tough, blade-like pale green leaves that extend out from a central, woody, almost tree-like stalk.  These leaves are very sharp!  Older plants usually have multiple stalks and will form a large spiky clump. Members of this family are from tropical or very dry, hot areas so it is most unusual to have this native Yucca in a colder climate like the Upper Midwest.  

A plant will take many years to flower, and seeds will not be produced each.  It is dependant on pollination by various butterflies and moths. Our bare roots are 2 years old.

The Pollinator Program at The Xerces Society lists this plant as having special value to beneficial insects because it "provides Nesting Materials/Structure for Native Bees; A plant that native bees nest beneath, within, or harvest parts from to construct their nests."

Dormant bare root plants ship each year during optimal transplanting season: Fall (October) or Spring (April/May).

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.

Bare Roots:

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.

Potted Plants:

Trays of 38 plants and 3-packs 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. Plant cells are approximately 2” wide x 5” deep in the trays, and 2.5" wide x 3.5 deep in the 3-packs; ideal for deep-rooted natives. Full-color tags and planting instructions/care are included with each order.

*please note, we are a mail order nursery and have no retail facilities, but you may pick up your order if prior arrangements are made. Pick up orders are subject to *MN Sales Tax.

Shipping & Handling Charges
SEED$100.00 and under: $5.00
over $100.00: 5% of the total seed cost

BARE ROOT PLANTS$50.00 and under: $7.50
over $50.00: 15% of the total plant 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.

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.
