Some might find Gaura to be too tall, flimsy, or "weedy-looking," giving a planting an untidy appearance, but Biennial Gaura establishes in a prairie planting early like Black-eyed Susans, giving the area much-deserved color in year two and blooming in the somewhat dreary month of September.  First-year rosettes will appear easily from seed, and the plant will put on 4-6' in its second year.  The numerous late-season flowers atop each stem are usually light pink but can take on almost a pure white or deep reddish-pink color.  Four petals and eight yellow stamens make up each flower. 
 
Although a single plant will only persist for 2 years (biennial), the fragile stems on this tall plant will sway with even a gentle breeze, helping it distribute its seeds readily, ensuring the species persists in a planting.  It is an important native plant for pollinating long-tongue bees and bumblebees. The larvae from the Gaura Moth and Primrose Moth will feed on the leaves and seeds. This plant should not be overlooked when planning a prairie.

It is best planted with other tall plants as individuals can seem a bit ungainly in appearance. It also self-seeds readily, so competition with other plants can help keep it in check.
 
Large-flowered Gaura, a closely-related species, appears more in Southern states but does not have larger flowers as the name suggests.  The only distinguishing feature is that Large-flowered Gaura has curled hairs lying against the stem instead of hairs that stick out on the stem, as on Biennial Gaura. Biennial Gaura is also known as Oenothera gaura and Biennial Beeblossom.

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 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 (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.

*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 and POTTED PLANTS $50.00 and under: $7.50
over $50.00: 15% of the total plant cost

TOOLS and BOOKS have the shipping fee included in the cost of the product (within the contiguous US).

**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.

POTTED PLANTS (trays of 38) typically begin shipping early-May, based on order date and when all the species in the tray are transit-ready. We are a Midwest greenhouse and due to the challenges of getting all the species in the Mix & Match and Garden Kits transit-ready at the same time, we typically can’t ship before early-May.

*We are unable to ship PLANTS (bare root or potted) 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.
