Melanthium virginicum Bunch Flower



Qty

 Confirmed Request

Bunch Flower (Melanthium virginicum) prefers consistently rich, moist soil conditions and full sun or dappled shade. The thick stems can bring it to heights of 5'.  It's not a very well-known native yet, but we think it makes a stunning addition to a garden or formal planting with its large clusters of fragrant flowers in June and July. The flowers are white to cream in color, but as the weeks pass the flowers turn green, then maroon, and finally blackish in color (see photo) adding fall interest to your garden or prairie. Our experience in adding Bunch Flower to our diverse prairie plantings here at Prairie Moon is that it establishes well, is competitive, and long-lived. We highly recommend this under-appreciated native!

Other names include Virginia Bunchflower Lily and Veratrum virginicum.

3 Questions asked on Melanthium virginicum






Q Iris • April 30 Does "competitive" mean it spreads aggressively? Or that it doesn't allow others to crowd it out?
A Prairie Moon • May 3 Hi Iris, In this context, competitive means that it can hold it’s spot in a prairie and won’t allow others to crowd it out. In our experience, this is not an aggressive species.
Q Chelsea • May 4 How many years does it take to flower when started from seed?
A Prairie Moon • June 4 As a long-lived perennial, Bunch Flower can take 3-5 years to bloom if started from seed.
Q Lora • May 11 What pollinators does this plant support? Do you cut these back in the winter or spring?
A Prairie Moon • May 27 Hi Lora, According to Illinois Wildflowers, “Mostly flies and beetles visit the flowers of this plant, where they feed on the easy-to-access nectar, although some insect species may also feed on pollen. These floral visitors include Syrphid flies, Tachinid flies, blow flies (Lucilia spp.), Muscid flies, Anthomyiid flies, weevils, tumbling flower beetles, and flower scarab beetles. Some bees and wasps may also visit the flowers (Robertson, 1929).”

If or when you cut back the plant depends on your gardening style. If you don’t want to, you don’t need to cut the plant down; it will grow back through the thatch. Most gardeners like to tidy things up a bit at some point and choose to cut them back. If you do cut them back, we recommend waiting until spring so the standing vegetation can be used by overwintering insects.

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.

*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
Retail SEED orders over $100.00 ship free! Custom seed mixes or wholesale seed sales over $100, add 5% of the total seed cost
(for orders over $1,000 a package signature may be required)

BARE ROOT and POTTED PLANTS $50.00 and under: $7.50
over $50.00: 15% of the total plant cost
(for orders over $1,000 a package signature may be required)

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

**We are required to collect state sales tax in certain states. Your state's eligibility and % will be calculated at checkout. MN State Sales Tax of 7.375% is applied for orders picked up at our MN location. 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 32/38/50 plugs and 3-packs) typically begin shipping early May and go into June; shipping time is heavily dependent on all the species in your order being well-rooted. If winter-spring greenhouse growing conditions are favorable and all species are well-rooted at once, then we ship by order date (first come, first serve).  We are a Midwest greenhouse, and due to the challenges of getting all the species in the Mix & Match and Pre-Designed Garden Kits transit-ready at the same time, we typically can't ship before early May.  Earlier shipment requests will be considered on a case-by-case basis.

*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. We send tracking numbers to your email address so please include it when you order.
