AKA Prairie Mimosa

HERB LAYER

Illinois Bundleflower
Botanical name: Desmanthus illinoensis

  • Cold hardiness zones: 5-9
  • Soil pH: Prefers neutral to slightly alkaline soils.
  • Watering needs: Moderate; drought-tolerant once established.
  • Food forest layer: Understory/shrub layer.
  • Which parts of the plant are eaten as food: Seeds and young leaves.
  • Blooming Season: June to September.
  • Harvest season/regularity: Seeds mature in late summer to early fall.
  • Fruiting age: Generally starts fruiting in the second year.
  • Age of maturity (full size and peak fruiting): Reaches full size in 2-3 years.
  • Average mature yield: Varies, as the plant is primarily grown for soil improvement and nitrogen fixation.
  • Pollination for Fruit: Self-pollinating.
  • Size at maturity: About 3-6 feet in height.
  • Sun needs: Full sun to partial shade.
  • Preferred habitat: Prairies, roadsides, open woods.
  • Growth rate (vigor): Moderate to fast.
  • Natural reproductive rate (and methods): Seeds, and sometimes vegetative reproduction.
  • Propagation method: Seed; scarification improves germination rates.
  • Average life span: Perennial, lives several years.
  • Good companion plants: Prairie grasses, legumes, wildflowers.
  • Plant family: Fabaceae (Legume family).
  • Taproot: Yes, deep taproot.
  • Predators: Generally pest-resistant.
  • Other common problems/solutions: No major issues known.

Notes:

  • Ecological functions/uses: Nitrogen fixer, soil improver, wildlife food source.
  • Food uses: Seeds are high in protein; can be roasted or used like lentils. Young leaves are edible.
  • Food Flavor/Taste: Seeds have a nutty flavor; young leaves are mild.
  • Cautions: Ensure proper identification as some parts may be inedible or require specific preparation.

Propagation of Illinois Bundleflower

To propagate the Illinois Bundleflower (Desmanthus illinoensis), you’ll primarily use seeds, as it’s the most effective method. Here’s a step-by-step guide:

  1. Seed Collection: Harvest the seeds in late summer to early fall when they are mature. They are typically found in clusters on the plant.
  2. Seed Preparation: The seeds of Desmanthus illinoensis have a hard outer shell, so they require scarification to improve germination. This can be done by gently rubbing the seeds with sandpaper or nicking them with a knife. Another method is to soak the seeds in hot water for a day or two. This process breaks down the tough outer coating and encourages germination.
  3. Sowing Seeds: Plant the prepared seeds in well-draining soil. They can be sown directly in the garden where you want the plants to grow, or started in pots. If you’re starting them in pots, use a good quality seed starting mix. Plant the seeds at a depth of about a quarter to a half inch.
  4. Watering: After sowing, water the soil gently but thoroughly. Keep the soil consistently moist but not waterlogged until germination occurs.
  5. Germination: Seed germination can take anywhere from one to three weeks, depending on the conditions. The seeds need warmth to germinate, so if you’re starting them indoors, a heating mat can be beneficial.
  6. Transplanting: If you started the seeds in pots, transplant them to their permanent location once they are big enough to handle and after the danger of frost has passed. The seedlings should be spaced about 2-3 feet apart to allow enough room for growth.
  7. Care After Transplanting: Water the new plants regularly until they are well-established. Once established, they are quite drought-tolerant.

Remember, the Illinois Bundleflower is a perennial and will grow back year after year from the same roots. It’s a low-maintenance plant once established and can be a great addition to your permaculture garden for its nitrogen-fixing properties and as a food source for wildlife.
