The name Ironweed comes from its rigourous stems, which are hard and unbending, and thus difficult to bend or squash. What's more, it is full of beautiful flowers for butterflies and bees to pollinate plants.

Ironweed assists in supporting the local fauna, a source of food for birds as well as nectar to the pollinators. It is easy to care for and can make very tall and colorful additions to gardens.
How do I care for Ironweed?
Ironweed is not a demanding plant and depends mostly on the water in the soil, so it results in minimal watering only when there is a dry spell. The plant doesn't require much fertilization. Remove dead stems just before the onset of the growing season.

Plant Reproduction
Blue Flag Iris spread by rhizomes and self-seeding.
Planting bare-root perennials is best in any season if they are dormant; we only sell dormant plants. Planting them year-round is also excellent if you can get dormant perennials. When your bare-root perennials arrive, soak the roots in water for a few hours to rehydrate them. Lant by digging a hole wide enough to spread the roots comfortably and deep enough to place the top portion crown (where the roots meet the stem) at or slightly above ground level. Position the plant in the hole, backfill with native soil, and gently firm the soil around the roots—water well after planting to settle the soil around the plant and eliminate air. Apply a 2-3 inch layer of mulch to keep weeds at bay and moisture locked in, keeping the mulch away from the crown. Irrigate plants regularly during the first few weeks of drought; never water in full sun, and water late in the evenings to ensure the roots are established well. Fertilize sparingly in the first year, using a balanced, slow-release fertilizer in subsequent years as needed.
