How to grow
Ironweed is very adaptable and can grow in a wide variety of soil types. Prefers rich moist soil, but will thrive even in orange clay. Planting in full sun and shelter from strong winds will prevent having to stake plants. Plants can tolerate drought and periodic flooding with ease.
Care and maintenance
Cut the thick flowering stems down to the ground any time after a hard frost.
Where to plant
At the back of flower beds to add height and color to the summer garden. It is also at home in more informal plantings, like meadows, edges of ponds, and rain gardens.
When to plant
Whenever the ground is not frozen. Plants establish quickly and love the summer heat.
Spacing
3 to 4 feet apart when planting in a group.
When will my plant flower?
Plants purchased and planted before May will flower their first year if sited in a well-prepared spot and kept watered.
Native habitat and range
In the wild, Giant Ironweed grows in meadows, bottomlands, and along streambanks from New York and Michigan to Florida and Texas.
