Gardeners' Notes:


On Feb 21, 2020, sj7 from Marlborough, MA wrote:

I grew this is a large, informal garden in Michigan, where it was trouble-free, reliable, and quite handsome. For me, it never reseeded enough to be a nuisance, and it grew in some fairly lean soil with no pampering. Not for the small or formal garden, but if you have room and like a natural look, Id highly recommend it.

I've seen this twice planted in southeast PA. Handsome perennial, but a large one that needs room. It is not for the refined garden, but great for very informal or naturalistic landscapes and gardens. Easy to grow in most soils and no serious problems. Can be dug up and divided like many other perennials. Native from northern Florida to east Texas up north into Ontario and Quebec. Good pollinator plant for bees and butterflies and seed good for birds. Sold as seed or plants by some native plant nurseries as Prairie Moon in southern MN.

Easily grown in dry to medium wet, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Plants grown in dry soils tend to be shorter, open and somewhat spindly. Plants grown in medium wet soils with consistent moisture tend to be taller and fuller. Tolerant of heat, humidity and drought. Prompt deadheading of spent flowers may encourage additional bloom and prevents any unwanted self-seeding. Freely self seeds, and in optimum growing conditions will naturalize to form large colonies. If grown in borders, division may be needed every 2-3 years to maintain robustness.
