Hello Yellow Butterfly Weed

‘Hello Yellow’ is a golden-flowered selection of butterfly weed, grown for a long summer display on a compact, upright perennial. The cultivar is documented at about 24 inches tall and wide and is hardy across USDA zones 3–9 ([Walters Gardens](https://www.waltersgardens.com/variety.php?ID=ASCHY)). ## Landscape Use Use this milkweed in sunny perennial borders, prairie-style plantings, or pollinator gardens, where its warm yellow clusters contrast with grasses and blue or purple flowers. Its nectar and pollen attract bees, Monarch butterflies, and hummingbirds; the broader species also serves as a host plant for several butterfly caterpillars ([University of Wisconsin Horticulture](https://hort.extension.wisc.edu/articles/butterflyweed-asclepias-tuberosa/)). ## Siting and Seasonal Interest Give the plant a full-sun position with sharply drained soil. Walters Gardens reports blooms from early through late summer, with a second flush possible after deadheading. Butterfly weed develops a deep taproot and is slow to establish, so plant it where it can remain undisturbed; flowering may be sparse for the first couple of years ([North Carolina Extension](https://plants.ces.ncsu.edu/plants/asclepias-tuberosa/common-name/common-butterfly-lily/)). ## Maintenance Water regularly during establishment, then let the soil dry somewhat between waterings. The established plant is drought tolerant and needs little routine care. Removing spent flower heads can prompt another bloom cycle; leave some pods if you want natural reseeding or seed heads for arrangements.
