Asclepias tuberosa 'Hello Yellow'
Our products are available for retail purchase only. Please call for availability as stock levels fluctuate throughout the season. We are unable to ship plants or other products.
A virtually hassle-free perennial, this cultivar of our native A. tuberosa offers three months of golden yellow blooms from early through late summer. Deadheading the flowers will stimulate another bloom cycle about a month after the first one. The flowers, which are heavily laden with nectar and pollen, are particularly attractive to hummingbirds, Monarch butterflies, bees, and other beneficial insects.
Hardiness Zone:3 - 9
Gather bouquets of Asclepias all summer long; the long stems are wonderful for cutting and are long-lasting. Following the fabulous flowers, green fruits develop which rupture to reveal seeds with long, silvery-white, silky hairs reminiscent of its cousin, common milkweed. These are great to use in dried flower arrangements.
Butterfly Weed Growing and Maintenance Tips
Asclepias tuberosa is a prairie plant native to North America from S. Ontario and New York, west to N. Dakota, southwest to Colorado, Arizona, and New Mexico, and south to Florida (zones 3-9). Found naturally in dry fields and on slopes, it does not require rich soil or much moisture. A full day of sun is best along with a slightly acidic, sandy-humus-loam that is well-drained (especially in winter). Once established, Butterfly Weed is drought-tolerant and requires little care. Though it is perfectly cold-hardy in the north, mulching plants in winter will help prevent frost-heaving. In spring, trim back last year's growth and await the beautiful new foliage which will appear quite a bit later than other perennials.
