Hello Yellow Butterfly Bush Milkweed - Asclepias

A virtually hassle-free perennial, offering three months of vanilla-scented, white flowers in clean clusters from midsummer to early fall. 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, butterflies, bees, and other beneficial insects.
