Hello Yellow delights with 3-inch flowerheads simply jammed with blooms. Showy seedpods follow the flowers, and these are useful in dried arrangements as well as pretty on the plant. Indifferent to heat, humidity, drought, poor soil, and more, Hello Yellow is just as carefree as a perennial can be, and it seems to flower all summer long! The visiting butterflies and hummers simply add to the color show. What a glory!
Expect Hello Yellow reaches 2 to 2½ feet tall and 2 feet wide, a nice size for the mixed border, blazing bed, or patio specimen. Unforgettable in a mass planting, the blooms are also good in fresh or dried displays, with good color retention and stiff texture.
Like most plants, this Asclepias is happiest in well-drained soils, but it will put up with a lot of hardship, including poor, dry soil and long periods of drought. It needs full sun and plenty of it to reach its peak performance. Hardy just about anywhere in the U.S. Zones 3-9.
