(Asclepias tuberosa) Beautiful bright orange flowers cover the plant
from mid-summer until early fall. Attracts bees,
hummingbirds, moths, and butterflies. Blooms
reliably from seed the first year if sown early. Plants
will reach 2-3' tall in dry sandy soil and in welldrained
loams. Perennial. Hardy to zone 4.
8-10 weeks before planting out
Green Thumb Tip Sow seeds indoors just beneath surface of soil in
pots. Germination will occur with no treatment
but benefits from cold stratification. Place pots in
plastic bags and refrigerate for three weeks. Remove
plastic and provide light and 50-75°F thereafter. Do
not overwater. Transplant outdoors when light frost
is still possible.
