Asclepias tuberosa
L., Butterfly Milkweed:
(Bayer Code:
ASCTU; US Code ASTU)
·
Native, long-lived, simple perennial that forms large, tuberous root with age
·
Produces multiple stems that are unbranched or only branched once flowering
commences
·
Leaves are lanceolate, alternate or opposite or somewhat whorled
·
Flowers are small, bright orange, red-orange or sometimes yellowish in large
terminal clusters, or smaller axillary clusters; some plants will bloom almost
all summer long
·
Fruit is a slender, upright pod; seeds are attached to windblown
The “weediness” of milkweeds has been revisited due to them being the main food
for monarch butterfly larvae; therefore, milkweeds no longer are being generally
considered as weeds to eradicate, and actually have legal protection in some
areas
