Seeds of Asclepias tuberosa
L., Schizachyrium scoparius (Michx.) Nash, and Vernonia gigantea (Walt.) Trel.
These include four members of the genus Helianthus (the sunflowers), Silphium integrifolium (rosin-weed), Silphium perfoliatum (cup plant), Solidago speciosa (showy goldenrod), Allium (wild onion), two species of Anermone, Liatris aspera (rough gayfeather), Hedyotis nigricans (narrowleaf bluet), Asclepias tuberosa
(butterfly milkweed), Calylophus serrulatus (plains yellow primrose), and Aster sericeus (silky aster).
The only other plant species showing evidence of deer browsing were the forbs Asclepias tuberosa
and Lithospermum canescens and the woody plant Rosa arkansana.
Some species, including Asclepias tuberosa
(butterfly milkweed) and Silphium integrifolium (rosinweed), had both low germination and low field emergence.
For example, you have planted pleurisy root (Asclepias tuberosa
) for your brother's bronchitis and your prize ram finds it a fine treat and is poisoned; or, a neighbor cultivates flax (Linum ussitatissimum), unaware that immature (attractive) seeds and their pods are toxic.
The goals of this study are: (1) to test whether the milkweed, Asclepias tuberosa
(butterfly weed), is most effectively pollinated by butterflies, as suggested by its floral traits and the great variety and numbers of butterflies observed to visit its flowers; (2) to accurately measure several components of pollination effectiveness for each flower-visiting taxon; and (3) to determine whether the pollination spectrum (i.e., the ranking of flower visitors by pollination effectiveness) of A.

Another non-invasive, orange-flowered plant (Asclepias tuberosa
) is a milkweed that's not the first choice for Monarchs, but many other butterfly species depend on it.

and Helianthus divaricatus.
* Butterfly weed (Asclepias tuberosa
) may be a rangy-looking plant, but because it's so cherished by monarch butterflies, this perennial is especially rewarding to grow.
