Cup Plant - Silphium perfoliatum

Cup Plant is a native perennial that grows from 3' to 8' tall and higher.

The flowers, appear from midsummer to autumn and look very similar to sunflowers, but are a lot smaller. The leaves are opposite, toothed and ovate. The petioles (the stalk that attaches the leaf blade to the stem) are widely winged and fused around the stem, forming a cup.

The Cup Plant is related to Rosinweed (Silphium integrifolium)) and the Compass Plant (Silphium laciniatum).

Silphium: old Greek generic name referring to resinous juice.
