Description
 
 

Sweet William catchfly is a 4 to 27 but usually 8 to 16 tall, erect, annual forb that rises from a slender taproot. When young the plant forms a basal rosette of leaves. Later it sends up flowering stems.

The stems are erect and unbranched below the inflorescence. They are hairless and are more or less covered with a whitish, waxy coating (glaucous). They sometimes have sticky areas below the upper nodes.

Basal leaves are broad, lance-shaped to spatula-shaped, ¾ to 2 long, and hairless. They wither before the plants flower. Stem leaves are opposite, lance-shaped to elliptic, to 2 long, and from less than ¼ to 1 wide. They taper gradually to a pointed tip with straight sides along the tip. They are attached to the stem without a leaf stalk and are more or less clasping. They are hairless and more or less glaucous. The margins are untoothed.

The inflorescence is a dense, head-like or branched cluster of flowers. Each cluster is subtended by a pair of long or less lance-shaped bracts.

Flowers are about ½ wide when fully open, and are on a short, upright stalk.

The sepals are tinged purple and fused at the base into a tube (calyx) terminating in 5 short, erect lobes. The calyx tube is ½ to long, and about wide, and constricted at the base with a navel-like indentation. It is club-shaped, gradually widening toward the apex. It has 10 major veins that are raised on the surface (prominent), forming ridges.

The 5 petals are pink, unlobed, horizontally spreading, with a stalk-like narrow base (claw). There are 10 stamens that are slightly longer than the petals and 3, sometimes 4, styles, also longer than the petals.

The fruit is a 3-chambered capsule with 6 or 8 spreading teeth at the top.
