DESCRIPTION:
Seedlings of velvetleaf, a summer annual, have one cotyledon that is round
and the other may be slightly heart-shaped. Cotyledons are covered with
fine, soft hairs. Mature plants may be 5 feet (1.5 m) or more tall, with
alternate, heart-shaped leaves that are pointed at the tip. Five-petalled,
yellow flowers are borne on stalks arising from the leaf axils. The stamens
are fused to form a tube. Fruit capsule has 9 to 15 segments, each
containing gray-brown seeds. Seeds can remain viable in soil for 50 years.
If infestations are allowed to persist and produce seed, this weed can be
troublesome.
