DESCRIPTION:
Most cudweed species are sparsely branching annuals. Purple cudweed, Gnaphalium
purpureum, is either a winter or summer annual or biennial as some plants
will survive into the second year to mature, thereby behaving as a biennial.
Creeping cudweed, G. collinum, is a perennial. The cotyledons (seed leaves) as well
as the first true leaves are covered with whitish to light gray woolly hairs.
The first true leaves are smooth, with smooth margins, and taper gradually toward
the base. The mature plant is sparsely branched, mostly erect, 8 to 20
inches
(20 - 50 cm) tall. The flower heads are crowded, spike-like, and densely
arranged on the stem or at the base of leaf stalks. The fruit bears bristly,
tuft-like
projections
that are shed at maturity.
