Longbranch Frostweed is an erect plant with a 5-petal yellow flower. The flower petals
overlap sometimes making the flower look like a little yellow satellite dish.
The very center part of the flower is white surrounded by orange-tipped stamen.
Stems have 1 to 2 flowers that bloom in May-June. Leaves are alternate,
narrowly-oblong and taper at both the base and the tip. Stems are scattered and
branching and the branches become longer than the main stem. This differentiates
it from the very similar species, Hoary Frostweed (Helianthemum bicknellii)
where the branches do not become longer than the main stem. In addition, Hoary
Frostweed tends to have more flowers (2-10) and blooms later in the year
(June-July).
