Helianthemum canadense of Michigan Flora
Dry sandy plains, hillsides, dunes, usually open or with thin tree cover (pines, oak, and/or aspen) or scattered junipers.
Older plants (collected later in the summer) may not display the scattered long hairs on the upper surface of the leaves, which are quite evident when early petaliferous flowers are present, but such late plants will usually have ample cleistogamous flowers or fruits (with their larger capsules and rudimentary outer sepals) to make identification possible. Furthermore, if they have the large fruits developing from early petaliferous flowers, these will be much overtopped by leafy shoots.
