Gossamer threads bind harebell blooms (Campanula rotundifolia, Native).

Membranous skin encloses developing buds of nodding onion, then tears to expose the pendulous pink bloom (Allium cernuum, Native).

Most plant common names give little information about the species, but hairy golden aster accurately depicts this hirsute member of the Asteraceae (Heterotheca villosa, North Ridge).

Scarlet beeblossom petals become brilliant red with age (Gaura coccinea, Corral).

A new addition new to the ranch species list, Douglas' dustymaiden flowers consist only of ray flowers and no petals. Its ecological amplitude makes it a popular restoration species in the west (Chaenactis douglasii, Whaley).

Red fringed florets of blue gramma grass emerge in late June (Bouteloua gracilis, Whaley).

Scarlet globemallow possesses characteristics ideal for restoration: drought tolerance, rhizomatous growth, and an affinity for disturbed areas. Knapweed exudes a phytochemical, catechin, which inhibits native plants. A manipulated study showed catechin inhibited scarlet globemallow seedling establishment after knapweed was eliminated (Perry, 2005). Cooccurrence of these species in the study sites’s invaded areas suggests established globemallow tolerates catechin. For ranch restoration projects, using starts instead of seed may create greater globemallow cover in areas formerly dominated by knapweed (Sphaeralcea coccinea, Whaley).
