Ipomopsis aggregata ssp. aggregata
Ipomopsis aggregata (Pursh) V.E. Grant ssp. aggregata
Scarlet Gilia, Skyrocket
Polemoniaceae (Phlox Family)
Synonym(s): Cantua aggregata, Gilia aggregata, Gilia aggregata ssp. euaggregata
USDA Symbol: IPAGA3
The showy biennial, skyrocket or scarlet gilia, bears clusters of tubular flowers scattered along the upper portion of its stiff, unbranched, 6 ft. stem. The showy flowers are normally brilliant red but sometimes pink or even pale orange. Leaves are mostly near the base of the plant and divided into narrow segments.
In nature, browsing by mule deer and elk prior to the flowering season stimulates growth of multiple flowering stems and increases flower production. Hummingbirds also visit these flowers for sustenance.
