Growing up in Pueblo West as a small child, I met Stanleya - my what a spectacular plant. A true desert beauty. I see it as high as 6,500'-7,000' but not much higher. It can be grown as an annual at higher elevations or in a protected warm, sunny spot. Full, blazing Colorado sun and lean, lean soils are required to make this happen. A real show stopper - and the pollinator's love it! Spring blooming.
Provide 1-2 months stratification or plant from fall to March in areas with winter. Plant seed lightly. (1/16th-1/8th") Stands 2-4' tall.
