dried purple flowers with grassy leaves

Blazing Star,also calledGayfeather,is a hardywildflowerthatcan live for decadesinColorado’s semi-desert climate.Rising up to 4’ tall each autumn,its bright purple flowersact as magnets for monarchs, birds and busy bees,long afterothersummerblooms have dried up.

Native to North America where it grows from central Canada to northern Mexico,this plantis commonly found along the interface of the Great Plains and the Rocky Mountains, extending eastward into the prairie states and provinces. Blazing Star grows well in Boulder County, where dense clay soils make it difficult for water to soak into the ground quickly.What makes thisnative plantso successfulalso makesit beneficial to the ecosystem. Blazing Starhas adeeproot system that can allow surrounding soilsto absorb and retain water.Itsthick root may reach 16 feetdeep,makingit resistant to drought.(Asnativevegetation is replaced with popular turf grasses, less stormwater is absorbed into the ground, leading to more runoff,water pollutionand potential flooding).

Technically, the ‘root’ ofBlazingStar is acorm,a modified stem adapted to store food that is sometimes confused with abulb. A corm is solid, in contrast, a bulb is a modified bud made up of layers of scales and leaves as in an onion. The plant kingdom has evolved many different forms and structures to survive; adaptations that allow a plant to extend its reach (literally) into the surrounding environment without moving from its fixed spot on the earth.
