Skyrocket (Ipomopsis aggregata), or Scarlet Gilia, is native to western North America, including parts of the United States and Canada. It can be found in a variety of habitats such as dry meadows, open woodlands, rocky slopes, and subalpine regions. Skyrocket is exceptional for its stunning scarlet-red tubular flowers that bloom in tall clusters.
Skyrocket typically blooms from late spring to mid-summer when its flowers open up in spectacular display, attracting attention from both humans and pollinators. The tubular flowers of Skyrocket have coevolved with long-tongued pollinators such as hummingbirds and hawkmoths, who are attracted to the abundant nectar reserves within the flowers. These pollinators play a vital role in the plant's reproduction as they transfer pollen between plants, ensuring genetic diversity and the production of viable seeds.
Skyrocket is both beautiful and resilient. It can adapt to a wide range of environmental conditions, from hot and arid to cooler, subalpine climates. Plants can tolerate various soil types, including sandy, loamy, and rocky soils in both acidic and alkaline conditions. Seeds can be sown directly on the surface of the soil in the fall or spring and lightly covered with sand. They have moderate germination requirements and typically benefit from full sunlight and sandy soils with moderate moisture in spring. Well-draining, mineral soils are crucial in fall and winter to prevent foliar rot.
