8-12" x 6" wide (seed propagated). Native to the prairies of eastern NM and Co, this Indian Paint Brush grows well throughout the high plains and intermountain region. Castilleja is a genus of parasitic plants that must tap into the roots of other plants for their nutrients. We send it with a pot of Fringed Sage as the host plant. It loves other prairie natives as companions like, Liatris punctata (Gayfeather), Zinnia grandiflora (Prairie Zinnia), Scutellaria (Skullcap), and grasses like Schizachyrium (Little Bluestem) -- all thrive in the same growing conditions. Zones 4-7
