Our Native Irises: Pacific Coast Irises
Iris macrosiphon: Bowl Tube Iris (Ground Iris)
The bowl tube iris occurs in the northern half of California.
Iris macrosiphon flowers are a myriad of colors (almost any color found in any of the Pacific coast irises) ranging from deep indigo blue to violet to lavender, creamy white or yellow. The sepals are moderately upright and then arching downward with prominent veins, a deeper color of the sepals color. The petals are upright and slightly spreading, shorter and narrower than the sepals, similar in coloration. The inflorescence has (one) two flowers. The flowering stalk is much shorter (almost stalk-less to 11-inches) than the attending leaves. The leaves are green to dark green, upright to slightly spreading, and basal with a white base, from branching rhizomes with a few fibrous roots occurring as individuals or small clumps.
Iris macrosiphon is found growing in sunny openings and meadows.
