It is a clumping, bulb-like perennial. And a deciduous plant with narrow, strap-like leaves, almost like a wide grass. If kept outdoors will loose its leaves in preparation for winter.
A single stalk thrusts the beautiful flower heads skyward and results in these plants having beautiful flower heads that form in rounded clusters of 7-10 cm. The funnel-shaped florets are clustered together, several dozens in one flower head, anywhere from 50-70 florets. The colors of these flowers range from pale blues to deep purple-blues or indigo.
