Hosta 'Blue Cadet': Compact Blue Hosta for Small Spaces

Hosta 'Blue Cadet': The Dwarf Blue Hosta That Started a Trend

Hosta 'Blue Cadet', hybridized by Shaw-Aden and introduced in 1974, was one of the first small, intensely blue hostas—a "cadet" in size but a giant in impact. Its compact habit and true blue color opened new possibilities for hostas in small gardens and containers.

Compact Blue Perfection

The leaves are small, 4–6 inches long, heart-shaped, with a waxy, intense blue coating. The plant forms a tight, symmetrical mound 12–15 inches tall and 18–24 inches wide. Pale lavender flowers on 2-foot scapes in early summer. The blue color holds well in shade. Good substance for a small hosta.

Pioneer of Small Blues

Before 'Blue Cadet', blue hostas were mostly giants. This cultivar proved blue could come in a compact package. It tolerates morning sun (which intensifies the blue), prefers rich moist soil, and is hardy in USDA zones 3–9. Its influence echoes in countless later small blue introductions.
