Overview
Registered in 2010, Hosta 'Cosmic Prize' is a large cultivar resulting from the cross (H. 'Sea Prize' × H. 'Beer Belly Blues') pollinated by H. 'Cosmic Hippie'. It is visually distinctive for its nearly round, moderately cupped leaves with dark green centers and streaked, greenish-yellow to white margins that are slightly rippled, combined with a moderate growth rate and a dense, mound-like habit.
In the Garden
Reaching 21 inches (53.3 cm) in height and 43 inches (109.2 cm) in diameter at maturity, 'Cosmic Prize' forms a substantial mound suitable for mid-border or as a specimen in part-shade to shade. Its large, cupped leaves provide textural contrast when paired with fine-leaved perennials such as ferns or Heuchera. The dark green scapes, rising 28 to 32 inches (71.1 to 81.2 cm), bear flowers typical of the genus.
Care Notes
Provide consistent moisture, particularly during establishment, and apply a balanced fertilizer in early spring as new growth emerges. Standard slug and deer precautions are advisable for optimal leaf condition in typical hosta-growing zones.
