Overview
Registered in 2010, Hosta 'Cosmic Sensation' is a giant-sized cultivar resulting from the cross (H. 'Fudge Ripple' × H. 'Cosmic Hippie') pollinated by H. 'Geneva Remembrance'. It is visually distinguished by its very large, nearly round, medium green leaves with flat margins that are streaked greenish yellow to creamy white, combined with a lightly cupped and moderately corrugated texture.
In the Garden
With a mature spread of 44 inches (111.8 cm) and height of 28 inches (71.1 cm), 'Cosmic Sensation' forms a dense, mound-like clump at a moderate growth rate. It is best sited in partial to dappled shade, typical for hostas, where its substantial foliage can develop without scorch. Its large, rounded leaves make it a suitable specimen or accent plant in the middle to back of a shaded border, pairing well with ferns, astilbes, and other shade-tolerant perennials.
Care Notes
Provide consistent moisture, particularly during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Standard slug and deer precautions are advisable, as the large, lush leaves are attractive to both pests.
