Hosta Winter Thunder OS

Hosta ‘Winter Thunder’ is a distinctive streaked hosta selected as a sport of ‘Winter Lightning’. This cultivar is valued for its bright, energetic foliage and the natural variation that comes with streaked genetics, making each plant unique and especially appealing to collectors.

The leaves display green foliage with bold yellow streaking that radiates through the leaf blade. As an unstable streaked hosta, pattern expression may vary from plant to plant and can shift as the plant matures, which is a defining characteristic rather than a flaw. The streaking remains most prominent when grown in consistent shade, where color contrast is strongest.

Plants form a compact, well-shaped clump reaching approximately 14 inches tall and 20 inches wide. ‘Wiinter Thunder’ is an excellent choice for containers, shaded borders, and specialty hosta collections where its streaking can be appreciated up close.

A bright, fertile, and highly collectible streaked hosta with strong breeding and display potential.
