Hosta is a genus of hardy herbaceous perennial plants commonly grown as shade-tolerant ornamentals for their foliage.
Hosta is a genus of hardy herbaceous perennial plants grown for their shade-tolerant foliage. Native to eastern Asia, they are a staple of Canadian shade gardens.
What it is
Hostas are clump-forming perennials in the asparagus family (Asparagaceae). They are known for ribbed, basal leaves in green, yellow, blue, or variegated patterns, and produce tubular white to bluish-purple flowers on stalks in summer.
Why it matters
Hostas are popular ornamentals because they are hardy, long-lived, and easy to grow in temperate gardens. Thousands of cultivars offer diverse foliage forms and colours, making them a reliable choice for shaded or partially shaded garden beds.
Key details
The genus is native to China, Japan, Korea, and the Russian Far East. In cultivation, hostas thrive in partial to deep shade and are widely planted across Canada, where many varieties tolerate cool climates.
