The genus Hypoxis, often called the “star flowers” of grasslands and rocky places, is a captivating group of small to medium geophytic perennials known for their bright, sun-catching blooms and resilient underground corms. Found across Africa, Asia, Australia and the Americas – with southern Africa being a major centre of diversity – Hypoxis species thrive in seasonal climates where fire, frost, drought and summer rain shape their life cycle. Their silky, grass-like leaves and charming starry flowers (usually golden yellow, sometimes pale or cream) appear like living sparks scattered through veld, slopes and open habitats. Whether admired for their medicinal history, their ecological toughness, or their botanical elegance, Hypoxis is a genus that embodies wild beauty and quiet endurance, rewarding growers with naturalistic charm and reliable flowering when cultivated in the right rhythm.

Hypoxis costata – Kharatsa Stargrass

For a true South African native that looks perfectly at home in a veld-inspired garden, Hypoxis costata delivers. Its strap-like leaves form a grounded, architectural tuft, while the bright yellow star flowers bring that unmistakable Hypoxis glow – especially striking when several plants flower together.

This species is recorded from South Africa (including KwaZulu-Natal, Eastern Cape and Free State) and neighbouring countries and flowers mainly in spring to early summer (often around September to November). It occurs in open areas and responds well to seasonal moisture, producing blooms on slender stems that sit neatly above the foliage.

It’s an excellent seed choice for indigenous gardeners, landscapers, and wildflower growers wanting a hardy, naturalising species. Sow it for meadow plantings, sunny borders, or restoration-style projects – then stand back and enjoy those bright stars returning year after year.
