The Story

Plant Bio

A succulent perennial from South Africa, forming a low-growing mound of fleshy, rounded, blue-green leaves. It is prized for its unique foliage that resembles nasturtium leaves and its long bloom season of bright yellow, daisy-like flowers. The specific epithet 'tropaeolifolius' means 'nasturtium-leaved', perfectly describing its most distinctive feature. The succulent, peltate leaves are an unusual blue-green color, providing year-round interest. It is exceptionally drought-tolerant and excellent for water-wise gardens, rockeries, and containers.

Uses & Benefits:

Vivid yellow flowers add cheerful color to gardens and containers.
