Oscularia deltoides ‘Stilton Blue’ is a beautiful evergreen succulent admired for its compact, spreading habit and distinctive blue-grey foliage. Its thick, triangular leaves feature tiny reddish teeth along the edges, while the stems often develop attractive purple tones, creating year-round colour and texture. As the plant matures, it forms a dense, low-growing mat that is ideal for rockeries, retaining walls, containers, and water-wise landscapes.
During spring and summer, the foliage is covered with masses of fragrant lavender-pink to purple daisy-like flowers with bright yellow centres. The blooms open during the afternoon and often blanket the entire plant, attracting bees and other beneficial pollinators. Highly drought tolerant and easy to grow, ‘Stilton Blue’ is an excellent choice for gardeners seeking a colourful, low-maintenance groundcover.
