Rhinephyllum Muirii is a miniature, perennial, flowering mesemb forming clumps of many shoots. The leaves are inclined, up to 1 inch long, up to 0.4 inches wide, green but reddening in full sun and during cold weather with small whitish tubercles in the upper half, margins and keel with a white cartilaginous edge. The flowers are solitary and apical on a short pedicel, yellowish-white, up to 0.5 inches long, up to 0.6 inches across and open at night.
Rhinephyllum Muirii prefers free-draining soil, plenty of sun and ventilation, and regular light watering in the right season.
Mesembs require a loam-based compost with the addition of extra drainage material such as horticultural grit or perlite. They all like good light conditions and plenty of ventilation.
It is suitable for Container, Rock Garden & Xeriscaping.
