Starry saxifrage

 


Starry saxifrage (Saxifraga stellaris) is a common plant found on wet, stony ground in the mountainous areas of the British Isles. Its tough, penetrating roots exploit the natural cracks and crevices in the rock and anchor it so firmly that it has gained a reputation, like other saxifrages, of being able to carve out its own foothold by actually cracking the stone. This belief, still widespread though erroneous, is reflected in the origin of the plant’s scientific name Saxifraga, which combines the Latin words saxum, meaning ‘rock’ and frango, meaning ‘break’.

The plant grows up to 10 inches (25 cm) in height. It has a rosette of toothed leaves at the base, but the upper parts of the stem are leafless. The low-growing leaves are less exposed to mountain winds, and their closeness to each other help to conserve moisture. The leaves are short-stalked, toothed and hairy on the top surface.

Flowers appear between June and August. They are white with conspicuous red anthers. There are two yellow spots at the base of each petal. The sepals are bent back. The seed capsule splits to the middle or below when ripe.

Ancient medical lore often believed that a plant with particular characteristics that related to an element of human anatomy had been prescribed by God as a cure for ailments relating to that element. Thus a decoction of "stone breaking" starry saxifrage was applied to curing kidney and gall stones in the human body. A 17th-century medical textbook also recommended that saxifrage roots, mixed with wine and vinegar, would cure the plague.
