Early flowering, primrose yellow on spiny cushions.
One of the early-flowering Saxifraga, the early buds nestled into the foliage promise us that spring is just around the corner. 'Boston Spa' has short, reddish stems with flowers of primrose yellow in March over spiny, greyish-green cushions. About 10cm (4") high.
A reliable variety that grows and flowers well and is very hardy. Suitable for a stone trough etc. but does well on the rock garden too. A cultivar of Saxifraga x elisabethae.
