Loved by bees and butterflies, this diminutive shrub has tiny, narrow, dark-green leaves which are topped with masses of small, bright yellow flowers in summer. | ||||||||||||
Sowing and/or growing instructions | ||||||||||||
Although very small, the seeds of the rock rose have a very hard seed coat and germination can be slow and erratic. Spring-sown seeds (under glass) are best lightly scarified, which can be done between two sheets of fine sandpaper. However, early-autumn sowings in a cold frame may be a better option, so that microbial activity over several months can help break down the seedcoat, for germination in spring. In either case, sow thinly on the surface of good quality compost, covering with a sprinkling of sieved compost or fine vermiculite, growing on seedlings in individual pots or modules and planting out well-drained soil when large enough. |
