Description
Irish moss (heath pearlwort) is a perennial of the pink family. It grows 2–5 cm tall and forms a low, dark green, cushion-like mat of long, creeping shoots with narrow linear leaves arranged in whorls.
It flowers from April to July. The flowers are tiny, white, numerous and honey-scented. They grow on long stalks and have five petals and a yellow centre.
It is used in rock gardens and instead of a lawn in less-trodden places. It looks beautiful planted among stones and is perfect for filling the gaps between paving slabs.
There is a variety with golden-yellow foliage that is very decorative throughout the growing season.
