Irish moss is native to Europe, from Iceland south to Spain, and east to southern Sweden and Romania.
In the wild it can be found growing on dry sandy or gravelly soils. Though not a true moss, Irish moss forms a thick, dense mound of bright green leaves, less than 10cm tall. In spring the plants are covered with tiny, star-shaped white flowers. The cultivar (Sagina subulata ‘Aurea’) is also called Scotch Moss and has bright yellow foliage
An extremely popular groundcover plant, this forms a very low moss-like carpet of bright green foliage.
Tiny little white flowers begin to appear in late spring.
Excellent for filling in between the cracks of flagstone paving, in the rock garden as a lawn substitute. Dislikes both drought and soggy wet soils. Easily divided in early spring or fall, by ripping up the clump into smaller pieces. In hot, humid summer regions this sometimes melts out and becomes unattractive in mid summer, usually reviving in the fall. Not a good choice for full shade. Evergreen.
They spread rapidly to form a carpet that looks especially nice against gray stone.
Once established the plants can take a lot of foot traffic and are therfore excellent to plant between pavers or alongside pathways.Irish moss is great planted next to water features, or amongst rocks and pebbles, in Japanese and woodland gardens.
Sagina is evergreen and does well in temperate gardens where it can be planted in full sun or semi-shade; it will not thrive in full shade.
It is cold and frost hardy and is not suited to hot, humid gardens because the plants will melt out in mid-summer, only reviving again in autumn. In hot regions it requires some shade during the heat of the day and regular watering.
Although Irish moss thrives in gravelly well-drained soil it will grow in most garden soils, normal, sandy or clay; neutral, acid or alkaline. Mature plant size can vary according to growing conditions and climate, +- 2 to 5cm tall and +-15 to 30cm wide. Divide plants in Summer/Spring
Ideal ground cover for Zen gardens and is used in bonsai plantings as a decorative ground cover
