Sagina are mat growing hardy perennials mosses that reach about 10 cm in height.
Sagina have lime green lance shaped leaves, and bloom in the summer carrying tiny white flowers.
Their size makes them a great plant for using in rock gardens, as ground cover, and for the gaps in dry stone walls.
Some common names for Sagina include Irish Moss and Pearlwort.
Sagina subulata (Aurea); Golden Irish Moss) by darknesschildsin.
The seeds of Irish Moss and other Sagina species can be sown outdoors either in autumn or the beginning of spring. Once sown lightly cover the seed. Plants should be spaced about 10 cm apart unless it is a spreading variety, then they should be grown about 20 cm apart. Irish Moss likes to be grown in sunny areas that have afternoon shade, and thrives in a moist, light, and sandy soil.
If starting off indoors then do so about 7 or 8 weeks before the last frost of spring. It should take two or three weeks for the seeds to germinate at 12 degrees centigrade. Transplant them out after the last frost of spring.
It is easy to care for Sagina plants. They like moist soil so water them frequently; also give them a regular feed. It may be necessary to grow Irish Moss near plants that attract ladybirds as aphids love to feed on them.
