Growing Saxifraga Plants In The Yards
Saxifraga is a plant genus that is part of the Saxifragaceae family. It contains over 450 species of perennial and annual plants that are usually found in the north and south temperate zones, often with the common name “rockfoil.” Mossy rockfoil has no special needs, provided you give it a location with some shelter from wind and hot sun. The plants require moist soil, especially in spring when they are growing the most. You can plant this Saxifraga from seed but for faster plants, divide a mature clump. Seeds require cold stratification for germination and can take two to three years to bloom. Growing rockfoil plants from divisions helps prevent the center die out and gives you more of these alpine plants for your garden. This species needs a moist rich loam for best performance. Mix in a little compost with existing soil at planting time.
Mulch around the plants to conserve moisture and help prevent weeds from growing up into the center of the plant as it spreads. Water twice per week in summer. In colder zones, mulch over the plant lightly to protect the roots from freezes, but pull away the mulch in early spring. This allows the new growth to burst out without having to push through the layer of mulch.
