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 from divisions helps prevent the center die out and gives you more of these alpine plants for your garden.

Can you split Saxifraga?

Propagating Saxifraga

Mature clumps can be divided in the spring.

Do you deadhead saxifrage?

They have a long flowering period so i think dead heading is helpful. It depends on the variety. Mossy saxifrages don't like to get too hot or dry out so in a terracotta pot you will have to be careful to keep the pot/roots cool and moist. They also don't like to be too wet so use a gritty soil.
