Saxifraga 'Hirtifolia'

Keep in mind when planting that Hirtifolia is thought of as half hardy, so remember to protect this plant from frosts and low temperatures. A soil ph of between 5.6 and 7.5 is ideal for Hirtifolia as it does best in weakly acidic soil - weakly alkaline soil.

As Hirtifolia is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
