Saxifraga 'Riverslea'

Keep in mind when planting that Riverslea is thought of as half hardy, so it will require protection in frosts and low temperatures. A soil ph of between 5.6 and 7.5 is ideal for Riverslea as it does best in weakly acidic soil - weakly alkaline soil.

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