Saxifraga 'Cumulus'

Keep in mind when planting that Cumulus is thought of as half hardy, so it will require protection in frosts and low temperatures. Try to keep the ph of your soil between the range of 5.6 and 7.5 as Cumulus likes to be in weakly acidic soil - weakly alkaline soil.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Cumulus is a half hardy plant.
