saxifrage 'Cumulus'

Grow in a moderately fertile, very well-drained, neutral to alkaline soil in light shade. A rock garden or crevice garden is ideal so as to keep the roots cool. Troughs, sinks or an alpine house are also ideal places in which to grow 'Cumulus'. Use shallow pans of two parts John Innes No 1 compost and one part limestone chippings

None required excet for deadheading

Propagate by seed in autumn in containers in an open frame (don't expect cultivars to come true from seed). Individual rosettes can be detached in spring as root cuttings in late spring or early summer

Aphids, glasshouse red spider mite and vine weevil may be problematic

Usually trouble free
