Semponium ‘Sienna’

Semponium is a ground-breaking, world-first cross between Sempervivum and Aeonium. The stunning and unique rosettes and shrub habit of Aeonium are combined with the hardiness of Sempervivum to create vigorous hybrids in a range of completely new and unique natural colours. Endlessly versatile, these specimen succulents are sure to draw everyone’s attention whether they are displayed in a patio pot, used as gap-fillers in an exotic border or planted out in a rockery or gravel garden.

Semponium ‘Sienna’ boasts perfectly geometric rosettes of pointed, bright red leaves surrounding a lime green centre; jewel-like colouring that intensifies in strong sunlight. The young plants will soon branch out to form superbly bushy multi-headed specimens that are hardy down to around -4C. A horticultural landmark, this outstanding brand-new cultivar is a must-have for any collection! Height and spread: 40cm (16in).

Pot up plugs plants and grow them on in warm, frost free conditions. When all risk of frost has passed, gradually acclimatise plants to outdoor conditions over 7-10 days before moving to their permanent positions. Grow Semponium plants in well drained, sandy or gritty soil in sun or light, semi shade.

Whilst Semponiums are hardier than Aeoniums, and are thought to be hardy down to around -4C, in colder parts of the UK they are best grown in pots where they can be moved to a greenhouse or conservatory during particularly cold periods.
