Semponium 'Sienna'

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.

Water moderately and feed occasionally while Semponiums are in active growth. Avoid watering between late autumn and spring while plants are dormant.

Though hardier than Aeoniums, Semponiums should be moved to a frost-free position on sub-zero winter nights.
