Semponium 'Diamond'

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.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
