Sempervivums, the iconic houseleek, are working their magic and are bang on trend as the must-have plant for 2021! Sempervivums form rosettes of colourful, evergreen, succulent leaves and are low growing, making them extremely popular as a living carpet of green and an ideal candidate for green roofs and living walls as they're recommended as an ideal plant to help adapt our gardens to climate change. Also known as hen and chicks, sempervivums are drought tolerant and will grow in the narrowest of cracks - hence their common name, as they were once used to plug gaps in leaking roofs. Very much a 'plant-it-and-leave-it' type of plant - easy to grow and a doddle to maintain, fully winter hardy and produce multiple new plants every year. As a bonus during the summer, the mature rosettes throw out spikes topped with star shaped flowers which insects love, plus they produce offsets, or new plants, every season that are simple to separate and grow as new specimens.
