Forming beautiful rosette patterns, this colourful collection of sempervivums (houseleeks) is a must-have for any garden. Native to alpine regions, they're tolerant to extreme temperatures and drought.

Enjoy beautiful deep-pink, nectar-rich flowers in spring and yellow foliage in autumn. Perfectly suited for small gardens, you'll get two bare-root trees, plus three free winter-flowering Helleborus niger.

This rare hybrid has been grafted to make a half standard lollipop form. In spring it bears huge lemon yellow flowers, sometimes streaked lime green, emerging just before the deep green leaves unfurl.
