Sedum album
White stonecrop (Sedum album) is a ground cover plant that reaches 10 cm × 50 cm after ten years. Light: full sun, part shade. Hardy down to -40 °C. Drought tolerance: high. Non-toxic to dogs, cats and children. Sold in local shops from about CZK 49.
An evergreen succulent whose tiny cylindrical leaves knit into a low, dense mat that disappears under a haze of white flowers in early summer. It is a good choice for green roofs, gravel, wall crevices and any lean, sunny spot where other plants would dry out. It spreads fast and even broken stems and fallen leaves take root, so it can overrun low neighbours: plant it only where that is welcome.

Ground cover plants against weeds: which goes where, and how many you need
A ground cover keeps weeds out once it has closed up: until then, usually for two or three summers, it needs mulch and weeding. Under trees and in shade, lesser periwinkle, bigroot geranium, barrenwort and barren strawberry do best; in sunny, dry places stonecrops, thymes and creeping junipers. Most perennial ground covers take 9-18 plants per square metre. The tables work out what a square metre costs at today's shop prices in your country.
Building a rock garden: stone, soil and plants step by step
A rock garden belongs on a sunny, gentle slope, in lean, free-draining soil: one third garden soil, one third coarse sand, one third crushed stone. Lay the stones, all of one kind, in layers leaning the same way and sunk a third to a half into the ground, so that about two fifths of the surface is stone. Four to six plants per square metre are enough: creeping junipers and grasses make the frame, and between them cushion perennials, stonecrops and thymes flower from March to October.
