Thrift
Deep pink Armeria maritima flowers
Armeria maritima is at home on cliff ledges and rocky outcrops. This plant is a born survivor and keeps its tufty leaves all winter. There are cultivars with deeper pink flowers, but the wild species is the prettiest.
Poppies
Pale yellow flowers of Japanese poppy Papaver nudicaule
The little Japanese poppy, Papaver nudicaule, is easy to grow – sow it direct or in modules. It's a short-lived perennial and will self-seed. Alternatively, try orange California poppies (Eschscholzia californica). Flowers May to June.
Auriculas
Purple-petalled, yellow-centered flowers of Primula auricula
Tougher than it looks, Primula auricula is a mountain dweller. It has leathery leaves to withstand rough weather and extremes of heat and cold, and deeper roots than many of its relatives. Flowers from March to May.
Rhodohypoxis baurii
Bright pink blooms of Rhodohypoxis baurii
Although it needs dry winters, rhodohypoxis is a delightful South African bulb that should be happy in the well-drained conditions of a roof. It spreads by underground stolons to form large, vibrant clumps. Flowers June to July.
Saxifrage
Pale-pink flowers of Saxifraga 'Winifred Bevington'

Saxifraga 'White Pixie' is an evergreen alpine plant that produces pretty sprays of white flowers. It's best planted in sun or semi-shade. Flowers May to June. You could also grow 'Variegata' or 'Freckles'.
Kate Bradbury says
If your shed has a pitched roof, then it’s likely one side will get more sun than the other. Choose shade-tolerant plants for the shadier side, or install a mirror to reflect sunlight onto the roof, enabling more sun-loving plants to grow.
