Under grow lights, keep them 4-8 inches away for 12-14 hours) to partial shade; at least 6 hours of direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute) daily for best bloom production and sturdy, upright stems. Plants in too much shade grow leggy and may not flower wellLight

drought tolerant (can go 2-3 weeks without water once established.

Showy Sedum

Sedum spectabile

Easy

Showy Sedum is a clump-forming perennial succulent that earns its name: the flat-topped flower clusters in shades of pink to rose-red, appearing in late summer and fall, are a reliable crowd-pleaser and a genuine insect sanctuary. It forms tidy mounds of blue-green, fleshy, oval leaves with lightly toothed edges that look attractive even before the blooms arrive. Mostly grown outdoors in borders and pollinator gardens, it is also a low-fuss container plant for sunny patios.
