This Brent Horvath hybrid is one of the few upright sedums that I would grow for the foliage alone...very cool. This dwarf rock garden-sized sedum makes a compact 8" tall x 1' wide clump of tiny, very dissected, light green fleshy foliage. In late summer, Sedum 'Thundercloud' is topped from early June through September (NC) with a cloud of white stars hovering just above the foliage...this sedum has cute written all over it...writing is removed just prior to shipment.
