Heuchera Cylindrica Alpina

Although a close relative of the showy, modern cultivars, you would never guess. This is a tiny alpine, small enough for a trough, making a really low mat of dark green, leathery leaves, and unusually for a heuchera, the disproportionately large flowers are showy, arising in dense spikes of tubular, yellowish flowers, standing well above the mat of foliage. It is perfect for any small rockery or container but prefers very well-drained soil that must not dry out.
