Rooper's Red-Hot Poker
Kniphofia rooperi
Kniphofia rooperi is a robust, evergreen South African perennial endemic to the Eastern Cape, grown for its striking autumn torches of scarlet-to-orange-yellow tubular flowers on tall stems over strap-shaped foliage - one of the last red-hot pokers to bloom and a holder of the RHS Award of Garden Merit. It fits well as a bold focal point or late-season pollinator plant in the mixed border. The honest catch is drainage: this species demands reliably moist yet sharply well-drained soil - too dry and the flowerheads abort, too wet in winter and the crown rots; heavy clay or boggy ground without amendment is a hard no.

Rooperi is adapted to animal pollination - sunbirds in its native Eastern Cape habitat, and nectar-feeding birds plus long-tongued bees in gardens - and favours cross-pollination for good seed set; it should not be assumed reliably self-fertile.
