Caulescent Red-hot Poker A handsome, architectural red-hot poker grown for its striking flowers and attractive leaves, Kniphofia caulescens is a clump-forming, evergreen perennial with narrow, sword-like, grey-green leaves. The fat ‘poker’ flower-heads, borne from late summer to autumn on tall, very sturdy stems, are a beautiful, deep coral-red, fading to lemon-yellow from the base as the florets age. The pollen-rich flowers are very good for pollinators. Caulescent red-hot poker is an impressive feature plant for sunny beds and borders and good for gravel plantings in coastal areas. Protect the crown in winter in colder areas.
