Kniphofia 'High Roller' PP32295

Common Name: Red Hot Poker

The sky's the limit on this tropical looking plant! Coral orange flowers open creamy white on perfectly formed spikes. The beautiful bicolor flowers are produced above a large clump of foliage and blooms for many weeks beginning in early to midsummer.

This plant may look exotic, but it's hardy to our Michigan zone 6, heavy snowfall winters, possibly hardier with winter mulch and protection.

Commonly called Red Hot Poker or Torch Lily for their tall flower spikes. These South Africa natives offer tremendous garden value by combining grass-like foliage with tall flower scapes. An excellent perennial for the middle of the border.

Kniphofia is a sun lover that likes it hot and dry, though a good supply of water is appreciated when blooming. It can be grown in any well-drained soil.

Kniphofia is evergreen in mild regions and herbaceous in cooler zones. In both areas, it will benefit by having its leaf tips trimmed in the spring to stimulate healthy, new growth. In zones 4-6, the foliage can be tied up over the crown of the plant in the fall to exclude water from settling there and freezing, which would be deadly.
