While the Red Hot Poker plant may look like it belongs in the deserts of Southern California, it actually is quite hardy and needs more water than you'd think. Red Hot Pokers are hardy in USDA zones 6 to 9. In cold areas, if you can grow an Adam's needle (Yucca filimentosa), you probably can grow Red Hot Poker. The key, though, is water drainage.
While the crown and roots are hardy, they cannot withstand sitting in soggy soils, especially in winter and early spring.
Planting in a sandy loam soil or in well-drained raised beds amended heavily with compost will be the best bet to bring your perennial Red Hot Poker back each spring.
Beside the exotic look, what attracts many gardeners to red hot poker plants is the ease of growing.
Red hot pokers have few disease problems other than the crown rotting in wet soils. Deer and rabbits seem to avoid the plants and few insect pests bother them.
