Tips On Growing Kniphofia (Red Hot Poker)
Kniphofia (Red Hot Poker) is a genus of showy perennials native to southern Africa, with most species found in the Republic of South Africa.
Preferred growing conditions:
- Red Hot Pokers thrive in a wide range of soils including clay. Plant them in full sun.
- Mulch with common mulching materials in arid climates.
- Water regularly the first growing season to establish the plants. Once established, they only need occasional deep soaking in hot, dry weather.
- Deadhead the plants after blooming to keep the plants looking tidy, but they generally will not come back into bloom.
- Fertilize lightly in the fall with a half and half blend of Yum Yum Mix and good quality compost.
- These perennials are highly attractive to hummingbirds.
- Kniphofia will re-seed themselves and should be deadheaded if volunteer plants are not wanted.
- Plants are easily divided in early to mid-spring if they get too large for their space, or if new plants are needed.

Comments about High Country Gardens Kniphofia caulescens Tiffindel Cold Hardy:
If you like the flowers of the closely related aloes then you'll love kniphoias. I've planted three species/varieties of this and for foliage this wins hands down. The thing I like best about it is that it tolerates cold damp winters well even when most of the plant is buried under old leaves-though I would recommend keeping the leaves to a minimum.

USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
