Red Hot Poker - Torch Lily (Kniphofia)
Red hot pokers
are clump-forming perennials with grassy to sword-shaped, often evergreen
foliage that emerges from vigorous rhizomes. Tall sturdy flower stems bear
bottlebrush heads of intensely coloured flowers, usually in shades of orange
and red. Many hybrids and cultivars have been raised in a variety of sizes and
flower colours. Flowering usually occurs from autumn to spring, depending on
the species, and the blooms last well when cut. [1]
This
particular flowering beauty belongs to the genus in the family
Xanthorrhoeaceae, subfamily Asphodeloideae, which includes more than 70 species
that originally came from South Africa. The red hot poker is a herbaceous
perennial and it’s known to our Australian nectar feeding birds especially the
rosellas, honeyeater and wattlebirds that dine on the tall striking flower
heads between autumn and spring.
With a
range of different heights, the most common red hot poker flowers grown
in Australia for landscaping are Kniphofia Uvaria, Yellow Hammer, Lime
Glow, Percy’s Pride, Caulescens, Ensifolia, James Nottle and Traffic
Lights to name a few. From 25 inches tall for the dwarf red hot poker
Little Maid a small variety that has spikes of creamy white to one of the
tallest hot pokers winter cheer that grows to a height of 180 inches this can
only be achieved with a quality well drained humus rich soil, like most plants
these will bloom and grow best if they are well watered and given proper care
and maintenance. The evergreen pokers are fairly drought tolerant, frost
resistant, but not completely hardy against the most extremes of climates that
we are use to here in Australia. For easy care low maintenance, buy the tougher
hot poker varieties which sport distinctively narrower leaves. You can deadhead
the red hot poker flowering stalks after flowering by cutting them back down to
the crown and in late autumn primarily you can cut the long leaves by half only
to keep your hot pokers neat and tidy. These plants are best planted in spring
after the last frost if you are introducing them to your garden.
These lovely red hot fire poker plants will grow in part shade but prefer full sun with soil that has excellent drainage, they will not tolerate clay soils especially during the colder months. While transplanting create a hole that is about 20cm deep and 10cm wide. Use a mixture of 50% compost and 50% grit to plant the red hot poker plant in your garden. When planting the poker plants never cover the crown with soil deeper than 3 inches otherwise the hot poker may not flower and could even rot. Because hot poker plants flower at different times of the year it is best to divide poker plants straight after flowering preferably in the cooler months of the year. Keep the mulch away from the crown after you have divided and replanted the plant. [2]
