Kniphofia uvaria 'Glowstick'

‘Glowstick’ Red Hot Poker is a striking perennial known for its vivid yellow flower spikes that rise above clumping, grass-like foliage. Unlike traditional Kniphofia varieties that feature red and orange hues, ‘Glowstick’ stands out with its bright, uniform yellow blooms. Native to South Africa, this heat-tolerant plant thrives in Texas landscapes, offering an eye-catching display from late spring through early fall. It is an excellent choice for adding vertical interest to mixed borders, rock gardens, and pollinator-friendly landscapes.


This drought-resistant perennial prefers full sun and well-drained soils, thriving in sandy or loamy conditions with neutral to slightly acidic pH levels. ‘Glowstick’ is a low-maintenance plant that requires minimal care once established, making it ideal for xeriscaping. It is highly attractive to bees, butterflies, and hummingbirds, contributing to a vibrant, wildlife-friendly garden. While deer typically avoid it, rabbits may occasionally browse the young growth.


‘Glowstick’ grows in a clumping habit, reaching about 2-3 feet tall and 1-2 feet wide. Space plants 18-24 inches apart for best results when planting in mass or borders. Deadheading spent flowers can encourage prolonged blooming, while cutting back foliage in late winter promotes fresh spring growth. Over time, clumps may expand, and dividing every few years can help maintain vigor.


Although ‘Glowstick’ is very cold hardy for Texas, mulching around the base in winter can provide extra protection in colder regions. In areas with harsh freezes, the foliage may die back, but the plant typically regrows from the roots in spring. Ensuring proper drainage is crucial, as overly wet winter conditions can lead to root rot.
