Kniphofia hybrida 'Poco Citron'

Poco Citron Dwarf Red Hot Poker

Botanical Name: Kniphofia hybrida ‘Poco Citron’
Family: Asphodelaceae
Origin: Africa (hybrid selection)
Plant Type: Evergreen to semi-evergreen clumping perennial

Overview

A compact, heat-loving red hot poker ideal for Adelaide’s Mediterranean climate, Kniphofia ‘Poco Citron’ produces masses of soft lemon-yellow flower spikes from late spring through autumn. Bred for dwarf habit and continuous bloom, it fits perfectly into small gardens, borders, modern landscapes, and containers. Its grassy green foliage forms a tidy clump, while the elegant citron-coloured flower spikes rise neatly above, attracting bees, butterflies and nectar-feeding birds. Exceptionally tolerant of heat, drought and coastal exposure once established, ‘Poco Citron’ thrives in full sun and free-draining soils, making it a standout performer for South Australian gardens.
