Hot and Cold is a bicolor red hot poker with tangerine orange buds that open to creamy white flowers. The upright spikes bring drama to a sunny border, and rebloom extends the color late into the season.
It grows about 2½ to 3 feet tall and 2 to 2½ feet wide. The grassy leaves contrast well with bold-leaved perennials. It is hardy to zone 6, or zone 5b with winter protection. Hummingbirds visit often, and deer and rabbits seldom bother it.
What it looks like
Club-shaped flower spikes with tangerine orange tubular buds at the top and creamy white open florets below, giving a sharp orange-over-white bicolor effect. Spikes are held on stout, bare, upright stems above a clump of long, arching, grass-like green leaves. The plant grows about 30 to 36 inches tall in flower and 24 to 30 inches wide. At peak several two-tone torches stand above the fountain of foliage.
Growing it with lavender
Red hot poker likes the same full sun and sharp, lean drainage as lavender, and its upright spikes make a bold vertical contrast rising behind mounds of purple lavender in summer.
Care
Plant in full sun in well-drained soil, lean to average; it handles drought once established but will rot in soggy winter soil. Hardy in zones 6-9, and in colder spots a winter mulch and a sheltered, well-drained site help. Cut spent flower spikes at the base to encourage more blooms, and leave the foliage standing over winter, tidying it in spring.
