Description:
Costus guanaiensis, also named
Spiral ginger, can grow to 9 feet tall in frost-free areas. It is native to
tropical regions of South America. It’s related to the gingers and was
originally part of the Zingiberaceae family, but now the Costus species have
been reclassified into their own family, Costaceae. As with most gingers, this
plant is easy to grow with virtually no pest problems. Spiral ginger is a tall
and handsome landscape plant with large green leaves with a yellowish side, up
to 20 cm long or more, about 4-6 cm wide, arranged on the stalk in a spiral. It
produces spiralling stems of magnificent white, pink, and yellow flowers. The
flowers appear in late summer or early fall. Costus guanaiensis is
distinguished by its green bracts with green leafy appendages and large mostly
white spreading flowers. The amount of reddish color in the flowers varies.
Hardiness zones 8-11, (-10ºC/15ºF, 4ºC/40ºF) in winter. For best results, this
plant should get from 3 to 5 hours of direct sunlight daily, and be grown in
fertile, organic, moist but well-drained soil. Requires consistently moist
soil; do not let dry out between waterings. Monthly applications of a balanced
fertilizer during the summer growing season will benefit this plant. Spiral
ginger grows from thick fleshy roots called rhizomes. A single rhizome will
produce new shoots and increase to a 3 feet wide clump in the second year under
ideal growing conditions. It’s important that the rhizome be kept dry during
winter, but in spring, when growth starts, it should be well fertilized and
watered.
Germination:
Soak seeds overnight in warm water.
Plant your seeds 1/2″ deep in a mixture of rich soil. Keep warm, moist and
in bright light. Germination is faster for the Spiral ginger than for most
gingers. It could take 1 or two months, maybe more, don’t get discouraged.
