FAQ

Why won't my shell ginger flower?
It flowers on second-year stems: if you cut them every winter, or cold stops them maturing, it won't bloom. In a pot, give it warmth, humidity and time.
Is shell ginger frost hardy?
Barely: the foliage suffers below 5-10 °C; in cold climates grow it in a pot and shelter it in winter, or mulch the base well.
