This is a large family of aromatic perennials. Go up one in the family tree and you have Zingiberales which include Canna and Banana plants. You will find Gingers are both tender and hardy. I will discuss the ones that I grow. The Hedychiums flower reliably year after year in my garden. Just like Forestii opposite which is flowering now 9 August 2018. It grows to about 5 feet or so. These I grow from seed and division.
The hair colour ginger came into being due a firery red ginger which was apparently likened to the personality of ginger haired folk.

The name derives from two greek words Hedys - Sweet and Chion - Snow. It is a hard CH in Hedychium.
So many Gingers to choose from with c80 known species. The plants above grow in my garden year after year. They are all extremely hardy. At the end of the year search online @ HimalyanGardens and JungleSeeds which I use regularly. You get mixed results from these suppliers. Always report back to your suppliers with good/bad results. Not all seed/corms germinate/grow and I have found that some corms may not grow for a year or two so do not throw them away eg Curcuma Longa purchased at a plant fair at Hyde Hall, took three years to grow and flower which it did in 2018. Beware that by February/March time some plant material may have sold out.
