The Globe Amaranth (Gomphrena globosa) or BaiRiHong, in Mandarin, is certainly an old time favourite of mine - having grown it as a small boy on the roof top garden of my father's shophouse along India Street in Kuching.
In our garden, we have one round flower bed in the front for this plant but the seeds spread throughout the garden bringing colours to odd nooks and crannies in the garden.
There are three colours that I know of - red, pink and white. For some reason, I never like the white version so I never grow them.
The globe amaranth is relatively easy to grow, pretty hardy and brings a strong splash of bright colour to the garden. Having said that - the garden is mainly these red ones as the pink ones seem not to thrive so well!!
