Rosella fruit is best grow in soil in ur garden. As it can grow to 2 metres its restricted in a pot. Ive got bout 30 plants on the property and have just harvested the first lot of fruits. Its a great annual and this year I will sell most of it dried to make into a delicious drink. Lovely member of the Hibiscus!

Packets of Rosella seeds are sold in some garden centres in NZ. I found some on a display stand with other Aus seeds.
