This frost tender annual grows to a height of 2 metres. It is grown for its red fruit which make delicious jam or jelly.

Rosella needs a growing season of at least 6 months warm weather so is best suited to tropical or sub-tropical areas. Can be started under glass in cooler areas. Water well and give a dressing of fertiliser when flowering starts.

Culinary hints - cooking and eating Rosella

The large flowers produce a crimson enlarged calyx.
Use the fleshy red calyx, without the green seed pod to make jam or jelly.

Does roselle grow in Edmonton as a perennial or annual?
25 May 23, Liz (New Zealand - sub-tropical climate)
Winter in Edmonton would be too cold for Roselle to survive, so treat it as an annual.

Summer brings rain - rain brings insects and grubs. Look on the leaves at night time and pinch off. Use some chemical sprays or organic mix. Any general fertiliser.

There is no planting guide for Rosella for United Kingdom. Probably not warm enough to grow.

After a lovely harverst, I cut down the plant and a few of them look like as if they are dying. How do I look after them after flowering and seeding as this is my first year. Comment for jam making, you do not have to boil the seedpods, there is enough pectin in the fleshy part to set and it is a cleaner taste. I have been making jam for years.
