Not recommended for growing in USA - Zone 5a regions

  • Sow in garden, or start in seed trays. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 68°F and 95°F. (Show °C/cm)
  • Space plants: 55 inches apart
  • Harvest in 21-25 weeks.
  • Compatible with (can grow beside): Feverfew, Coriander, Nasturtium and Hyssop
  • Rosella bud

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.

Full grown rosella bushes looking very healthy, and then suddenly wilting and dying for no visable reason. They were just starting to flower and some very starting to set fruit. Any help would be appreciated.

are Rosella plants able to be kept growing for a second season, our crop this year of four plants are around four foot high and seem extremely sturdy and just starting to fruit now.April, if so do they need to be pruned back to ensure a second crop.

I just read a story about a farmer who said you should never plant Roselles in the same place as last season, they dont do well for some reason
