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.

Do I cut back my rosella plant after fruiting.? Mine seems to be dying, not a single leaf on it.

I started a tray of roselle in June an I'm planting now in July. Is it too late? I know that roselle blooms when the days start getting shorter, how does this work after the summer solstice?

If there is no planting guide in the monthly planting calendar then you can not grow them where you live. Need a warm to hotter climate.

Rosella plant is looking healthy & producing fruit, but some of the upper branches go brown & leaves & fruit wither. Looks like you bleach the colour out of branch. Located Mackay Should I put copper oxychloride at ground level or another solution
