Hibiscus sabdariffa
Considered non-toxic to cats and dogs (source: Roselle is used as food and tea; non-toxic).
A sunny south-facing window with 6+ hours, or a grow light.
Keep evenly moist — water when the top inch of soil is dry.
Needs a little consistency, but nothing fancy.
Roselle gives the tart red calyces behind bissap in West Africa, agua de Jamaica in Mexico, sorrel in the Caribbean, and karkade in Egypt and Sudan. It is a big, sun-loving annual best suited to a sunny balcony — and its young leaves are edible well before the calyces form.
About Roselle
Roselle (Hibiscus sabdariffa) gives the tart, ruby calyces behind a family of drinks known around the world: bissap in West Africa, agua de Jamaica in Mexico, sorrel in the Caribbean, and karkade in Egypt and Sudan. It is a large, sun-loving annual, better suited to a sunny balcony than a windowsill, where a renter can give it an 11-litre pot and full sun. Its young leaves are edible too, well before the calyces form.
Grow it in as much sun as you can manage. It is a big plant that needs space, a large pot, and steady feeding to perform. Roselle flowers as the days shorten in late season, which means the calyces may not form indoors or at high latitudes where light runs short. If the calyx harvest is out of reach, pick the tangy young leaves as a green instead. Calyces, where they form, come late, around 120 to 200 days.
What it’s like to grow
Roselle is rated moderate, mostly because it asks for more sun, space, and time than most container crops. The clearest disappointment is a plant that grows leafy but never sets calyces, a sign that light or the season fell short. Treat the leaves as a fallback harvest. It is grown worldwide as a food and tea and is not considered toxic to cats and dogs.
What to expect
First harvest in about 120–200 days. It asks for a little consistency, but nothing fancy.
