What a beautiful find at the recent Hort Park Gardener’s Day. Hibiscus Acetosella, commonly known as Red Shield. Its fruits remind me of the Roselle, and not surprisingly since they’re of the same genus and Hibiscus family.
As a shrub, the acetosella is perfect for balcony gardening.
According to Wikipedia, the leaves and flower petals are used for salads, and have a bitter sweet taste. I can’t bear to eat it. Will propagate some when I’ve more time.
