What it provides nutrients
No reference nutritional values have been published for this plant in the Ciqual table (ANSES) or in USDA data: we'd rather not make anything up. Edible flowers are used in small amounts, mostly for color and flavor.
Key steps
- Choose a dwarf or trailing variety: it spills nicely over the pockets of a tower.
- Flowers, leaves and buds are edible: a peppery taste close to watercress.
- A solution that’s too rich produces lots of leaves and few flowers: go easy.
- Watch for black aphids under the leaves.
