Nasturtium ‘Jewel’ is a compact, small-leaf variety with bright, semi-double flowers that stand clear above the foliage. True to its name, the blooms come in a mix of vibrant jewel tones, making it a cheerful and useful addition to beds, borders, or veg plots.

SOW: start seeds under cover in pots or modules about 2cm deep during February or March. Or sow them directly where you want them to flower in April or May. If you start them in pots, make sure to harden them off before planting out.
GROW: nasturtiums like free-draining soil and actually do better in poor soil. Too much rich compost or feeding will just give you loads of leaves and fewer flowers. For containers, try using low-nutrient seed compost when planting. Keep them watered regularly until they’re settled, then they pretty much look after themselves.
ENJOY: add the peppery flowers and leaves to salads, or use the seed heads like capers. Great among your veggies or in the greenhouse — it’s also handy as a sacrificial plant near crops like broad beans to draw blackfly, and is said to be beneficial to apple trees too.
