Masses of funnel-shaped, red, yellow, orange and cream flowers appear with the conspicuously splotched cream and green leaves. These colourful plants are perfect for the front of a sunny border or for filling a large pot on the patio. One of the easiest annuals to grow, nasturtiums put on a long display throughout summer and autumn.

Both the flowers and the leaves are edible and have a sweet, peppery flavour, and when planted in the kitchen garden they will help repel whitefly while attracting blackflies away from the crops.


Avoid overwatering or over-feeding (once per fortnight with a diluted liquid feed is ample) to avoid producing leaves at the expense of flowers. Requires minimal maintenance though a check for caterpillars and blackfly will help reduce incidence of defoliation. Dead-heading regularly will also encourage an even better display.


Soak the seeds overnight and then sow an early crop under glass in good seed compost, covering lightly. Maintain the temperature between 13-16°C (55-61°F) and water when necessary. When large enough to handle, pot on or acclimatise slowly and plant outside after all risk of frost has passed. Alternatively sow directly outside in mid to late spring.
