Nasturtiums are plants that just keep giving

From the moment they are planted in spring, they respond to the smallest amount of care (a bit of earth, occasional watering) with vigorous growth, lily-pad-shaped leaves and then, around about now, cheery and abundant blooms. Not only do the flowers look good in the garden as they scramble and tumble about, but they make a pretty, peppery addition to salads, and they can be brought indoors for an instant bit of summery colour.
