Nasturtiums may be known as “nasties” to gardeners, but they are actually one of the nicest garden flowers. However, to make them grow, sometimes you have to treat them nasty! A little sandy soil, a smidgen of sunlight and water, and soon you'll have more nasturtiums than you know what to do with. (Hint: Eat them on a salad for a sweet, spicy treat!) Delightful blooms of bright orange, red and yellow trail up black knee socks.
