Once established, Nasturtium plants take little or no care. As they spread and grow, their foliage resembles a sea of small lily pad leaves topped with brightly colored, fragrant, edible 2" blossoms. There are two main forms of Nasturtiums. The dwarf varieties will grow to 15" tall as they form nice compact clumps. Climbing varieties grow up to eight feet as they spread along the ground, but are also capable of climbing up six foot fences, stumps or other structures.
