They are grown for their foliage and flowers, they have finely divide, pinnate to 4 pinnate, fern like leaves, and bear compound umbels of tiny, yellow, green, purple or white flowers in spring and summer. Suitable for a rock garden, raised bed, or for naturalizing in a wildflower garden.
Grow in moderately fertile, sharply drained soil in full sun.
Prone to downy mildew, rust, and a few leaf spots.
L. dissectum – This low growing, perennial from the Rocky Mountains grows 6-16″ tall and 8″ wide. It produces triangular, 2 to 4 pinnate, fresh mid green leaves, 6-14″ long, composed of oblong leaflets. Bright yellow or purple flowers are borne in rounded, compound umbels, 1 1/4-5″ across, very early in spring, as the leaves develop.
