This is one of my favorite perennials. Perhaps it's because I so love blue flowers or because it's easy to grow or since it's
native. I suspect, it's a combination of all three. This "bushy" perennial emerges with 3-4 foot stems that
develop bluish-green compound leaves. In May and June, stalks of blue flowers that resemble that of a pea (or lupine) stand
above the foliage. Very showy and attractive to butterflies. Interesting pods develop later with several hard seeds inside which
False indigo does best in full sun to light shade in well-drained soil that is loose and rich in organic matter. It makes for a
showy addition to a perennial border, cottage garden, wildflower meadow or mixed with other late spring to early summer blooming plants.
Good companion plants include coreopsis, roses, Asiatic lilies, daylilies, orange milkweed, etc. There are other cultivars of
this plant which have flower colors that range from darker indigo, white mixed with blue, yellow, etc.
Please note that deer occasionally browse this plant, so protect it if you have deer in your area.
False indigo is widely sold at retail nurseries, especially now when it's in bloom.
