American Goldfinch is a big, bold native false indigo that sends up loads of bright golden yellow flower spikes for many weeks in late spring and early summer. It is one of the most free-flowering baptisias available.
Its wide habit, about three and a half feet tall and up to five feet across, makes it ideal for filling large spaces, meadow plantings, mass plantings or as a specimen. Round seed pods follow in fall. Once established it is very long lived, drought tolerant and practically care free, and deer leave it alone.
What it looks like
Upright, lupine-like spikes 10 to 12 inches long densely set with pea-shaped flowers in bright golden yellow, rising above the foliage on sturdy stems. Leaves are three-parted with oval leaflets in medium to blue-green, forming a dense, shrub-like mass. The plant is wide and mounded, 36 to 42 inches tall and 54 to 60 inches wide. At peak bloom dozens of golden spikes cover the broad mound; round seed pods follow later.
Growing it with lavender
American Goldfinch thrives in the same sunny, lean, well-drained soil as lavender, and its golden spikes open just before lavender blooms, then its bushy blue-green foliage makes a sturdy backdrop behind lavender all summer.
Care
Plant in full sun to part shade in lean to average, well-drained soil; the deep taproot makes it drought tolerant once established. Hardy in USDA zones 4-9. Choose a permanent spot, since established plants do not like to be moved; expect a couple of seasons to settle in, and cut back in late fall or leave the seed pods for winter interest.
