Redbuds need sunlight in order to flower. Place it where it will receive at least six hours of sunlight. Eight to 12 hours of sunlight is even better but it thrives where it gets some dappled afternoon shade.
It is tolerant of pollution and is often planted along highways and streets. It tolerates a wide range of soils but not soggy conditions.
The Forest Pansy Redbud adds interest to a cottage garden, a Zen garden or an English flower garden. I like it best in a grouping on a hillside. I planted 3 together here - note the iris blooming in the foreground. I also planted yellow daylilies behind it on the slope for contrast in summer.
