It may not always bloom profusely, but sweet pea shrub, Polygala fruticosa, blooms sporadically through most of the year. Even when not much color is evident from a distance, a few flowers can likely be found on closer inspection. For some reason, bloom seems to be quite colorful now. Bloom phases should be more profuse in spring and summer. The pea flowers are soft purplish pink.
Mature plants might only get to two or three feet tall and wide, but have the potential to get larger. They are usually a bit wider than tall, with a nice rounded compact form. The evergreen foliage is slightly grayish light green. Sweet pea shrub prefers full sun exposure, but can get roasted in hot spots. A bit of shade should not be a problem. Once established, it does not need too much water.
