Also called Egyptian star clusters, this versatile annual does well in sun or part shade. For very bright shade, pentas are an excellent choice. These summer bloomers come in a variety of shades, including lavender, red, cherry red, pinks and white. The new Butterfly series is a more compact plant.
But all pentas attract butterflies, hummingbirds and bees to their nectar.
They want good well-drained soil. Pinch back to promote flowering. Some years they may make it through winter in a protected spot, but generally we treat them as annuals to feed the wildlife through the summer and the fall migrations.
