Pentas – Sunstar® Lavender
Attracts: Bees, Butterflies, Hummingbirds
Dead-Heading Not Necessary
Pentas is best grown in good, moist soil, but it can tolerate poorer soils as well. They are quite heat tolerant. An application of controlled release fertilizer at planting should be sufficient, but an additional application in mid-summer will help the plants thrive into Fall.
Great in containers and landscapes. Can be used as a cut flower where it is best used in shorter vessels.
