Pentas White (Pentas Lanceeolata Graffiti White) - No matter where you live, you can grow Pentas seeds. In frost-free zones, Pentas will live as a perennial, and in colder zones, Pentas plants will be annuals giving lots of colorful, nectar-rich blooms. This Graffiti white Pentas is striking in the flower bed with low-growing, mounding, compact, uniform plants. Pentas plants are also well-suited for containers. Known also as Egyptian Star Cluster and Star Flower, Pentas are ideal in a hot, sunny location.
Grow Star Flower from Pentas seeds indoors in late winter. Use a quality seed starting mix and press the flower seeds into the mix. Do not cover the Star Flower seeds. Place clear plastic or glass over the starter tray or pots to help hold in moisture. Keep the flower seeds moist but not saturated. Place the trays in a south facing, sunny window for germination. As the Pentas seedlings emerge, remove the plastic and keep them in a bright, well-lit location. After hardening the seedlings for 10 days or more, transplant outdoors after frost season is over. Pentas flower care includes deadheading the spent flowers to promote continual blooming. Apply a fertilizer each month during the growing season. If the Pentas Egyptian Star Cluster plants are being grown as perennials, cut them back each fall.
