Penta- "Giant" Red Pentas (Old fashioned) (Florida-Friendly)
Pentas lanceolata
Unlike the short hybrid penta, "Giant" pentas can bloom for years. Something happened in the hybridization process that has made the shorter penta more susceptible to a fungus, killing them often within the first year. Not so with this taller, great-grandparent of what you can find at the box store's, and most nurseries. Cutting back often will produce more blooms.. Protection for Pentas is equivalent to that of every other warm-season perennial. The most common pest is spider mites.

“All items arrived quickly and well packaged. I usually expect to have one or two live items out of a batch, but they are all thriving. I couldn’t be happier!”

“My live plants were packed like they belonged in Ft Knox. 😂 They really were packed beautifully. Only one plant, a bee balm, is questionable but signs that it will recover are happening. All in all I am thrilled with my plants and seeds. Some of my coreopsis have already sprouted!”

“I’ve ordered seeds from Whitwam Organics 3 or 4 times now. I love the simple packaging, clear planting guidelines, and variety they offer. Great germination rates!! The bare root plants I’ve ordered have come healthy, so healthy that the wild rabbits always approve of my menu upgrades! 😂🐰”
