Gardeners' Notes:

The BIGGEST Hibiscus flowers I have ever seen. They regularly get over a foot across and have a bubblegum pink puckered petal. The plant blooms much longer than many other cultivars that I have tried out and as far as pink goes, it is by far the best due to flower size and prolific blooming. Can often rebloom after initial blooms are gone.

Note: currently discontinued by supplier Walter's Gardens.

First year growing this cultivar . Has doubled in size since I have put it in its permanent home . I will post pictures as soon as they bloom. Hopefully its as beautiful in person as it is in picture . So far it does need higher than average watering needs but perhaps it is because it is in a large half whiskey barrel planter.

The blossoms are huge, and a very pretty pink color. I wasn't sure how it would do in my garden because I planted it in a somewhat shady spot. But it handled the shade just fine. It bloomed for a surprisingly long time - from July all the way through late October.
