Abstract
A new and distinct cultivar of winter-hardy, herbaceous, perennial, hybrid Hibiscus plant named ‘French Vanilla’ comprising a compact, upright, spreading, mounded habit of multiple, well-branched, basal stems producing flowers from the bottom to the top of the plant from late July to early September. Flowers have overlapping, moderately-rippled petals opening creamy-yellow with slightly darker veins and dark red shiny eye with leading margin folded underneath giving flowers extra strength and resistance to wind damage. The flower buds open at the apex one to two days prior to the flower opening up flat, and the petals in the bud stage are greenish-yellow. The foliage is typically three-lobed, and rich olive-green with greyed-purple coloration when young.
