|Hibiscus 'Midnight Marvel' PPAF (25) plants
Common Names: Rose Mallow, Swamp Mallow, Hardy Hibiscus, Dinner-Plate Hibiscus, Fleming hybrid Hibiscus, or Perennial Hibiscus.
Zones: 4 to 9.
Full Sun to part shade.
Mature height 4 feet, width 2 to 3 feet.
Glossy, black-red buds open to 8 to 9 inch, deep scarlet red flowers. Deep wine purple, dissected maple-like foliage that is thick and leathery with purple foliage; grow in full sun to achieve the darkest foliage color. Indeterminate bloomer (buds at several nodes up the stem) has blooms for an extended period from midsummer into early fall. The habit is relatively compact, measuring in at 4feet tall x 4 Â½ feet wide which is intermediate in size between its parents.
Plant the hibiscus crown at or just below soil level in a moist, well-drained, sunny location. Keeping these plants watered will result in larger flowers and lush foliage. Do not over-water dormant plants, but after dormancy is broken, do not let plants wilt. Provided with organic soil (or a fertilizer application in the spring) and plenty of water. Fertilizer should not be used after June to ensure that the hibiscus flower production is not impeded by excess nitrogen. To encourage branching, pinch plants back when new shoots are 2 inches long. Do not pinch all the way back to the hardwood portion of the stem.
Hardy hibiscus begins blooming in mid-summer and will often continue producing flowers until frost. One hibiscus plant can produce hundreds of flowers, especially with deadheading to prolong the bloom period. Attracts hummingbirds and deer resistant.
It is best to plant Hibiscus in the garden before the heat of the summer arrives. Hibiscus should be heavily mulched the first winter. In spring, cut back any remaining stems before new growth appears.
Hibiscus can be used in the garden as focal point, as a border or arranged to provide an informal hedge. Some perennial hibiscus plants are compact and some habits are taller. Perennial Hibiscus plants have no severe pest or disease problems.
