Proven Winners
Gardeners loved the dark foliage of ‘Summer Storm’ Hibiscus, but it got too big for a small garden space. ‘Perfect Storm’ takes the dark foliage and shrinks it down to a manageable size (about half the height of ‘Summer Storm’). At 3 feet tall, it will still be the centerpiece of your sunny garden. This beauty demands a presence! ‘Perfect Storm’ has huge, 7-8” wide, white flowers with a bright red eye that radiates out the veins, with the petals edged with pink. Enjoy its blooms from late summer into early fall.

Maintenance Notes
Hibiscus love the sun and need moist, well-drained soil. Keeping these plants watered will result in larger flowers and lush foliage. Deadheading will improve the appearance of the plant, but is not necessary for continued bloom. It is best to plant Hibiscus in the garden before the heat of the summer arrives, and should be heavily mulched the first winter. In spring, cut back any remaining stems before new growth appears. Do not trim back in fall. A strong pair of loppers or a saw will be necessary to cut this plant back. Be advised that Hibiscus is always one of the last perennials to emerge in spring. Be patient, even if you think it is dead, it most likely isn't. Its vigorous growth rate more than makes up for this late start, however. Japanese beetles find these plants especially delicious.

Pinching and Growth Regulators

With liner grown plants, to encourage branching, soft pinch when the shoots are 2-3 inches long leaving 4-6 leaves on each branch. Allow at least 6 weeks from pinching until the desired bloom date. If using liners in larger pot sizes, additional pinches may be necessary.

With bare root grown plants, pinch when new growth is 4-8 inches tall, leaving 4 to 6 leaves below the pinch. Allow at least 6 weeks from pinching until the desired bloom date.

Plants grown outdoors should not need growth regulator applications.

When grown in greenhouses, spray multiple applications of the tank mixture of B-Nine at 3750 ppm and Cycocel at 1000 ppm or Sumagic alone at 7.5 ppm.

It is best to begin PGR applications about 3-5 days following a pinch and apply them at 7 day intervals, if additional control is necessary.

Pest and Disease Management

Standard pest and disease practices as stated in the notes.

Aphids, spider mites and whiteflies may be problematic, scout and treat as necessary.

Grower Tips

-Plant the crown (where the roots meet the stem) just below the media surface. Bare root plants will have woody stems that can be several inches long, these will be above the ground.

-These are heat loving plants and they can be grown up to 80 degrees, just be sure the plants do not dry out.

-High light produces better branching, more flowers per plant and shorter plants.

-Never allow the plants to wilt or lower leaf yellowing, bud abortion and lower quality will result.

-These are vigorous plants and proper plant spacing is necessary for high quality plants, do not overcrowd.

-Summer Storm is a dark foliaged plant, however, the foliage color only develops with direct sunlight.

-Bare root plants can usually be potted and grown directly outdoors in late spring. Protect the plants from extreme cold as needed.

-Bare root plants should be used only in 2 and 3 gallon containers.

-Liners can be grown in gallon or larger containers. If using liners in 3 gallon containers you may want to use 2 to 3 liners.

-In climates with very mild winters, plants may be very late to emerge from dormancy.
