Hibiscus – White Chiffon®
Attracts: Butterflies, Hummingbirds
Blooms in late summer. Grows in any soil unless it is either really wet or dry. Prune in late fall or early spring. Can be heavily pruned, although this is usually not necessary. Prefers medium moisture. Deciduous shrub. Fertilize in early spring by applying a slow release fertilizer specialized for trees and shrubs. Follow the label for recommended rate of application.
Great large shrub for landscape use, young plants can be used in containers but will need to be moved to the landscape as they mature. Can be trained into a small tree. This is an excellent plant for the mixed border or as a specimen plant.

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.
-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.
