'Diana' Rose of Sharon (Hibiscus syriacus )
The 'Diana' Rose of Sharon, Hibiscus syriacus 'Diana', is a strong upright growing sun lover reaching 5-12’ tall with giant white hollyhock flowers early to midsummer till mid-to-late fall! She does tolerate some shade, poor soil and both high and low moisture. This makes her a perfect addition to the edge of a rain garden in the sun or part shade where the soil is not soggy!
Care Factor Rating: 1 (must be watered regularly till established and does not require pruning! She does tolerate a once a year non-selective pruning to1/3 if shaping is desired, otherwise remove only the occasional damaged or dead branch)
This show stopper has an exceptionally flowering period. This is because she is a sterile triploid that produces very few if any seed pods. With this selection, there is no longer any significant reseeding issue as there might be with many other selections. She truely is a non-invasive native landscape friendly companion!
H. s. ‘Diana’ is especially lovely when planted in multiples, looking almost like a set of triplets, she can also be planted in larger numbers to create a screen or border. I particularly love this selection when used where it can be enjoyed in the evening landscape. The flowers are exceptionally large and stay open at night. She is also great for emphasizing the white accents of your home's trim as well as compliment any color pallet. This “bride white” version of this old favorite is very heat and humidity tolerant!
There is an occasional report of some susceptibility to blight, canker, rust, leaf spots. Aphids tend to cluster on new growth and can be controlled with regular hosing off with water. Scale, whiteflies and Japanese beetle are reported as occasional issues as well.
