How tall will a rose of Sharon be?
I have a Rose of Sharon bush beside my patio %26amp; it has grown to 7 ft. It is planted in the ground with no special kind of dirt. I do fertilize with Miracle Grow once a month and it is still blooming this late in the year. I have it planted in full morning sun but shade in the afternoon. I have had it for 3 years now. I hope this helps.
Reply:They are very easy to care for. I have two planted in my yard and I never do anything to them. The sun and the rain take care of them. They can get pretty tall, like 10 feet or so but it takes years. I have had my planted for about 3 or 4 years and they are about 5 to 5 1/2 feet tall. One is in full sun and one is in partial sun and shade and they both do about the same.
Reply:The Rose of Sharon is a flower of uncertain identity mentioned in English language translations of the Bible. The word in question is the Hebrew חבצלת ḥăḇaṣṣeleṯ, which has been uncertainly linked to the words בצל beṣel, meaning 'bulb', and חמץ ḥāmaṣ, which is understood as meaning either 'pungent' or 'splendid' (The Analytical Hebrew and Chaldee Lexicon). The name first appears in 1611, when it was used in the King James Version of the Bible. According to an annotation at Song of Solomon 2.1 by the translation committee of the New Revised Standard Version, this is a mistranslation of the Hebrew word for "crocus". Different scholars have suggested that the biblical "Rose of Sharon" is one of the following plants:





A "kind of crocus" ("Sharon", Harper's Bible Dictionary) or a "crocus that grows in the coastal plain of Sharon" (New Oxford Annotated Bible);


Tulipa montana, "a bright red tulip-like flower . . . today prolific in the hills of Sharon" ("rose", Harper's Bible Dictionary);


Tulipa agenensis, the Sharon tulip, a species of tulip suggested by a few botanists; or


Lilium candidum, more commonly known as the Madonna lily, a species of lily suggested by some botanists, though likely in reference to the "lily of the valleys" mentioned in the second part of Song of Solomon 2.1.


Today, the name is also commonly applied to two different plants, neither of which is likely to have been the plant from the Bible:





Hypericum calycinum, an evergreen flowering shrub native to southeast Europe and southwest Asia, and the plant generally referred to in British and Australian English as "Rose of Sharon"; and


Hibiscus syriacus, a deciduous flowering shrub native to east Asia, the plant generally referred to in American English as "Rose of Sharon" and the national flower of South Korea. The flower's name in Korean is mugunghwa (Korean Hangul: 무궁화, Hanja: 無窮花).
Reply:We have one that was about 5 feet tall 10 years ago. Now it is easily 16-18 feet tall. I haven't touched the thing at all except to cut out a tree that was growing in the middle of it. These are simply gorgeous plants!
Reply:Your Hibiscus Syriacus will grow between 2 and 4 meters. They are easy to maintain. They are good for zones 5-9. Since plants bloom on new growth, shaping or pruning can be done at any time; prune in late winter or early spring in northern climates.
