Great Britain, United Kingdom, British Isles or whatever name you wish to call this place, it has many areas ideal for growing roses. We are visiting Kew Gardens and there are spectacular displays of roses here and in many privates gardens as well. In Hawaii, growing roses is always a challenge. Roses are cool climate plants that do best at elevations of 1,000 feet or more. At lower elevations, insects and disease problems are aggravated. At best, roses require specific care or they will not do well.
