Blue Moon Blue Moon has classic Tea-shaped blooms of pale lilac borne on long, almost thorn-free stems. It is certainly the most popular of the ‘blue’ coloured roses for it grows vigorous and tall and has a wonderfully strong, sweet fragrance. This rose is a must for flower arrangers because of its unusual colour, tall stems and great fragrance. A Hybrid Tea Rose bred by Tantau of Germany in 1964.
