A friend of mine gave me some seeds of a pink morning glory. He collected the original seeds 25 years ago and has been raising them ever since. I have looked all over the internet to figure out which variety this morning glory may be. The plant has pink flowers about 2-2.5 inches across and they look like the flowers of 'Crimson Rambler', but the vine only grows 3-4 feet long (Crimson Rambler grows 8-10 feet.) Any ideas on the variety, or do I have an "extinct" cultivar?
