Aquilegia is a shortlived perennial/annual that breeds and self seeds prolifically. It is also a bit of a tart, so what you sow /plant won'tneccessarily be what you get the next yr, nor where you want it, and def not in the right colour. It is lovely in all it's forms, tho!
Are you looking for something ruby in name or in colour, and how permanent do you want it to be?
For repeated ruby colour, in a long lived plant/shrub with little maintenance,that would fit a cottage type garden I would suggest Photinia Red Robin or some of the latest cultivars of photinia.. It is a hardy shrub that can be cut back repeatedly without ill-effects,and all new growth is, I would say,ruby in colour. Of all of the plants that I can think of or have ever seen, I think this would be the most likely to fit your needs. There are newer cultivars with variegated leaves, eg,red/green, Yellow/ green, Cream/green , but they are not so reliable as Red Robin, and much less hardy.Areally good person to ask on the forum might be Verdun. he has all yr round colour in his garden. It really depends on whetheryou want flowers which are short-lived, or ruby colour all yr, or a mixture from different plants. I'll ask verdun to look at your post, I think he has the knowledge that you need.
