One of my all time favourites - 'Renae' - a repeat flowering climber that has small double blooms, and a gentle fragrance. Vigorous growers, they can reach more than 12 feet in height and two have been planted to grow up the front of my house, then along the roof-line. This one is now about six feet tall and growing strongly. The other one is only 18 inches tall, but valiantly smothered in blooms.
This is really the true colour of 'Altissimo' - a French bred climber with large (4-5") flat blooms. I'm growing it on a trellis in the hope in time it will hide a neighbour's ugly outbuildings!
Obviously not a rose, but Nigella or Love in a Mist - a great annual plant that self seeds, good for filling in spaces, but a potential nuisance if allowed to go too wild.
