What's so wonderful of Mayleen is its vanilla scent..I love it.
Pirl, I have it growing on a wall now that is'nt so big (9ft x 6ft) also. The space might be a little taller for it, but I find it not rampant and very easy to control. After flowering during the season I trim it a bit to keep it tidy. It keeps reblooming a little after the first flush in may.
