Nursery contributed plant descriptions

Very hard to find, this is a PERENNIAL, densely matting and highly desirable dark purple Viola cornuta. Even better, the blooms are rather large - about 1” across and are well displayed atop upright stems to 6” tall. Here in USDA zone 10A (Sunset zone 17), I find it prefers part shade so it's perfect for growing under roses, trailing over the front of a partly sunny raised bed or used as a filler between taller neighbors. Slowly spreading to about 1' across, it blooms off and on year around here or Spring thru Fall in more extreme climates. Give ‘Ulla' rich well drained soil and average water and cut back any time it needs rejuvenation - it bounces right back. Lovely with green flowering Nicotianas!
