Just to give an idea how large these get... this was taken the end of October a few years ago and it's 4' across. It's a single plant in a 12" container with a few other plants in it. I might have trimmed the bottom of it once in maybe August and that's it. It's my favorite allysum because of its size, scent, and how long it keeps blooming well into fall.
It's a Proven Winners plant, most places that carry Proven Winners will have it every spring. Their White Knight, Blushing Princess and Violet Knight Alyssums also are very good, but Snow Princess is always the biggest grower.
