This ivy is of the sage and mint family and is considered invasive which is what makes it more suitable for containers. I bought it strictly for foliage interest but I've heard it blooms in mid-summer. I looked up what it looks like in bloom and the flowers are so tiny as to be nearly invisible. Maybe mine bloomed after all and I never noticed.
Anyway, it's hardy to Zone 6 and likes full sun but will tolerate part shade. As always, allow for good drainage.
This is no weed as far as I'm concerned and it will be making a regular appearance in my garden.
