It’s supposed to reach 24-30″ (60-75cm), but mine must not be old enough yet — it’s maybe 12″ (30cm) tall.
I hope it gets bigger, because if it doesn’t I’ll have to move it. It’s supposed to arch up and over the plants around it, not be smothered underneath!
Anyhow, I really like the brightness of the foliage. As you can see, the flowers aren’t even that noticeable with all of that variegation, and the pattern really lights up a dark corner.
This is one that I’ll have to get more of.
