Answer: Heuchera Citronelle is a perennial in gardening zones 4-9. You are in zone 5 so it should be fine. Heuchera Citronelle grows about 10" tall and 14" wide and is sun tolerant. The foliage has a citrusy smell which, if crushed to release the fragrance, will repel mosquitoes. I wouldn't count on it to keep mosquitoes at bay, though, because it only works if the leaves are crushed, and for only as long as the fragrance is strong.
Best wishes with your garden!
