Could anyone tell me if Lemon Thyme would survive a Northern Maine winter(zone 3/4)? I was thinking of using Lemon thyme for a border in my front garden I just love the smell and the plant looks nice too.
Lemon Thyme is a vigorous, low-growing herb that is an excellent edging or container plant, as well as a culinary treat! Zones 5b-10. Can survive winters in 4b & 5a with winter protection with a 3" pot.
This is base on what I have searched from Google.
Microclimates, like over the septic tank or next to the house, can do a zone bump. It's always an experiment with some successes and some failures. Just make sure to have very well-drained soil especially for winter in any location you try.
