Does anyone know what the hardiness of this plant is? I started a plant from seed this year and it so far has survived multiple frosts and a snowfall last night... do I need to bring it inside for the winter?

I am not as cold as you are but apple mint is hardy here and spreads like most mints.
We have had a frost and freeze in most of the gardens I tend and the apple mint has not been affected yet.
I have not tried to over winter mints inside before , but have had very little luck, I think they require too much light for my house conditions.

If it doesn't make it let me know I will send some roots in spring.

I have grown pineapple mint in the past, on Long Island in N.Y.
But here is what I found on Wiki:
https://en.wikipedia.org/wiki/...
Hope this helps.

Thanks, Cinda -- mine is growing in a pot, I think I'll try cutting it back quite a bit and putting it in a south-facing widow in a cool room; our "shop" stays around 55F during the coldest part of the winter and has the only suitable window (all of the other windows in the house are low-E glass, which doesn't seem to let enough light in for most things), so I'll try it there -- along with my rosemary plants that have happily spent the last 3 winters there. It started easily from seed, so I'm not too worried about "losing" it.

Gardeningal, I appreciate the link, but unless I missed something in the Wiki article, it doesn't really say how hardy the plant actually is -- ?

Interesting read
i did not know pineapple mint was a form of apple mint
looks different and the white flowers and such
anyway I have purchased pineapple mint twice and it has not survived the winter in ground in my garden ? so I don't know why ? If they are the same genetically (name ) Plant

That does seem strange... I like the variegated leaves on the pineapple mint, might have to give that a try next year!

Cultivation: Grow in full sun for most compact habit; tolerates some shade. Prefers moist, well-drained soil but adaptable to other soils and fairly drought tolerant once established.

Pinch back stems regularly (or harvest for use in teas and baking or as garnish) to encourage a bushy shape and promote new growth, which has the strongest fragrance. If stems with plain green stems appear, clip them off—all the way back to their starting point—to discourage the plant from reverting to its parent, the all-green M. suaveolens, or apple mint. As plants become woody, remove them to allow younger plants to fill in. Deer resistant. USDA Zones 5–11

That's as much as I could find for ya!

I'm pretty marginal for zone 5 -- but might try sticking it in the ground in my unheated hoop house for the winter, instead of bringing it in.

Thanks!

Yeah, that's pretty odd, Cinda. The world of variegated plants.
I cross referenced* and they are one in the same but for the variegated leaves, (if I read that correctly).

Oh well, bedtime.
'Nite all.

This site : https://www.mountainvalleygrow... , which has quite a nice selection of herb plants, lists apple mint as hardy to zone 5 and pineapple mint hardy to zone 6; so, although they seem to be the same genus and species, maybe somehow the variegated trait makes the pineapple mint less hardy ?

Great, I will look into that site. Thank you.

In the past, I've heard that the lighter/white varieties of plants are the weaker ones....
I don't know. I never really paid a lot of attention to that.
Also, I see that you wanted to bring the mint into the house or put it into an unheated hoop house. I would try both, can't hurt.

Btw, that site is fun! I could get into a lot of trouble....

That's pretty much what I thought when I started looking at it!

Apple is one of my stronger and more robust mints here in Zone 8. Others I have are chocolate, mojito, orange, and spearmint. The second ones rather struggle along, but the apple mint is a definite keeper. I have these planted in the gravel of my driveway next to my barn, where they get no extra water and no particular care, other than occasional weeding and cutting back. Morning sun only so sometimes they lean outward.

Have you guys tried growing nutmeg?
Either in your home or even a hothouse? I was thinking of trying my luck. Could get pricey tho.

I am still looking through the Organic Mountain Valley Grower site. (Thank you Weedwhacker)! I can't wait to get the perfect spot to plant some different mints and oregano. Just let them go wild. I used to have some, but we've moved from that home. : (

I have a little start of apple mint I think? I have it in a large pot with my tomatoes. I think I will mulch it to help it to live through winter, I am in zone 8b. I have chocolate mint which dies back every year but regrows back in spring.
Would anyone like to trade either a plant or some roots of Orange mint, Pineapple mint, etc. Mints for something you are looking for?
Thank you so much for your help
