there are many forms of lavenders and while many are hardy, there those that aren't. And usually the grafted types or lavenders, are probably the spanish types and may not be hardy in our zone. The blooms are larger than other types of lavenders. (I'm also in Ontario). I would suggest that you research your plant on the richter herbs website. Richter Herbs is located here in Ontario and they carry a wide variety of lavenders.

Lavenders that are tall would be a French or Grosso type and these are hardy types.

If the leaves wilt- then it's suffering. If not, its doing good. Some of the larger flower varieties can 'sleep' at night. So nothing to worry about. Just don't overwater lavenders.

Thank you for the tips, info and website. I think it was just transplant shock that was making the flowers nod at night. It's not really doing it any more. As for the variety I'll look at the website and see if I can id what I have. The tag was very generic stating only that it is lavender so that wasn't any help. Thanks again. Barb

I don't know where you are Barb, but down here inChatham-Kent , we have farmers growing it. I grew one for several years, until it got untidy, so they are hardy. The farmer's name is Korpan. They have an open house every year so you can visit, see what they have that you want. I am going to get another one, I cut the flowers off and put them in the linen closet. Mmmmm.

BTW-when a plant is grafted on a trunk, it is called a 'standard'. Roses, lilacs and other common plants are often grown as standards.

It has been my experience while living in 5b Ontario that only the English 'Munstead' lavender is hardy enough to survive that zone. I have tried several other types but no others came back in the spring.

The seeds will be evident when the flowers are dead and dried out. You will see the pods on the flower stem where each little purple blossom was previously located. Let the flowers get very dead, brown and dried out before harvesting. Cut the whole flower stalk to harvest seeds and rub stalk between your hands while holding inside a bag. Store seeds in a paper envelope labelled for a few months until very dry.

Lavender likes it dry without a lot of TLC.

You can always try bringing it in for the winter if you have a south, sunny window. Keep it on the dry side and done feed.
