Best (if any) Nepeta variety for shade?

For various reasons I am contemplating planting Nepeta plants in the 10x10 shady, well protected, medium dry area. NJ 6a zone.
I am considering online source for these plants - Lazy s's - they seem to have a wide variety - if you know that some of their varieties is better than others in shade, that would be the best....

I did notice that on their site, out past the zone listing are little indicators for full sun, part sun and part shade. That could help a little, also I noticed that on a couple of the Nepeta plants they list they specifically state that those particular ones get more floppy in the shade. The only mention I saw of one that seemed to prefer some shade was Nepeta longipes , it stated it needed full sun in colder regions. I did not read all the descriptions all that close but there are a few hints thrown in when reading close.

How much light does the area get, IF no sunlight, the Nepeta will be leggy with little flowering, BUT good light would help.
I love the Nepeta (CAT MINT) it spreads outwards and butterflies, bee's and other night flying insects love it too, moths are particularly fond of the plant, these in turn attract other flying insects that eat the black flies and the biting insects.

The most favourite type of Nepeta for me is called Munstead, it grows to about 6-8 inches tall ands has a spread of about 2 feet when planted in the right conditions.

I would amend and feed your soil well, this will help retain some moisture in the soil and let's air in also, the nutrients from the humus IF added will keep the plants healthy for a few years to come.
End of flowering season, you can cut the whole plant back a bit with the hedge trimmers, this allows the plant to keep some foliage and it protects the plant over the colder winters IF that's a problem in your area, come early spring when you look into the dead grey foliage, you will see tiny little new green shoots, if the weather has warmed up a little, it's then time to prune away the rest of the dead foliage to allow light into the new green shoots, then the plant puts out even more stems and flowers that the last year, give a fees around the root area, granules of plant food if fine, I like pelleted chicken manure, it's great and you don't need lot's of it, read the dosage on box as too much of any added feed is bad.
A good idea is to start your own compost heap/box./container, and when this heap turns into what looks like nice NON smelling brown earth, then throw this around your plants or into the beds, its a great way to feed, air and break up dry soil but it wont make your soil remain wet, you still have to water.
Hope all this helps you out a bit and you can eventually enjoy your bed of Nepeta, fill in the gaps with lily bulbs, or other flowering bulbs for a perfect bed you will love.
Best Regards.

If it is not at least half a day of sun then I would look into other plants. What is it about the Nepeta that you like?
Lamium has some similar aspects, and handles the shade a lot better.
Most plants with grey leaves are plants for the full sun, or close to it.
