wayside gardens carries them. i got mine from gardener's supply company online.

You know, I would honestly suggest that you look for some other kind of tree. Miss Kim are still not reliable bloomers here, no matter what any advertising says. I would think after this winter we've had that they aren't going to do well since we have not had consistant chill hours.
I worked in Brookhaven for a few years, and there was a home with a line of Miss Kim lilacs. In three years they bloomed once, and it wasn't significant bloom. Not even any scent.
Sorry, I don't mean to rain on your parade (I'd love lilacs myself), but I know you've put much work into your garden and so you might want to plant something that will work as hard for you, as you do for it.

Is there any kind of lilac that does work here? I'd really love to have one in my yard.

I bought Miss Kim 2 years ago, I got blooms that first year it was in bloom when I bought it, had hardly grown and not seen a bloom since. I may have to offer them to someone further North in the fall.

ok,so I am no longer looking for Miss Kim lilac, but i need ideas for a replacement! The site in in mostly sun and is between a pathway. Ideas welcomed! I had wondered about tea olives? I guess i am really looking for something frangrant.

I have a tea olive right next to my front door step. Blooms twice a year usually fall and early spring. The frangrance does waft

Check out vitex. It has lavendar blooms similar to lilac (sort of) in the spring. And often reblooms. It's a pretty little tree.

Sugarhill, your vitex blooms in the spring? Mine always bloomed right with the crape myrtle and they were spectacular. The main problem I had with the vitex is that the foliage looks too similar to marijuana, and it has a foul odor 9the foliage, not the flowers, which have no odor or fragrance).

I think different vitex bloom at different times. I am trying negundo, and I think it blooms several times and starts early. Shrubbier than the species.

There are also gardenia, and think about butterfly bushes. Same "look" as the lilac in many ways as you can prune it any way you like. My pink delight is lovely and lightly honeysuckle fragranced. You get a very long season of bloom, and three together would really make a lovely scent.

OH NO! My Miss Kim made a TOTAL liar out of me. I went out to weed and mulch them and "think" about digging them out for fruiting plants and I saw them, the beginning of small blooms! This is the 3rd year and I recall saying now first year they sleep, second they creep and 3rd they LEAP. Well maybe I will give Miss Kim another chance! Sorry I spoke to soon for my Miss Kim!

For old-fashioned fragrant lilacs that bloom in warm climates, look at the Descanso Hybrids. I haven't tried them here yet as we get plenty of cold up here in north Hall, but they were developed right down the road from my old zone 9 garden in Southern California and are very nice. Here, my hyacinthaflora 'Excel' is just about to bloom for the first time, so we'll get to see how we like it.
