Just be aware that dahlias may not be hardy in your area (they're classified as "tender" here) as they are a tuber and not a bulb. They will most likely need to be dug up and stored over the winter. Caladiums and Elephant Ears are tropical bulbs and NOT hardy except in zone 10 (south Florida) so you will need to dig them up in the fall. Anemones and glads are hardy, can be planted in the spring, but may not flower until the following year.
A couple of things are confusing though. Clematis is NOT grown from a bulb. And pavonia can be either a bulb (Mexican Shell Flower) or a plant (related to the hibiscus) but neither are anything like a lilac.
NP has elephant ears that come back every year big, full and tall, and she's in Delaware. I have some elephant ears already that I got from my office that were doing just fine there. They dig up the landscaping every few months and toss everything, so I snagged the EEs and brought them home. They die back, you mulch 'em, and they come back the next year. :shrug: But I bought a few more because I want to fill in more of my yard's empty areas.
The Pavonia I have is called "tiger flower". I just looked at the picture, liked what it looked like, and bought it. It's not like a regular lilac bush/tree.
Here's a link to what they look like. The one's I bought are the fuschia colored one in the picture.
The clematis is actually "plants" in the bag. I just used the term "bulbs" as a generic reference. The gist is that I have a LOT of stuff (bulbs, plants, tubers, etc.) to plant, and once they come in, the yard will look amazing!
