tree flowering is so short term ... and in my z5, so early .. that they are usually done.. before the hummers come north .... if it were me.. my best suggestion .... plant any tree for other reasons.. and hang a hummer feeder from it .... otherwise.. you would also be better served by planting a number of shrubs.. that flower over a longer period, so that once they stop into your garden.. they have a reason to stay ... my elderly neighbors have the feeders... no kids.. and the bee/wasp thing .... the hummers cruise my garden for any and all flowers .. after getting sugar from the feeders .... they really dont need specific flowers to come to your yard ... i have also found the smallest nests you would ever believe .. good luck ken

I've given away lots of seeds, and I hope that it will help the butterflies and also make people happy seeing them. I have only enough seeds left for one person. I'm out of some of the seeds, but I do still have a pack of each of the following left: Cardinal Flower Tropical Milkweed Swamp Milkweed Vervain (Verbena hastata) Ironweed (Vernonia altissima) New England Aster Smooth Blue Aster Pink Hibiscus If there happens to be someone left on this forum who I haven't sent seeds to (lol), these can be yours for a stamped padded envelope as I said above. Please post here so others know that they're spoken for. Cathy

I have lots of Lobelia cardinalis, it self sows here and there in interesting places, and I usually transplant and expand or create another patch. Transplanting L. cardinalis is easy, however I would not try to divide a Cardinal flower as they make a rosette of foliage and my instinct says it should stay intact. However I've never tried it. L. cardinalis has been fairly long lived. If you deadhead and pamper a bit with water and compost, it will successfully make offsets each year. The original 2 pots I bought at the nursery in 2007 are still alive, and also 2008 winter-sown plant and their seedlings. I have been growing Cardinal Climber for 3 years and it has never reseeded, but have successfully collected seed. Last year the deer went to town on the CC and the MGs on my new trellis and so I constructed barriers, which allowed some recovery to the vines and decent showing of blooms. The hummers nectar regularly on CC, but they LOVE cardinal flower. I think it is their very favorite plant in my garden. Here's a pic from last year -

I love hummingbirds! Well done Ron! :)
