I'm looking for the tithonia that grows quite tall and is referred to as sunflower tree,marigold tree and the blooms are yellow.Check my list for a possible trade.Debbie

I just collected A. incarnata Cinderella seeds.

Yes . I have had it for four years . It can grow to be 15 feet or taller . You can trim it until the Fall to keep it shorter . Mine blooms in October for a whole month or more . The bees and butterflies go nuts for it . Marcia has one that blooms earlier . I took 18 inch stems and pounded them in the ground with a hammer . Every one took . I warn people - do not water these or fertilize them ! Just slam them in the ground and stand back ! It is a pain to clean up in Jan/Feb after freezes . Once a year is not too bad though for the reward of the gorgeous blooms . On a search you will see it called Mexican Sunflower , Mexican Daisy , Bolivian Sunflower , Tree Marigold or even Japanese Sunflower ! They are all the same plant . If you call it Tithonia diversifolia - you can't go wrong . Check google images for some excellent photos .

It might set seeds, if you took the time to look for them, but it doesn't seem to drop any or spread by them. And once you've got one going, it is far easier to cut a piece and stick it in the ground. Instant plant 2 or 3 feet tall, so faster than seeds. But for sure, if you can find seeds to get one going, then that's probably a good way to start. After you've got yours started, you'll probably go to cuttings for future plants. I cut mine back to about 3' tall every year, and within 3 months, they are way over my head again. By fall, they are usually 12 to 15 feet tall and nearly as wide, so be sure to give this one a LOT of room. You'll love it! And as an added bonus, the flowers are very fragrant...smell like honey and vanilla to me. Marcia
