A short freeze should not do it in. They can take awhile to get back up to par, but 2 yrs seems excessive. They do like warm/hot temps, and a cool soil might be a problem. Are there others in your area?

Sounds Gary,like the main stem is dieing and now is pupping a new generation.If the main stem doesn't die, it still might not ever regain vigor.You might be better off next spring chopping it down and let the roots feed the pups..and then decide if maybe keeping just the best pup.
I know you know that's not based on standing there in person seeing the plants condition up close.

Gary, sorry to hear about your Traveler's Tree. I hope it makes a comeback. I just have a quick question--I can't remember if you are growing H. latispatha 'Red' in your garden. If so, how did it do for you? (size, flowering, hardiness, etc). Thanks.

Mike

thanks for all your input.
there are very few in my area,but i have another one on the other side of my yard,which is doing great,although only 4 feet,it was un effected in the cold snap,and its roots are in full sun,so hard to tell if the cold or lack of sun on roots are factors in my other plant
mike,will try to send you an email,but if it fails,
red lat,gets to about 8-9 feet for me,and blooms like crazy.
dug up most of mine to make room for other species,but still have 1 clump
