i had 3 comfrey plants 2 already died

the last isnt doing well.

not sure whats wrong. the yard is farily low, and they seem worse when we get a lot of rain.

i think its rained 10 of the last 14 days.

is it the "type" ?

i think its "true" comfrey. i did see it flower once.

are there other varieties that do better in high rain areas ?

Also, i am in New Orleans. we dont get much cold weather here.

its been 95F every day, 82F nights.
