the biennial echium? Well, you must have given it severe shock.... didn't dig up enough roots. You have to water it heavily and stick it in shade and cross your fingers AND your toes. :o) Since I am thinking you are talking about the biennial echium, you might just buy another.

i would keep it in the shade.
they dont need much water[i have killed 2 already!]
it will recover if you did get enough roots.!
