If you've cut off the tips of the plumeria it may take the entire season to recover and grow new tips... I wouldn't write it off as dead yet :)... glad you have some inflos... I have none, but my mom just planted her Puu ka hea (sp?) in the ground and it has an inflo, I'll post pictures as that one blooms
Linda, make sure you show us pictures of your flowers when that inflo blooms
