I have one lonely water hyacinth plant sitting in a small vessel of water
in the house for over-wintering it. (One of the dogs happened to develop a
taste for destroying all the rest and this one is the only survivor from
last year.)

Air temps around here are up into the mid- to upper-60's and nighttime
temps only in the 40's. (Water temp unknown; thermometer's broken.) Temps
should remain about the same for at least a week--maybe more.

Is it too early to put out my solitary survivor in the pond?
============================
Going from a warm house to temps in the 40s at night may prove fatal to you
WH. A frost will surely finish it off. If it were my plant I would wait
until the nights are at least in the 50s and all danger of frost is past.
