[Okay, I clearly don't know how to spell hyacinth].

Approaching my first spring (pond went 'live' last September) -- I put in
some water lettuce and hyacinth in September. The water lettuce is all
gone - don't know where it went. The Hyacinth is all shriveled up, but
bobbing around here and there.

Should I throw it out and replace it, or will it come back from the
half-dead looking plants?

In Zone 10b (Coastal Southern CA), when should I expect to see signs of life
with this, and my water lilly?

Thanks!
