I have the following
Zebra Rush-(Scirpus lacustris tab. 'Zebrinus') × 1
Golden Creeping Jenny-(Lysimachia nummularia Aurea) × 1
Purple loosestrife-(Lythrum salicaria) × 1
Watercress-(Rorippa nasturtium aquaticum) × 1

Which have not started to grow yet, is that normal? Or should I worry?
I love in South London

My pond plants are only just starting to show signs of life.  I think they are just reacting to the cold spring we had.   I would not worry yet
