Spinach and leaf beets

My Spinach v Leaf beet/Chard comparison has started.

Just sown 16 seeds in modules of the following:-

Spinach  - Amazon F1 (packed Nov 2018)
Spinach -  America (sow by 2017)
Spinach - Giant Winter  (undated)
Leaf beet - Perpetual Spinach (sow by Sept 2016)
Leaf beet - Rainbow Chard (sow by Sept 2020)
Leaf beet - Rhubarb Chard "Intense" (packed Nov 2018).

EDIT - Found some New Zealand Spinach seeds so I'll sow them tomorrow - apparently they need a soak first.

If the old seeds fail to germinate, I'll resow with more recent seeds - as I seem to have plenty!
