I have been growing some cress in my greenhouse heated, but to day we brought a pack from a supermarket, i do use the plastic container for my cress growing, so now have 3 containers.
What i can not make out is on the pack it said 80% rape seed and 20% cress seed.
What's rape seed, do i need to get some and mix with my large packet of cress seed and how come the supermarket cress looks better than mine?
Is there a nack to growing good cress?

Have a look at this:

Mustard and cress are the traditional addition to an egg sandwich.   One seed should be spread on wet kitchen paper four days before the other.  But I can never remember which seed gows on first!         Cheers,      Tony.

Cress first, mustard later.

I'm liking this.

I always remember mustard & cress as a kid, but hardly see mustard these day's.

Didn't know the cress/rapeseed mix.

Rapeseed is a member of the brassica family, grows in fields with yellow flowers for vegetable oil production.

Also found in bird seed !

Salad rape germinates and grows much faster than true cress which is, presumably, why most of the 'cress' sold in supermarkets is actually rape. I prefer the taste of cress but if you want a quick fix sow rape seed.

I suspect one of the reasons you don't see much mustard these days is because it's a less profitable crop than some others. Hence the reason for growing our own.
