Garden blog - kale and lettuce varieties

So these lettuce where the same you will see in previous blogs a few months back 🍃 🍃 the lettuce are really nicely established to farm a decent amount of seeds but I am worried about cross-breeding, this is something I will be looking into the next few week..

I am preferential to the butter leaf soft edged green lettuce. But also the purple lettuce but what I don't want is the multicoloured butter leaf as a result if interbreeding..

Thanks for reading guys, I have made some great salads in the past with home grown leafs and these look delicious.
