I am suggesting the the Seniors would get some pleasure in growing from seed rather
than having seedlings ( which are quite expensive and do not last long!)
I have sent an online order to The Seed Collection" for some seeds ($17.00) :

Kale
• Tomatoes
• Chilli
• Lettuce
• Chinese Broccoli

I also suggest purchasing a large $6.00 bag of Coriander seeds from one of the local Indian shops
These can be also divided into smaller Ziplock bags ...
