experiment

last year I saved seeds from the flowers I grew, marigolds,viola,pertuna, and none of the saved seeds have given any shoots yet,but the ones that I have bought are showing shoots, So I'm binning the planted saved seeds and replanting the same with bought seeds to see if there's any differance,

I know Marigolds are usually reliable as I have done this myself, mainly bcause Marigold seeds are so easy to collect/sow given their shape. Give them a little longer Tom, you never know.

yea i think your right VG, I've bought some anyway so I'll plant them as well, I've plenty room for seed trays, and don't call me shirley,   

I have a shamrock grown from a cutting about 7 years old, this year it has dropped seeds so I have planted em, no signs as yet.
