Natalie - I caught that after posting it and had to find the photo on my computer. Photo added to my post above which was taken today ... rather tonight. I typically plant 3-4 seeds per cup of a specific cross. I like to keep the siblings together when sowing them and then later split them up when planting outside. I always hold back a few seeds of each cross .... Murphy's Law ... you know!
Any seeds I obtain from others is usually 5-8 seeds per cross, so sowing 4 is a good round number. Then I get 3 to germinate. Always seems to be 1 in each cross that does not germinate. No idea why.
