Hi all,
I have (4) 10 inch clay pots and (2) 12 inch clay pots. I am hoping to direct sow some seeds in them either by themselves or in combinations. I wanted to try to keep in the pink/cherry red-raspberry red/blues & purple color scheme.

These are the seeds I am considering somehow putting together.

Nasturtium cherry rose (6-12" mounding habit)
Convolvulus Blue Enchantment (14")
Cerinthe major Purple Belle (I think I read 24")
Love in a Mist (Nigella) in blue shades (1-2 ft)
Bachelor Button Dwarf Blend (12-18" tall)

Is there any way I can make some combos of these in these 10-12" pots, or do you think I should just plant one type of seed in each pot?

Also, should I put the Miracle Gro potting soil I bought in the bottom of the pots, but plant the seeds in the seed-starting mix on the top part?

Thanks!
Phyl
