I just planted some Convolvulus Seeds, blue enchantment, burgundy, and pink in my hanging baskets too. As the stock, and pansies start to fade out mid spring, when we start soaring into the 90's, it will fill in and replace it, mixed in with the petunia's and snapdragons. As the petunias and snapdragons fadesout, I will probably put purslane and rose moss in these pots, and they should do fine through our hot summer.
