In addition to repelling some undesirable insects, marigolds combat nematodes and the worm that likes to eat tomatoes.
I'm getting a medley of perennial flowers that attract hummingbirds and butterflies and some of those flowers are Jumping Jack Marigolds. I'll plant these along the front border of the dirt part of the garden.
In the large pot planter in the middle part of the dirt garden, I'll plant Black Seed Sesame flowers (and send Johnny some of the seed so he can grow these and have sesame seeds to eat every year as he won't plant anything he can't eat):
“Black Seed Sesame was first domesticated in India, cultivated at Harappa in the Indus Valley between 2250 and 1750 BC.
Single stem with oval leaves and tubular flowers are yellow to blue or purple. Grown for its edible seeds in long pods that burst open when ripe. Seeds are dry roasted and used whole in cooking or ground and used as a paste for flavor. Used extensively in Asian, East Indian and Mediterranean cuisines. Black varieties are prized in the Far East, which have a rich earthy, nutty flavor and have high amounts of protein, phosphorous, iron and magnesium.”
