Calendula seeds are the most unique-looking seed I have planted yet. It looks more like a dried up part of the flower that has curled back upon itself, revealing a spine with a double ridge. I am starting some today and don’t know whether i should try to fit two to a hole, or only one. […]
The first time I grew sweet potatoes, it was from some store-bought tubers that started sprouting. I was so happy I tried it. It’s a beautiful ground cover with purple fluted flowers, and produced tubers that I harvested in the fall. They were a little fibrous, so I have to research what caused that, but […]
