American chestnut from the surviving tree and nasturtium seeds forming from last week’s cut flowers. The tassel at the top of the chestnut is on both American and Chinese chestnuts. It’s actually the remains of the flower’s pistol, through which the pollen travels into the ovary during pollination.
The green nasturtium berries are also seed-bearing ovaries ( fruits), which grow in threes and then split apart and fall to the ground as the flower dries up. These are the vitamin-packed caper-like seeds that early sailors snacked on to prevent scurvy. I ate one of these green from the garden. It was super peppery with a nasturtium undertone and a texture something like a raw green pea. Will try soaking one in vinegar first.
I think the chestnut looks like a World Was 2 canteen in a brown velvet case.
