Walking the dogs this evening, a few hours before Vince flies north and then due west, to the cold of an American winter, we found bulrushes in flower, in this South African summer. In the States we call these reeds cattails. The species is Typha. Down here they are T. africana.
The top part is male - it makes pollen, and later fluff. The pollen can be collected and used as a flour.
The bottom part is the female (it later turn into the brown cigar shape), and I've known for a while that when green they make good eating, but have never chanced upon these plants at the right stage to collect them. I thought these were too mature, but the Edible Wild Plants group on Facebook has just disabused me of that notion.
Tomorrow I will collect some - can't wait to try them!
