Nasturtium bud

I just love the futuristic shape of this budding Nasturtium. I have often wondered why they have that tail.
This summer I will continue my efforts to get anyone who comes to my house to eat the flowers. I haven't been very successful yet! I think they are lovely.
I often hear cries of 'Mum, you've got flowers in the salad AGAIN!' from the Conventboys. My attempts to get them to eat Chive flowers recently was also unsuccessful.
