"Petit Posy" lives up to her name

I am growing a few "Petit Posy" Flower Sprouts this year, as an experiment. I must say, they certainly teach you patience...  So far they are resolutely "petit".

I have been in correspondence with a nice chap called David from Johnny's Seeds, who was saying that he believes that the sprouts will come on much quicker once the plants have shed most of their leaves. That must be soon, then. You can see in this picture the scars left by the leaves that have fallen, each matched by a teeny weeny sprout. They are (intentionally) much looser than the Brussels Sprout.

Up at the tops of the plants there is still a sort of "crown" of leaves. Presumably these are edible too, just like "Sprout Tops". Anyone tried them?

I only have four of these plants and three of them are a very dark purple colour, similar to "red" cabbage, but the fourth is much greener, nearer to Purple Sprouting Broccoli (below, at right).

Actually, even if these plants never produce much of a yield, they are worth having just for their photogenic qualities.

The lowest leaves are quite pretty just before they shrivel up and drop off, like this one:

 Here a close-up shot of one of the crowns, covered in raindrops:

And another, covered in frost:

And how do you like this "Contemporary Art" rendition of "Petit Posy"?
