Magical Anemones?

[CuttedUpPear]

Yesterday I found some lovely blue Anemone blanda growing in my veg patch.
Now I've grown these for people before but we have always bought corms; I've never known them to spread widely. There are no others in my neighbours gardens and I've found four growing in the garden near the house as well. We live in a rural area and there are hardly any passers by the garden.

Weirdly it looks as if the ones in the veg patch are planted in a grid. It could just be that I mistook anemone corms for garlic bulbs last autumn but I doubt it very much.
Has anyone got any idea how this could have happened?

Or it it a message from aliens do you think?

I planted some at the tail end of last year and I swear that they are not now where I planted them. Some are but there are others a good couple of metres from the patch I thought I'd planted and in random spots. I think they do spread but maybe there's some squirrel action too? Obviously that wouldn't explain your grid pattern unless you have some very organised squirrels.

They do spread. There is a stunning bank of anemone blanda at magdalen college Oxford

Hmmm vair interesting....I do understand things spreading, but to have them so far from any others I know of is strange (but I'm not complaining!)

I've been a professional gardener for 12 years so I should know about this really, oh well you can't know it all!

Here is a nice picture of the anemones but they are stunning in real life

I planted some 20 corms last autumn, hoping to emulate a 'bank' in a shady place, though the Oxford bank is in sun, but the squirrels dug them up and not one has sprouted

Ah now I read it properly- they are anemone appenina
