First spring flowers!

We're finally seeing some flowers around here! Lesser celandine (Чистяк весенний) was the first to start blooming.  I loved the literary references in the Wikipedia article.  C. S. Lewis mentioned this plant, and Wordworth loved it.  Here's part of a poem that he wrote about it:

There's a flower that shall be mine,
'Tis the little Celandine. . . .

Ere a leaf is on a bush,
In the time before the Thrush
Has a thought about its nest,
Thou wild come with half a call,
Spreading out thy glossy breast
Like a careless Prodigal;
Telling tales about the sun,
When we've little warmth, or none.

. . . Spring is coming, Thou art come!

Here the lesser celandine actually started blooming a few weeks ago, at least in the places where there are hot water pipes under the ground.  I really wanted to get closer to take some photos and look at it, but the babushki are so protective of that area.  Some of the celandine has taken off by itself outside the flower bed, and I was thinking of trying to sneak one of those wild plants away.  Then Will solved my problem by buying me a beautiful bunch of it at the market.

So, today we studied the plant that we have.  We looked at its roots. . .

trimmed off the old blooms and potted it,

did some research in our books,

and, of course, drew it:

We've also seen a few more flowers!  Soon there will be too many to keep track of, but so far, it's easy.  The first was this celandine.  Then yesterday we found violets and a tiny, yellow, start-shaped wildflower.  I was so excited!  I especially love violets.  And today we saw the first few dandelion blooms.  Can anyone help us with identifying the yellow star flowers below?  That's a little bulb root, if you can't see it well.
