I found this plant between my vegetables when it was small and thought it looked interesting, so it placed it somewhere else. I couldn't imagine then that it would grow to be a sphere of almost a meter across within a couple of months.
Anyway, I'm curious what it is. Like I said, it's about 1 meter, roughly spherical. It is an blueish/grayish green, and has a lot of fine leaves of about 8 to 10 cm. I'm not sure what the right English word is to describe the shape of the leaves, but they look like a drawing of a Christmas tree.
Recently it developed small stalks or "tails" each with many flower buds, which look like they may become yellow flowers. Any fragments of red on the picture are from a different flower.
This picture was taken in my garden in The Netherlands, North-Western Europe.
