hello Ivo - as we say in the u.k. "don't give up your day job" - but I love your sense of humour. I was going down a similar road to Sue - although as we all know, jardinnaires are almost always made in ceramics of one sort or another, and this is a little on the small side for one of those. Yours in more is reminicent of a flower/posy vase. I was thinking of the colourful Czech ones which have ground and bevelled top edges, with a metal grill/grid fitting over the top. Is there any wear on the shoulder where a metal top might have rubbed, and what if any is the extent of wear on the base? Is there water staining on the inside?? Might we call the colour 'Bristol Blue' or 'poison bottle blue. As you can see, I don't really know, but this might encourage other people to help you.
