I really quite like this one. It's simple, minimal and the pale pastel shades are very pretty and feminine.
This flower has lost a few of its white petals and has a bug sitting on it. I think it's a cockroach, so this might not be the right one if you're looking for a pretty, decorative image but it's great for a nature theme.
This picture of 3 potted flowers, either camomile or daisies, is available both with a background...
A little animated gif of two flowers, they look like they may be in love or perhaps singing or talking... either way, it's cute if you want an animation.
"He loves me, he loves me not" is what the artist called this pretty image of a daisy with it's petals softly falling to the ground.
This very cheerful singing daisy will put a smile on many faces, I love her pretty dew drop earrings.
If you're looking for a simple, single daisy... this might be the image you're after. It (like most on this page) is available as both an SVG and transparent png.
