Need robust icon set for designs (top down)

I'm looking for a robust, top down plant & tree (even buildings and such are fine) clipart set.

Free is always nice, but if I'm paying I'd like a complete set with easily recognizable icons for common plants and trees.

Searching has turned some up but they have to be purchased as small sheets, and don't necessarily match or have the typical plants. Before I plunk money down I was wondering if anyone had a favorite all encompassing set they can point me to.

Thanks

Hi Victor;
My wife uses clipart in her projects.
She suggested you look on Etsy.com  or creativemarket.com
They are both her go spots when she needs something.

Thanks Thomas,

Yes I keep looking for good clipart. Adobe has some good stuff but you have to subscribe for $30 a month!
