Recommendations for places with pretty sights?

Preferably free. I just need to get out of the house more often, see and touch some grass for my mental health. I just want to be in a place that has a nice scenery of the plant variety. Parks with lots of flowers and shrubs. Emphasis on flowers and shrubs cus some of these parks are 95% grass and trees. Just to sit and stare and zone out. Think about things. Walk around a little.

If the sight is the building itself and the items in it, I’d like it to be colorful and not just bland concrete and brick. Not just black, white, grey, and colors of wood.
