I think as others have said, the first block gives the definite feel of a formal garden. Thus, I think any of the names suggested such as English Garden, French Garden, etc. would fit. I think you could easily call it Rhonda's Garden.
I agree that it's both too complex and pretty for a sports themed name. I do think you could do a similar, but simpler, block to go for a sports theme. Perhaps, removing the corner details and adding something else in place.
The second block, my favorite, definitely brings to mind a lovely formal fountain garden such as one might see in a rich desert sheikh's palace. So, I do like the name Moroccan Fountain or Oasis Garden.
Your blocks are beautiful and complicated. You provide challenge to all board members who want to improve their skills!!
