If you are, you should totally follow Leaf Magazine. They focus more on home and garden stuff, and would be a great resource for new products at high-end homes and design ideas.

They also have this photo of the Duke of Windsor working in his gardens in wing tips. So there’s that.

The magazine’s founders, landscape designers Rochelle Greayer and Susan Cohen, are on the vowel-challenged blogging platform as well.
