There are some interesting garden sites listed in this month's
Garden Design magazine. Technically I guess they're 'blogs'
You might look at these:

gardenrant.com

seedhead.com (I enjoyed the Nurseries to Know section)

something to do when you're not gardening - or waiting for
Spring.

Garden Design also had an interesting article this month
on 100 new plants.......some tempting beauties there!
