Thanks for your kind comments, everyone! But I cannot take all the credit. The truth is, my gardening obsession was destined. My mother has always had an interest in gardening and her current yard/garden is out of control - and it seems I inherited all of her green-thumb genes.
When I bought my place, four years ago, it was pretty much a blank slate - previous owners did little more than plant two rose bushes and grow a "lawn" (primarily weeds). Since it was my first place with dirt (condo living is hard on plant lovers!), I went a little crazy.
Funny thing is, I HATED gardening when I was a kid. Mom always made me do the weeding.

How weird is it that 35 years later, I
enjoy weeding?
Yes, I am a sick twisted soul. It's part of my charm.
