Way back when, I spent a couple of summers transplanting, babying, trimming, obsessing and encouraging purple winter creeper euonymus to grow as a ground cover around the front of our house.
I thought it would be the perfect replacement for all the mulch that Shelley kept tracking in the house. Plus, each spring and fall we were either breaking our backs spreading mulch or paying a small fortune to have it spread.
Hindsight is 20/20. I should have just yanked some kudzu up off the side of the road and slung it down - I think I can hear this stuff growing as I type and it's threatening to come into the house.
Nelson loves it though - he burrows in it and watches the world go by.
