Funny you should ask that Susan. All the other homes in our cul de sac are professionally landscaped with lots of beautiful bushes and trees, all very neatly tucked in with black mulch. I always admire how neat they look even when things are winding down. As it turns out, I have a friends and family get together day at my house and the first year that our neighbors (all have jobs and are younger than us) were invited, they told us how wonderful it was for them to turn the corner into our street (we're on the corner) and see all the ever changing beautiful colors coming from our gardens.
We have a very loose plan, now and then, as to what to put in the gardens and even that keeps changing. My object is to fill every available spot with something. I'm running out of room.
