The photo below is an experiment. Most of the color in the garden
comes from spring plants. Then, it becomes mostly green. So, to
incorporate plants that bloom during the summer, other than the
usual annuals, and of course daylilies, we did this.
Our crape myrtles reseeded themselves to give us plants, and DH
rooted cuttings from our old yellow privet, so we combined them to
create a border at the back of the garden area. DH is the one with
the green thumb. I'm just the plant plunker decider person.
So, yellow privet hedge with crape myrtles every so feet. We may
have some adjusting to do with how close they are, or it may not
work out at all.
