My Mom and I didn't have very similar tastes on many things. And after having been married with a house of my own for almost 28 years, I don't have the need nor the space for much of what's in Mom's house.
There is a notable exception, however.
My mom did not have a green thumb, by the way. I can't remember anything specific she ever planted in these boxes. But I've always liked them.
When we built our house, we used a lot of concrete. Our floors are stained concrete. Our counter tops in the kitchen and bathrooms are concrete (mixed in a wheel barrow in the front yard and toted inside in 5 gallon buckets to be poured into the mold Mr. H built). When the girls asked what we were going to do for a fireplace surround, their dad said, "Concrete, of course." He meant it as a joke, but we actually did make it from concrete, too!
So the concrete flower boxes are right at home here. All the flowers I planted in them are doing well (so far!) The plantain lily even has a flower bud waiting to bloom. I'm excited to see it. I'll post pictures when it opens.
