This time of year, our entire neighborhood erupts in white. Every lawn has at least two spirea and many have entire hedges of it. I got the impression it was a popular shrub in the 1960’s because although it’s rampant in older neighborhoods, I couldn’t find it in any nursery.
We have a row of them along the south side of our house but we’ve got an empty space right in front of where the sump pump drain exits the house. A friend came to the rescue and offered us some from her lawn—she had been trying to kill them with no luck. (And I can’t think of a better provenance than a plant that refuses to die.) We dug up three small ones and soon, we’ll have a full hedge again.
