My sister sent me a picture of this plant which she said I gave her. I have no idea what it is and would appreciate if someone could identify it.
Leaf shape looks suspiciously like Rose of Sharon, Hibiscus syriacus, but I'd expect to see flower buds (if not full flowers) by this time of year.
Spiraea vanhouttei? (I am seeing the leaves smaller scale than Hibiscus syriacus, but I may be wrong.)
Here is a link that might be useful: S vanhouttei foliage
