This had nothing whatever to do with the hostas. You do not say where you

about 15 years or so at best, especially in an unfriendly environment,

hot, sunny lawn.

Interesting. My mother has a clump of birch trees that is 30 years old. I
remember it being planted when I was pregnant with my first child who just
celebrated her 30th birthday.

I doubt these are exceptions. I remember birch that were that old all over
the place.

What sorts die at 15 years?
