Mine are also the tallest I've seen. If I measure it I'll get back to you

I'm beginning to wonder about the expert advice usually given, which is to
grow these things in rich soil. The best specimens round here are always
coming out of cracks in paths etc.
I noticed some good specimens in Greece this year which were growing out
concrete on the edge of a mountain road with no obvious source of nutrients
or moisture.
