I love to grow Rosemary here in NW Oregon. It has proven hearty although the tips will die back after a freeze.
I have propagated some starts and shared with friends as well as planted other plants around the property just in case a hard freeze takes my mother plant.
It has proven a little troublesome keeping it pruned enough so as not to get too Woody and gangly.
It has been interesting to watch the honey bees not only collect nectar and pollen but also mine something around the base of the Rosemary plant. They have worked dilegently only around the rosemary, I haven't seen them on the ground anywhere else. Fascinating.
