Funny how we coddle some plants and they struggle and others, well, they seem to have a survival gene built into them. I have one rose half hidden under a large pineapple guava shrub, discovered it after we moved in when it sent out a lovely coral pink bloom the first spring. Forgot about it until the next spring and again this spring, each time when it sends out a single bloom. It does not get any water other than what it got during a rain shower, nothing, all summer long and it's not gopher caged either, yet, there it is.
Guess it deserves digging up and planting in a more appropriate spot where it will get regular water. Bet it will just reward me with more than one bloom at a time, unless it won't like being coddled.
