There is a large vine on the fence by the lake that was not there last year. Its roots are buried under a concrete fencepost and it survived the coldest winter in recent history with no care at all. I assumed it was an annoying weed I would have to pull out,  probably two hours’ work. But overnight it opened its blossoms. It is Crossvine (Bignonia Capreolata to the naturalists).  A beautiful reminder that Nature has wonderful surprises in store for us in places we least expect to find them.
