This crest came to us unnamed, but we can be fairly certain it's a Ferocactus - just don't know which one. If you look closely you can see the spiders have been busy this summer, doing their part in the environment. We don't have any really dangerous spiders here. The Black Widow spider is very rare - with most of my life lived here I've only seen one west of the Cascade mountains. And the Brown Recluse, if it's around at all, is just that: reclusive. Mostly it's the common garden spider. And those are common.
As we take these back into the greenhouses they get sprayed with a good blast of water to get rid of all the webbing and then they'll get some pre-winter systemic insecticide. After that...let's get it over with...Winter, that is!
