I have grown outdoor cucumbers- those with ridged and bumpy skins- with no problems. They taste really cucumbery, much nicer than the insipid supermarket ones. They do need a sunny spot but the tougher skin, that may need to be removed before eating, makes them hardy. You don't need to remove the male flowers from the ridge cucumbers, I generally don't but have had a few bitter ones though this may be because I'd left them a bit too long. I've grown Burpless tasty and Noé.
