Normal aphids do produce adults that fly, which is what the one in the photo is.  Whitefly adults are totally white and look and fly like tiny, tiny butterflies - if you ever see them (hopefully not as they're more of a pest than the run-of-the-mill aphid!) I'm sure you'll recognise them.

It looks like some type of woolly aphid judging by the trunk, but I didn't know they attacked (I assume from the photos) laurel.  There is a laurel aphid in the US that looks a bit like that.

They look like standard aphids to me.  Adult whitefly will be immediately visible as they will fly around the plant when you disturb it.  If you don't see any of those, they are normal aphids.  Repeated spraying with a hand-sprayer containing a few drops of ordinary washing-up liquid in the water should clear them up (it drowns them.)  I use basic 'value' type detergent rather than fancy-smelling ones which may contain things plants don't like.

They've had 12 weeks, so you should have a crop - good luck!

It's a penstemon, Martin.

Yes, you can take cuttings and this is recommended as they aren't all that hardy.  Look under propagation at the RHS penstemon page:

Hi Janet, a lot depends on what the wood was originally treated with.  In general nothing will stick well to anything which has been varnished for example, unless he varnish was sanded off first.  Water-based paints don't work well over oil-based stains either.

Julie, not all varieties flower so you may well have potatoes in your planters regardless of whether you've seen flowers or not.  To maximise your crop, wait until the foliage yellows or dies off - at that point the tubers aren't going to get any larger and you may as well lift them.  When did you plant them?

Ah, I see it's a new bug - I didn't type any.

Lots of thread titles seem to have unnecessary hyphens between the words.  Is this a new quirk on the site or are folk putting them in on purpose for some reason?

Julian, I doubt anyone is going to commit themselves to saying yes, but those look like a fine example of edible Field mushrooms (Agaricus campestris) to me.  All I will say is that I would eat them!  I always do this test first:  I take a small piece of one and place it inside my mouth between bottom lip and teeth for two minutes.  If there is any burning sensation, I don't risk it.
