You can find your nearest extension office here. In a recent thread requesting two lawngrass identifications, I compared the ligule, auricles, grains of the blades, etc. as best I could and determined one was Kentucky Bluegrass and the other was rough bluegrass. Another person thought the lawn might be annual ryegrass. We were both wrong. The gentleman took samples to his cooperative extension service, which identified them as tall fescue. Didn't look anything like tall fescue to me, but they are much more likely to be right than my guesswork. You can take the pictures and show us, but we can't guarantee positive identification. Sorry about thinking it was powdery mildew. It looks just like that, and I never saw water droplets look like that. Maybe it was the flash in daylight.

Your Clematis "Crystal Fountain" is a pruning group 2...but in saying that it is in your plants best interest to hard prune her the first season in your garden to promote the growing of the root system so you'll have a healthy,strong and vigorous clematis..."Wilt" is not neccessarily the death of a clematis...there are two schools of thought on the subject ..one being it's a fungus and the other is that it is caused by an immature rootsystem NOT being able to handle the top growth of the vine..Hence hard pruning is recommended the first year to allow your plant to focus on growing a stronger root system and not all the vines...When Clematis do "wilt" you simple prune that vine even with the soil and give her a liquid feed...she should shoot up new vines..some are known to skip a season and re-emerge the next with such vigor...the biggest mistake most people make is that they assume it has died and stop watering..that WILL kill your clematis..You must STILL keep that area moist for the root to keep growing and start producing vines again...You do realize that your Clematis "Crystal Fountain" will not grow too tall?..Mine is about 4 feet tall right now..and I have mine in morning sun and filtered light in the afternoon..Lowe's has some 5 foot obelisks that would be great for letting her grow on..it's whatever your personal taste is...have you planted it yet?...If not..when you do..Plant her 2-4 inches deeper than the pot she is in with a handful of bonemeal in the hole...and keep her moist..NOT SOGGY WET ..but moist during her transition period in her new home...she will get more beautiful with each passing year...What size pot was she in?...Jeanne

Cutting them back only delays flowering. It doesn't stop it or harm the plants. In fact, cutting them back makes them fuller and invigorates them. Better to cut them back than not. If you've got brown growth with new shoots cut all the brown growth back to the lowest buds even though they are dormant. It will sprount out more vines. All Clematis, no matter what variety they are should be hard pruned the first few years.

It is hard to tell what variety it is - there are many hundreds of named varieties and many 'unknowns' that are great tasting and have been propagated widely as well. Many leaves look similar, many fruits look similar. The important question is "how does it taste?" If it tastes great to you, assuming you have let them get completely ripe, then enjoy them, propagate the cuttings and share with friends, etc The best way to identify it is to find out from whoever planted it, otherwise it is just an educated guess.
