Actually there is a real decidua 'Pendula'. It was in cultivation in Europe many years ago, but probably never got into cultivation here in the U.S. Here, you have kaempferi 'Pendula', kaempferi 'Julian's Weeper', laricina 'Nash's Pendula' (invalid cultivar name) possibly a 4th one that is likely x marschlinsii that is sold as decidua 'Pendula'. There is also 'Stiff Weeping' that is in the trade here and also 'Blue Rabbit Weeping' in Europe. Not to mention the strongly weeping hybrid taxon L. x pendula (which is decidua x laricina).

Mine are within sight of each other so I just went out to eyeball them. Both are about 4 years old. Niagara Falls veins are more prominent, has more ripples, and cups downward while Green Piecrust so far cups up, and for whatever reason is more resistant to leaf damage. GP will get to be slightly larger according to Hosta Handbook.

Thanks for the responses, Jasmar, Cascade and PoolGuyNJ. I completely agree with you about the benefits to local service and support of the local economy. I think the problem is the two pool companies I have had contact with may just be terrible. First company was the one the realtor got to come inspect pool before closing. They also gave us a heart-attack inducing ($45K) estimate to completely refurbish the pool to like new condition. When I contacted them back with questions about the estimates, never could get a response. Unfortunately, we had to call in on our home/pool warranty Friday (when the pool was opened, one skimmer and one pump will not start), and guess who the warranty assigned to work on the pool?! Inspection company! Blech. So, since we were not impressed with them after we bought the house, we solicited suggestions from friends who were pool owners and got company #2. Had them come, look at the equipment/setup to give us a reno estimate, and hired them for opening and closing. It's been four months and have not gotten the full reno estimate (got a verbal ballpark of $25K at walkthru), but got those prices for the necessaries above after two more followups. The opening and closing process has been a PITA, as the company seems very poor at communication. First came to close without an appt and did not use all the chemicals left by the seller which we asked for them to use up first and wanted to charge an extra $250 for chems I had sitting in my garage! They did waive the chem charges since it was their miscommunication, which was nice and stand-up of them. Second, when they came back to open, took three weeks to get an appt, they changed their policies from working on Saturdays, so we had to take a work day off to meet them, then the nice man they sent did not speak English and couldn't communicate what needs to be done with the pool. He could only say things did not work, but that was it. He indicated missing plug/part in the skimmer, but I don't know how that could be since his company closed it and put all parts in the bag which sat in the deck box since January. Also, starting up the hot tub only one of the pumps would work and it causes water to come up through the holes in the deck and spew all over the concrete. These little plumbed holes seem like they should be for air to go down into the spa to aerate the water, but we are having water back out of them. Again, he had no idea but could only shrug and say 'not work.' They also charge $75/hr for vacuuming but we thought it was such a swamp lets have the pros tackle it first then we can maintain it throughout the season. They sent a kid with a Leaf Eater who only started 4 days ago. I thought I was inexperienced with only four months with a pool but even I beat four days!! He worked on it with Leaf Eater for about an hour and a half then packed up and left. He brought a vacuum hose but didn't use it. We still have a ton of leaves and silt in the pool. Now what? How was that getting it cleaned to be opened up? No followup instructions were given. They also want to sell me those parts I mentioned in the first post but gave me no recs on installers/electricians - I'm on my own after they sell me the parts. That's not a great endorsement for 'buy local because they are more helpful and supportive.' When I called the day after the opening and said I wasn't sure what the opener was trying to tell me to do the next day, maybe five bags shock? or maybe he was coming back to do 5 bags shock?, they said they couldn't get him on the phone and said 'is it cloudy? yeah, probably five bags shock.' I have to think there is more to it than over-the-phone diagnosis. So our $500 package for opening and closing was less than satisfactory. This co charges $220/mo plus chemicals for weekly service in OKC. That was too rich for our blood, maybe there are other services that are more in line with what you say Jasmar. Will keep looking. (FYI, we were not thinking to fill in the pool, but maybe the separate hot tub. It was Pool Co #2 who suggested filling it with dirt and making a planter, so if there are regulations about it, they were not too concerned with them.) I know there are good local pool co's out there but I am having a difficult time finding them, even using friend's/realtor's referrals. Just so disheartened! I ended up taking a water sample to Leslie's yesterday and was pleasantly surprised by their knowledgeable and helpful staff. They offered to show me how to use the test kit, explained what all the chem levels mean, and even helped talk me through backwashing and how to run the filter. They said the tests show no chlorine in the pool, so all the organic debris is eating it up faster than I can add it, so keep cleaning the pool and add more shock and some other stuff (floc/enhancer I think) in about four hours. Told me to keep a list of all the chems that seller left for us, and every time my H20 is tested they can help me find out what I need to buy and what I already have. so far best experience with a pool co! (and I know there are not a lot of leslie's fans here, but that has just been my experience). When the pool co #1 comes next week to fix warranty problems, I will see if I can find out about plumbing for cleaners. I was back there looking at the sand filter pressure and noticed a big thing that said 'Polaris' with an on/off switch plumbed in on one of the PVC lines. Will take a photo and post if they cannot tell me what's what. Here is a link that might be useful: Miracle of Chlorine!

Simplicity does make for less technical issues down the road, but I don't want to trade my iPhone for my old flip phone either. I feel your pain, but this would have happened (i.e. moisture in the panes) with a poorly sealed clear glass unit at some point if the seal is the issue. The Low-e has failed here and in a vast majority of the cases, it is because of the introduction of moisture (i.e. humidity) into the sealed unit. There should be a warranty sticker with a serial number on the window that should provide them all the information that they need. Changing out the fixed units is a PITB but swapping out the operable units is pretty easy. If they provide you with replacement units, that is really all you can ask of a manufacturer. I can't condemn them for that. Now...if they are turning out a bunch of crap product and it is failing left, right, and center...that is a poor example of quality and execution. That said, we have had bad batches of glass from even the best of suppliers. Keep us posted and hopefully they don't the process too ponderous. It shouldn't have to be that hard and you are 100% right about that.
