Great...for the 3 weeks its blooming...then, a horrible tangled vine that tangles up everywhere, and wants to be watered every 10 minutes, unless its raining, then every 15...

What do you mean exactly?

Wisteria are a huge hassle for 10 months of the year, are a particular pain in the butt in early to late summer as they try to engulf everything around them with shoots and vines.

They require a program of extremely hard pruning twice a year, timed to suppress green growth and increase flower buds. They are initially only attractive in late May or early June (depending on where you are) IF they flower. Once they start pushing green shoots, they quickly become annoying. It's worth it, of course, for the purple or white flowers. Additionally, it's best to start with an older collected specimen or an airlayer from an older plant, as it can take a decade or so for seedlings to become mature enough to produce flower buds.

I collected a fairly large wisteria from NYC a couple of years ago that I'm working on.  I guess it depends on what you think is a pain with them.  They do put out growth fairly quickly - growth can extend a few inches in less than 24 hours.  That being said, with wisteria,  it's fairly easy to just cut it back every week or so since you're not necessarily doing precise branch work as you would with most deciduous material.

For me, the biggest pain is that it continually sends up new runners out of the pot that I'm constantly removing.  I'll dig back some of the soil and cut them down low, and the next weekend have to do it again.  That bothers me more than anything.

They are thirsty tree, so I have mine in a fairly heavy organic mix.  All my other trees, with the exception of my bald cypress, are in 100% inorganic mix, and I wouldn't be able to keep up with watering my wisteria in that mix.

Otherwise, they are fairly resistant to pests and diseases, love full sun, and are fairly maintenance free in my opinion.

ha ha!

They can be great, although they can be a pain too.  But the flowers make it all worth it.  Here are 2 pics, one from the snowstorm we had a few weeks ago, and one in it's old home in washington.  It's the only tree not in my cold house as it's just too big.  It'll be going into a real bonsai pot again this year.

Nice one beng.

I'm growing one on Bill's varieties, Dwarf Wisteria.  Yes, it take a lot of water, but is very forgiving too.  And if something dies, just cut off and regrow lol  And I actually like it without flowers a lot too.  It's got pretty, tender shaped leaves, and it's so full and a lovely green color.  I think I'm in the minority here though  ,
