Re: Dutchman's Pipe

Nan-

I'm not sure which Dutchman's Pipe you have - I, for now, will assume that it 
is either elegans/repens/littoralis (in my book all three names refer to one) 
or gigantea.  I've had mine for 2 summers now and still have mine in a pot 
because I feared hardiness.  This is the first summer mine has bloomed.  The 
blooms appears to come in cycles - a group of blooms at one time then 
none....so far this summer I've had three cycles (this last time about 7 
blooms at one time :o)).  The vine might bloom more continuously if it was in 
a sunnier spot.  Mine is in a "filtered sun" location for the entire day.

I've noticed that mine has gotten a woodier stem with age and the vine does 
have a few tendrils....I've simply helped in twine around my trellis.  The 
vine is probably a good 10 feet at this point.  I did cut it back last year 
to overwinter it in the greenhouse.  I have a small greenhouse and I needed 
the room.

I did do a little reading last night, via the net, and a San Marcos, Texas 
grower says that the foliage hardy to 25 degrees and root hardy to 20 
degrees.  (I believe that San Marcos is in zone 7-8)

I took a cutting from gigantea a couple of weeks ago and the foliage has gone 
but the stem is still alive and beginning to put on small leaves.  If this 
cutting is successful I am going to try to overwinter the mother plant in the 
ground this winter.

Nan, I hope this helps....if I find additional information I will let you 
know.  I sent you the page (by attachment) that I got the information from 
privately to you.

Happy gardening
