Many of the Austins that are recommended as small climbers would probably work. I'm trying that with Othello, Tess, Brother Cadfael and Leander. Cori Ann is using pillars for something similar and has added Cl Iceberg. She researched this extensively so hopefully she'll pipe in. Malorena also has some beauties pillared. I just bought the roses first because they were cheap and then had to figure out where they'd fit. I have a lot of walls so hopefully it will look OK : )

I have tall posts in the ground that I want to pillar with roses. Have another Leander coming from Austin roses this year. Can get some of the Kordes roses from Chamblees [am 2 hours from them] I think they have Cl. Iceberg too. Would love to see some photos if anyone has some - thanks for the suggestions!

Spirit of Freedom, Nahema, The Wedgewood Rose or Colette are all great roses for a pillar. Eden is a good pillar rose too but takes time to get going.

I just ordered Florentian and Jasmina climbers too from Kordes and have Elegant Fairy Tale that isnt supposed to be a climber but has made an excellent pillar rose for me.

Abe Darby would be a good one too I bet and Pat Austin would as well

This is my climbing Iceberg on an 8' post. It was badly neglected for years (never fertilized or properly pruned as a climber, but I just started to pay attention to it in the last year or so). Sorry for the poor quality image.

Heritage is taller in a warm climate and has few thorns.

Well... I just started my first obelisks in the fall and have never actually done a pillar, so I can't give personal experience. But this site is really helpful: http://scvrs.homestead.com/rosesthatclimb.html

It specifically mentions noisettes. The full list of roses the article says do well with pillars are:

....and here's a fun post about obelisks with lots of enabling photos. :) http://forums.gardenweb.com/discussions/4205651/tower-of-roses-obelisks?n=42

What a great link and list, Cori Ann. I might take exception with New Daw, however. I have five (5) and don't consider it a short climber, but with it's limber YOUNG growth I can see how it could make an excellent pillar.

Yeah I would take out anything that is listed as really thorny too. Life is too short! Although I let Jeri and Jackie convince me to put Sombriel on a huge arch. That's going to be a beast. I'm a little scared.

Go for thornless or close to it like Kim said (in another post I think... but he said it somewhere). Make your life more enjoyable. We don't need to be masochistic with sadistic roses. :)

How true! I have a potted Sombreuil.....think I will just plant it where it can drape over a fence. I thought of Crepuscule - few thorns, pliable. I have 2 young ones that will be climbing an arbor. Going to research all the wonderful suggestions - few thorns sounds like a very good suggestion!
