Zone Denial for Cortaderia 'Pumila'......

gardenlady48(z5 IL)March 19, 2006

Is there anyone out there growing this grass in zone 5? We live in central Illinois. There is a woman that grows it in a protected corner of her house. I just have to have this one and wondering who has success in zone 5???

We have one known clump that has survived in our county. It is located in town, close to the warm South wall of a busy pizza restaurant out of harsh winds. It only grows 3' to 4' including plumes. Note though that we have had unusually warm winters recently. Also, out in the country, I can not keep it alive. Even a local nursery who offered it for retail out of their fields has discontinued sales. Unless you are willing to provide special unnatural conditions, you are up for a challenge. Remember to verify that you get Pumilla and not some of the more temperature sensitive Cortaderia.

It's not Pumila but it's zone denial for Cortaderia. :) I bought pink pampas seeds on ebay in 2004. Over-wintered it in a shed it's first winter and left it in the ground it's second. Uncovered it March 27th and since then I've found a new shoot (that must have been coming up when it was covered-- it was about 3inches high and almost white when I found it) and two of the old cut ones are greening. Our lowest temp last winter was -5 but there were also nights of -4 and -1. I hope it'll be strong enough to plume this year and isn't just barely holding on. ---If it plumes it'll be for the first time. I'm crossing my fingers!!! :)
