Try and cancel the order. Try really, really hard.

It isn't just that it is late to try and establish small roses before winter, but I've tried to grow Sharifa Asma own root (and a fair number of other Austins), and don't go there. They actually do things like grow and bloom as budded plants, something they aren't keen to do as own-roots. If Palatine carries them, that would be my first choice. Otherwise David Austin in Texas has budded plants.

See if they'll give you a spring shipment date. Most places will do that. If not your best bet is to dig a trench and bury them completely for the winter. Be sure to mark the spot very well so you can find them and dig them out without damaging them next spring.

Thanks for your responses. I managed to get the ship date moved to April. In the meantime, now that I have bought myself some time, I'll do some more research on my choices. I'll definitely give more thought to own-root vs. grafted. When I placed the order I thought own-root was what I was supposed to get and specifically looked for it.
