Title: Petunia patagonica advice required
Post by: Neil on September 07, 2019, 11:46:27 AM: Just seen some photos of Petunia patagonica, trying to find information about its' suitable for growing outside in the climate we have in the South of England?

I believe it is quite hard to get it to flower freely in cultivation, but it can be done - some lovely plants appear on the show benches in the UK.

Read how it is treated in Canada ... https://botanyphoto.botanicalgarden.ubc.ca/2009/05/petunia-patagonica/ (https://botanyphoto.botanicalgarden.ubc.ca/2009/05/petunia-patagonica/)

Plenty fresh air seems key, for a start!

Post by: Neil on September 07, 2019, 07:06:46 PM: Thank you Maggi, I only have 300 meters and I to would be in the channel, and there is always a wind blowing living up the top of the cliffs. There is a photo of one flowering at RHS Harlow Carr https://commons.wikimedia.org/wiki/File:Petunia_patagonica_-_RHS_Garden_Harlow_Carr_-_North_Yorkshire,_England_-_DSC01459.jpg which I assume is outside. However, as my climate is very similar to that of Vancouver I think I will give it a go

Post by: Leucogenes on September 07, 2019, 07:26:55 PM: Also I thank you for the helpful information... Maggi.
It's always amazing how quickly and reliably you have a clue to almost all questions.

Neil... good luck.

Post by: Maggi Young on September 07, 2019, 07:49:21 PM: Hmm, not sure about that plant at Harlow Carr being outside, Neil - much more likely to be in the alpine house. Good luck with your trial out of doors - if it flowers like mad you'll make all the folk growing it under glass for shows really jealous!!

Post by: Neil on September 26, 2019, 11:00:33 AM: Thank you David, I have just seen your post :-[ I had seen that one it confirms that it should survive outside on the South of Coast of England as we have a similar climate to Vancouver.

Post by: Neil on November 02, 2019, 03:47:45 PM: Now that I have a plant ;D I am going to try and propagate it by taking some cuttings but what is it best media to root the cuttings in?
