Does anybody grow any species of Prostanthera?
« on: August 13, 2015, 10:09:42 PM »
I saw an article on "Gardeners' World" entitled "10 unusual herbs to grow" and listed is Prosanthera rotundifolia. http://www.gardenersworld.com/plants/features/herbs/10-unusual-ornamental-herbs-to-grow/5539.html?utm_source=Adestra&utm_medium=email&utm_content=10%20unusual%20ornamental%20herbs&utm_campaign=GW%20weekly%20newsletter%2013%2F08%2F2015 . It looks very nice.

Further research on the internet turned up some other nice plants too - Prostanthera magnifica calling to mind a little the flower of Salvia Pachyphylla which was discussed on this forum recently. It seems that Prosanthera can be grown in pots. Any information would be gratefully received.
I have a small garden in Rome, Italy. Some open soil, some concrete, some paved. Temperatures in winter occasionally down to 0°C. Summer temperatures up to 40°C in the shade. There are never watering restrictions but, of course, there is little natural water for much of June, July and August.
