Hi Leo, Thanks for the advice with the Ferraria - we're still several months away from 32 °C, so I'll have a look how strong they'll appear then and may shield them in-house to give them some extra time if necessary. trouble with Tigridia Philippiana is: it's not one of the mexican summer growers, it's from chile and summer dormant. The Mexicans I've handled up to now never went dormant in Summer - my list includes chiapiensis, orthantha, pavonia and van-houttei for now - all strictly water driven, even in last years 40°C for weeks horror summer. greetings, Martin Am 03.04.2016 um 20:21 schrieb Leo Martin: > I'm not familiar with that Tigridia, but many species are relatively > high-altitude, cool-growing summer plants.
