Doc, I have two Masdies that I have had for two years. They grow well, but no blooms. I was told they were warm tolerant, but still no blooms.
One is White Angel and the other is Falcata 'Sunset' x FalconSunrise 'Scarlet' and I have no idea what they look like anymore. Like Ross said, get warm tolerant and try your luck. You will never know until you try. I am too stubborn to let these two go, but I should sell them and let others have a go at blooming them.
