Peruvian Lily

ianbrazil(11)November 7, 2012

I realize that Alstroemerias are distinct from lilies but as there is no specific forum I thought I'd take advantage of the common misconception...

I know Alstroemerias are fairly hardy and can certainly be grown in Zones 7 or 8, my question is how "warm hardy" are they? I have heard that if the soil temperature rises above 72F they will not flower. Is there anyone in the far south or Hawaii who grows these successfully?

Thank you for reporting this comment. Undo

They are recommended for hardiness zones as high as 11 or AHS heat zones 8-10 (upto 90-150 days of temps above 86F). In warmer climates, these are considered "cool season" plants and flower best when temps are moderate. Since they are such a popular cut flower to the florist trade, there are a lot of greenhouses that specialize in them and they recommend keeping temperatures no higher than 75F to minimize blind shoots.
