This one has totally surprised me! I have 3 small seedlings, 1 planted and 2 in pots, which took 3 weeks of sub zero temps with at least 2 excursions to -4c/24.8v and 2 lower dips to -5c/23f.

The 2 in pots have about 25% leaf burn, the planted one is still pristine with no damage what so ever. All 3 were understory to my Acacia. I have since brought the 2 in pots indoors to help recovery. They are still alive and growing again slowly.

Regards Andy,

Bangor, Norin Iron Zone 9a Min temp normally around -3 Degrees C, rarely -6C. Only 2 x -2.0C so far, verging on 9b this year. No snow or Frost this Winter. Several just subzero's this year, lets hope it stays this way. Normally around 5C to 10C + in winter, with lots of wind & rain. Summers usually better, 20C to 25 C occasionally 25C to 28C, also quite humid being a coastal town

My died after 21°F (-6°C). This plant survived around 10 years under a evergreen canopy.

This plant seems to need very little warmth to grow vigorously. It's a monster at the chilly San Francisco Botanical Garden.
