Low temp capability confirmed... I had half a dozen or so that breezed thru temperatures that froze the water in my irrigation system and burst my plumbing seals! I have 2 left I recently potted up into 5 gallon buckets. They are happy to stretch out their roots. I'm hoping for a speed up in growth by the end of the summer. I think this is one of those plants that turns into a relative rocketship once it trunks.
Zeeth,
Save yourself several years and go to a nursery that will let you select the ones with the best color in at least a 3 gal. They have become VERY inexpensive, at least that's the case up here in N. Florida.
I didn't know you got Syzygiums in India. By the way, that Travellers palm is quite close to your wall. They can get a big but on them once they trunk.
There is also a red version just released from Madagascar called Ravenala sp Honkandambo.
Best regards
Tyrone
