Frozen dendrobium - any hope?

[S_Mazza]

Hello all,

I did something foolish. I have (or had) one dendrobium - Den. Anosmum "Little Sweet Scent" (which for some reason I thought was a nobile type until now). The temperatures in my area have been nice during the day, so I have taken a few plants outside to enjoy the sun. Well, I foolishly forgot to bring the dendrobium back in before nightfall, and it spent the night below freezing temperatures. Maybe around 25F at the lowest.

Before "the incident", it had a few old canes 1"-8" tall, one nice tall cane of about 12" and one fast-growing soft green cane of about 2". Now, the soft new cane is definitely dead. The tall cane is dropping the leaves, and has lost some of its rigidity.

The point of this post is, has anyone seen a dendrobium nobile grow a new cane from the roots after damage like this? Or is it like damaging a monopodial orchid - hurt the growth point, and it's over?
