Manfreda and Polianthes

Jon's a very sharp guy with wide horticultural interests who is also doing some
breeding work in other areas, and I expect we'll see a lot of interesting
plants coming out of his programs.

Last winter, and actually at least the last 5 winters here, have not been 
nearly as harsh, as far as just how cold it got, as what we saw in the previous 
20-odd years (the limit of my experience in the area). We used to routinely see 
winter lows in the -18 to -23 C range (0 to -10 F), with odd -28 C (-20 F) 
spikes. The last few years we've seen nothing below 0 F, and not much below 10 
F (-12 C). At least one USDA zone warmer, in terms of what's surviving 
outdoors without protection, than "normal", whatever that means.

There is a guy locally who grows tuberoses for cut flower sales at the farmer's
market, but as of 2-3 years ago, he was not leaving them in the ground over
winter. (As an aside, he was using a machine normally used somehow by the local
grape growers to dig the tubers each fall.) Something else to ask next spring. 
I've never tried any polianthes outdoors here, just assuming they wouldn't make 
it, but maybe I should rethink that.
