This will be my first winter with orchids. I've managed to keep most of them alive -- and many happy, too -- through the summer but I'm a little worried about the winter. I'm trying to figure out which of my dens need a cold winter rest. I keep reading about a nobile type orchid, but I don't know what that means, or how I know if I have one.

I have Dens
parishii,
loddigessii,
little sweet scent,
nestor,
second love,
woo leng,
kingianum,
ise pearl.

If anyone could
tell me which of mine need a cold winter rest I'd appreciate it.

ps. as an aside, my neo. lou sneary just started blooming again less than 3 mos after it finished it's last bloom and smells heavenly, though not strong. I'm still a little amazed I haven't killed all my orchids. Im so obsessed it's hard not to water them every day!
