These are my guidelines I use
Crypts no lower than 47
Aechmea no lower than 37. I dont risk any lower on these as I had some turn to mush at 35.. 2 years ago
Neo's no lower than 32 without cover..high 20's I add heat
I also take into consideration if they have a canopy of tree's, shade cloth or greenhouse ..as the temps in these circumsatnces are generally a few degree's warmer without the aid of a heat source.
Low temp here has been 32.7 and I used no heat source. Zero damage not even to the banana tree.
Just my opinion and its what works for me..I have to many to move everytime the weather changes so I move evrything once for winterizing according to what needs what and what heat sources I will use. And there it stays until spring
Now that I wrote this book I will shut up

Hi Mike,

See the link below to google books preview of "Bromeliads for the Contemporary Garden". Scroll down to p171 & 172. Here you will find plants grouped according to their cold sensitivity. It is a great guide when selecting locations for those special plants. BTW, this book, & Andrew Steens new one "Bromeliads the Connoisseur's Guide" are worthy additions to the collectors library. Cheers,

Here is a link that might be useful: Cold sensitivity

pages 156-173 are not part of the review

Thanks HDD, that's exactly what I was looking for. Anyone else have their own personal guidelines?

I can't believe I still haven't picked up either of Andrew Steen's books. Has anyone here in the states come across an easy way to get the Connoisseur's Guide?

Mike,

I always refer to the Cold sensitivity in Bromeliads article at the FCBS web site, so far it is the most accurate and comprehensive information available. It is also well adapted to your conditions being writen by a Florida grower. My long and cold winters are something quite different.

Well it turns out Hoh. brachycephala is not very cold hardy at all. It just took a little while for the damage to show up. Granted some of the blotches on the plant are supposed to be there!

Ouch. that hohenbergia is a beauty, hope it doesn´t get more damage. Protect it please!!!!!. what temp did it?.

If I had to guess I'd have to say somewhere in the low 40s, since it was semi-protected on my patio. It was a little tattered when I bought it and I've been secretly hoping for a pup so I can have one started fresh and clean.

If you decide to leave your broms outside when the temperature drops, make sure they are protected from frost.

I live north of Mike4284m, probably, and I've never seen frost in 16 years. Last week it dropped to 41 on the exposed northern side of my house and 47 on the protected sides and 49 on the south side by the water. I brought in all of my hanging plants and some others that were at hand. I quite liked having all the hanging bromes and orchids in the garage. I wish I could leave a few in there year round.
