We grow them in dry locations with plenty of sun.

Here is a humilis (I think) growing on rocks in a lot of sun at the American Orchid Society.

Yeah, that looks like a humilis. By chance do you know if it is growing in a rock crevice? I can't really tell from the picture. I am just wondering if there is little to no soil attached to the plant pictured?
Thanks for the follow-ups bromadams.

I think those are some pretty big rocks with no dirt in sight.

I did have Bromelia Humilis until it got down to 26f last week.

Turtlewalker,
Where do you live? Are yours plants directly in the ground? Are all of your terrestrials left out to the elements or do you protect some of them? I am wondering if I should put mine in a pot of bark so there is not as much water retention in the pot.

I live in Bradenton, Fl. we get a bad freeze about every 5 years and only gets down to 32f 2 or 3 times in the winter which the plants can take. My Bromelia Humilis has been growing in the ground for about 6 years or so. Alot my plants are left out to the elements and are not covered. I have way to many to cover up. I do cover some of the plants that are in pots that are not planted in the ground like dyckia, Deuterocohnia, Orthophytum, Hechtia and few others I have in pots. They all did well with no damage. I did put 2 Dyckia estevesii in my shed and one did get a little damage from the cold.

Hi turtlewalker,

I have a lot of young Ursulaea macvaughii seedlings growing up and I am thirsty for knowledge about their culture as I've never grown them before. I had a bad experience with an adult plant I got through the post and which suffered serious cold damage, and I am interested to find out just how tough they are and understand more of what they will tolerate in regards to hot and cold extremes.

Could you please tell me if your Ursulaea macvaughii was exposed to these same conditions as the plants mentioned above without any cover and if so what is the lowest temperature you have found it to tolerate without damage?

Also what is your experience with this plant in regards to heat tolerance?

Thanks in advance, all the best, Nev.

Not all Ursulaea macvaughii are the same. I had one that was a bear to keep alive.
This plant was not that far away from the others and not covered.
For the most part it get full sun for about 5 hours and the only water is when is rains, I do water some times at the end of winter when it hot with no rain. My part of Florida can get in the 90's every day in the summer, April - Oct .
