They sell seeds. That is good. Are you in Australia? I probably will order some. However, what if I am only interested in potted plants? I think there is a business model problem. Some experts may conclude that these are unfit for the US because of their Hardiness 11 zones. However, most peopleÂs house environments are Hardiness 11+. These can be cheaply produced in Central and South Americas and shipped to us. Wal-Mart, etc. are very successful. Partially because they follow up on what items are sold and how many are sold. If an item is not popular for a year, then they stop carrying it. This model does not work for live plants, birds, fish and other agriculture products. People already have it and keeping it. There is no need for them to buy another one. However there are many new hobbyists show up every year. The correct method should be re-carry it every 2-3 years to probe the market.

I agree, an Epi hybrid, possibly multigeneric, including Disocactus (Nopalxochia) kimnachii in its pedigree as well as Epiphyllum. There are a number of xEpicactus hybrids with that flower form and color pattern, but the one from my books that comes closest is xEpicactus 'Marseillaise', on page 94 of of Innes & Glass's The Illustrated Encyclopedia of Cacti. But this is a guess. If you can find a copy of this book, in the library, you may find one that is closer. Happy Growing! John in St Petersburg

That is a great example of microclimates JoJo! The time spent at the minimum temperature (minutes, hours, days) plays a big role in what temperatures a plant can survive. So does the amount of water in the plant, and in the soil. Dry plants are much more tolerant of cold compared to wet plants. Plants in the ground can survive colder temperatures than plants in pots. I have found most of my plants can tolerate much lower temperatures than typically listed. These lows are brief, just a few hours at most, and it's at least 20 degrees warmer during the day. So plants that are supposed to not go below the mid-thirties F can tolerate minimum temperatures in the high twenties. Agave ferdinand-regis is listed at both +5, and -12 in the list above. The difference between a minimum average temperature, absolute minimum temperature, and Fahrenheit and Celsius scales is often confused. Minimum temperature listings should be regarded with great suspicion, even when coming from a more or less credible source like Desert-Tropicals. It is better to research the plants natural environmental conditions. I would not give much credence to this, or any other so called 'minimum temperature' list. There are too many variables for these to be accurate to any degree. ;) Brad

I think your plant just needs a lot more light. If you have it indoors, glass actually cuts down the intensity of the light quite a bit. Epi hybrids will burn in full sun, so it doesn't surprise me that the one you left outdoors burned. I would make sure that if you have the plant indoors, that it's close enough to the glass to be hit directly by the sunlight coming through the window. I have epis in south-facing windows where they get hit with a lot of light, and they do quite well, only burning if they are not adequately hydrated. If I put them in full sun, I imagine they would burn.
