Great looking plants!
I second both of Jmmy's questions.
In addition, what kinds of conditions are your Helis experiancing, BigBella? (Humidity, temps, etc)
In terms of growing conditions, the plants all experience fairly high humidity -- in the 70 percentile range and higher (though have fallen into the 40-50% range on rare occasions) -- and Tbs that rarely exceed 25˚-30˚C for any real length of time. More importantly and, again, analogous to growing highland
Nepenthes or
Darlingtonia,
Heliamphora require a consistent fall in Tb at night. Since I live on the Northern California coast, it is almost always fairly cool at dusk, in the 12˚ C range -- probably colder tonight. I also grow the bulk of the plants in shallow water trays, since I cannot ensure that they are frequently watered otherwise. Some growers, however, swear against that practice -- but it works for me.
As far as the other question about partially raising
Heliamphora as a lowlander, frequent watering would be required and conditions that would allow for reasonably high humidity -- misting, etc. One solution to this would be to grow any number of hybrid forms which allow for far greater latitude in terms of cultivation. A friend of mine in Austin, Texas, grows a few plants (
H. nutans x heterodoxa, H. heterodoxa x minor, H. heterodoxa x ionasii, etc) which seem to thrive and flower, even in their sweltering summers. One encouraging thing I could offer, is that UC Berkeley's Botanical Gardens have some nice
Heliamphora in their collection; and when last I visited, they were in a full, poorly-vented enclosure, and the Tb was well in excess of 30˚C.
In terms of the
Heliamphora sp. "Angasima," and the others, I haven't had the plants long enough to offer any real advice or opinion. I spoke with a couple of growers in the UK who suggested that some of the "new" species were fairly vigorous but others disagreed; aside from that, it's anyone's guess . . .
