I have had this for years. In Northern Ca. I have been growing it in the greenhouse and on a covered patio. A few months ago I put some in the ground and mulched then with fine fir bark. They are doing fine. The temperature dropped to 28º in mid January and there was not the slightest hint of leaf damage. One is sending up a flower spike. The only problem I have had with it is with snails and slugs. I was told they are epiphytic, but they probably need some detritus to root in. I may give it a try when my redwoods get a little bigger. A friend grew some in her greenhouse that were huge, a very nice strain.

I have had this plant before, many years ago and lost it, so I finally got it back again and it is everything, if not more, than the description. It bloomed 4 flowers, the first two were crossed with a white amaryllis and the last two were self-pollenated. I stuck a couple of Jobe's plant spikes in the pot and it bloomed. It is greenhouse-grown with a minimum temp of 55 degrees in winter.

I was discouraged by what I felt was a small bulb when I got it 3 years ago. It bloomed that first year and each succeeding year. It is in bloom now (June 2009). The bulb has tripled in size and has two new offsets growing this year. The flowers have a more greenish cast than most photos show. Nice plant!

The particular clone of that species knight star lily which is commercialized in The Netherlands and Germany, respectively produces flowers with particularly broad segments and - is self sterile. However, I received seeds and progeny thereof, by crossing - in both directions that is, using H.papilio as mother plant and as pollen donor - with "Pink Floyd", H.aulicum v.robustum and H.cybister "Chico". These are all DIPS like H.papilio itself. If it is dusted with pollen from TETs then it produces a nice, well-stuffed seed pod as well, but the bulk of seeds will be chaff. However, perform a careful inspection of the fresh seeds and discover the few specimens with a plump, viable embryo (if you are lucky and there are some at all) ;) Those are precious.

This plant is a natural species, not a hybrid. It *will* self-pollinate, and it *will* set viable seed.
A very arresting flower - unusual color and markings, and exceptionally tall inflorescences.
