Cyrtanthus species and hybrids Intro.TOW

Hi all,

Angelo's complaint mirrors mine exactly:  Cyrtanthus elatus never bloomed 
for me in all the years that I had it.  I have to say that I threw out my 
last bulbs of C. elatus several years ago!  Never again will I waste good 
greenhouse space on Cyrtanthus elatus.

C. sanguineus also blooms reliably here every year for me.  I also find 
that it never has set seed.
My bulbs of C. mackenii cooperi also bloom just about every year. Both 
these species have filled their respective pots to overcrowding with 
offsets, several of which also bloom.

A large bulb of C. obliquus that I bought a year or so ago is still large 
and seems pretty healthy, but has not so far bloomed for me.  Three large 
bulbs of C. falcatus, bought at the same time as the obliquus, have 
produced only one single scape so far.

Small bulbs of C. montanus are slowly growing toward what I hope will 
eventually be blooming size.

Small seedling bulbs of C. brachyscyphus are just sitting there, perhaps 
because they are too crowded in their original communal seed pot.

I have lost 100 % of seedlings (from seed) of CC. breviflorus and 
flanaganii.  On the other hand, C. obliquus seedlings (from seed) are doing 
very nicely, and I should probably pot them up into individual pots this 
winter before they start to grow again.

I grow all of my Cyrtanthus in pots, of course.  They would not survive 
long outdoors in the ground in my climate.  I pot all of them in gritty 
mix:  Promix + sand + granite chick starter grit ( 2 : 1 : 1 ).  They spend 
the winter inside a greenhouse, almost always completely dry; in summer 
they go outside, in full sun.  This may not be the best way to grow 
Cyrtanthus, it is merely the way I try to grow all of my Cyrtanthus.  It 
doesn't always work.

I look forward to this discussion because I would like to be able to grow 
more Cyrtanthus species and to grow the tough ones more successfully (at 
least more successfully than 100% mortality!)
