Start the seeds on the surface of the potting mix, and spray with a bit of 
water occasionally if they are slow to germinate.  Most crinum seeds are 
all too eager to germinate, but some will wait a rather long time before 

I grow mine in full sun in summer.  They can take full sun here at latitude 
40 degrees N.  You are right, use a gritty, freely draining mix and keep 
potting them up into larger containers each year until you can just barely 
move the pot!  I feed and water regularly in the growing season, and I 
actually have many of my big (5-gal and 7.5-gal.) pots of crinums on a drip 
irrigation system in summer when it gets hot and dry here.

Crinum macowanii has a very extensive range in southern Africa.  I have 
plants or seedlings from plants that grew in Zambia and Namibia, as well as 
in the Republic of South Africa.  Thus, some may well be much more 
cold-tolerant than others.  I'd proceed with caution on this score.

I love the flowers of macowanii.  I have pictures posted at URL = 

I also have seedling bulbs of Crinum [bulbispermum X macowanii] and of C. 
[bulbispermum X lugardiae] available this year at URL = 

I don't know what the flowers of these hybrids will look like, so I'm 
awaiting their eventual bloom on pins and needles.  They won't bloom yet 
this year, unfortunately.
