Hi Dell,

If there were not so much snow between me and the other greenhouse, I'd go 
back and measure that aulicum bulb for you.  However, I'll have to make do 
with a memory guesstimate:  diameter over 2 inches (50 mm) so circumference 
at least 150 mm (6 inches), probably more.  Could be diameter as much as 
2.5 inches, circumference as much as 200 mm for bloom size.

My bloom size bulb (plus offsets) is growing in about a 10-inch pot.  I 
grow almost everything, including this, in my gritty mix:  Promix HP 
Biofungicide + sand + granite chick starter grit in ratio of 2 : 1 : 1 by 
volume.  For general watering and fertilizing, see Bulb Notes, current 
issue; it's with the Clivia.
