Re-flowering Iris danfordiae

Iris danfordiae is notorious for not flowering after the first year. Newly 
planted bulbs do their thing in the spring, but then divide into innumerable 
rice grains that seem never to reach flowering size.

For many years, I've thought that the problem was that the bulbs were planted 
too shallowly, and that if planted deeper they wouldn't split up, hence would 
flower more.

Time for a revision of thinking: yesterday, I was visiting a friend on 
Saltspring Island who showed me with pride a pot of Iris danfordiae flowering 
quite nicely years after the original planting. His secret? A layer of horse 
manure at the bottom of the pot.

It may be that the solution is very simple: you have to feed the beast heavily.
