Check these "Albany" asiatic lilies out. They were planted (3 bulbs) in spring of 04, one of the first things I planted, they bloomed, typical for a first year plant, nothing special. 2005 we had an addition put on and redid the siding here, digging, construction workers, everything to the right of the walkway was destroyed. These didn't grow at all in 2005, and probably had their bulbs torn up in the ground.

2006 they came back, weakly, then here in 2007, what a show. The construction may have even helped them spread.
