Gardeners' Notes:

Positive pegster57 On May 29, 2013, pegster57 from Charlottesville, VA wrote:

I grow this iris in hot, humid central Va and it is one of my more vigorous irises. It is in full sun in a raised bed with sand added to the soil (we have red Davidson clay here) and it only took 2-3 years before it took off. The flower itself is unremarkable, imho. The tan standards always look like dirty laundry to me. Perhaps this is more pronounced since it is growing next to Helen Collingwood which has the same color falls but white standards.

A nice looking iris that starts blooming very late in the iris season, making it even more desirable in the garden - one of my absolute favorites.
