In the spring on my trip to Oregon and Washington for the
joint Region 13/TBIS meeting, I had planned to spend the day after the meeting
in Oregon at Mt. Pleasant Iris Farm, then at Aitken’s Salmon Creek, and
then the evening with my niece and her family.
Sunday morning, I got on the road only to find the rental
had a leaking tire; Thrifty did a quick exchange of vehicles at the Portland
Airport and I arrived mid-morning at Mt. Pleasant. Seeing that Chad and Dale
were both busy, I headed for the irises. Almost at once, Chad Harris came up
and wanted me to go up the hill to the patio and to see a new iris species he
had in bloom, especially since one flower was fading rapidly.
At this time the new species does not have a botanical
name and goes by the garden name of ‘Azure Blue’. Chad had two specimens
blooming in pots and there was enough difference between the two clones to see
that they had been raised from seed. One of the most interesting things about
this new species is the notches in the standards that locks the standards in
place. Right now the goal is to obtain more seed so more growers can propagate
the plant. Later down the line, the hope is studies will be done to see where
it fits into the genus iris. The current thinking is that it is an unknown
species of crested iris most likely related to I. milesii and I. tectorum;
however, it has resisted setting seed with either one of these groups. The stalks had two flowers in the terminal and one flower in the side branch.
This new species was one of the highlights of my Oregon
and Washington trip. It is not every day that we get to see a new species live
and bloom.
The background of this iris is also interesting. It comes
from the least populated states in India, Arunachal Pradesh, and borders Tibet,
Myanmar, and Bhutan. The climates range from subtropical to alpine and even
tundra.
Travel to the state is not easy, but in 2009 the
plantsman Peter Boardman went on journey through the state. There he took pictures
of an unknown iris. In 2014 a collecting trip was made, plant material
collected, and then that material sat in the post office and customs and was
destroyed. Until I made the trip this spring to Oregon, I was not aware that seeds had
made it to the United States. We should consider this a developing botanical
story with the next chapter yet to unfold.
