Rainy Side Notes
Only a handful of the Juno iris can be successfully grown in our Northwest gardens, and this one is the most vigorous of them all, and also the most widely grown. The first spring they came out of the ground after fall planting, they stole my heart. I like the fan of foliage and that the flowers sit on top of the fan and in the axils of the foliage. Unfortunately, the slugs like this cute little number too. Next year I will be more vigilant on protecting the handsome foliage from mollusk attacks.
Introduced to England in 1902 and classified as a subgenus Scorpiris, taxonomists may eventually reclassify them into a separate genus of their own.
Most Junos hail from desert conditions and thrive with very little water and lots of heat. In the wild, this Juno grows on stony or grassy slopes and can make a fine rock garden specimen. Iris bucharica can be successfully grown in our Northwest climate if you provide adequate drainage and protection from slugs.
Carefully divide clumps every few years to avoid damaging the fleshy roots after the plant has gone dormant.
Some parts of this plant are poisonous.
