My potted walking iris (new last fall) did not bloom but one stem has bent over and a new small plant has started. What should I do with the new plant?
Walking Iris may be more suited to growing in the ground.
The new plantlet grow would normally fall to the soil and root and continue to grow in the garden.
This is how this plant get's it's name as it spreads or 'walks' through the garden.
You can plant the new plantlet into another pot if you like.
Here is a link with more information.
