Just about 4 weeks ago was my first post about plants on my street. This included some space streetside, where a few doors down from my bloc is a group of iris and daylily planted by one of my neighbors. Here are the now pix 15 May, followed by a short description about their care and following that, the then pix from 20 April –
In bloom on the 15th of May
Iris plants are rhizomes which shot up a paler green cluster of straight firm leaves. In our temperate zone you can leave them overwinter without protection. Given enough space, each year there will be more and more plants and flowers produced.
If you need to divide them or transplant them, it is best to wait until early fall. If you need to do it sooner, then do it after they flower. If you chose to do it after they flower, it is best to wait for them to wither since like tulips they will be producing nutrients for the next year.
