What time of the year do Iris bulbs grow? Spring or Summer?

I have "shogun iris" bulbs I planted last fall and so far nothing has started growing. I cant find anything about this particular new breed of iris bulbs on the intranet-- help!

What time of the year do Iris bulbs grow? Spring or Summer?
Iris grow from rhizomes not bulbs and the rhizomes need to "see" the surface (sun). If planted deep like spring bulbs (tulip, daffodil) they have a hard time growing greenery and blooming. They like to be well watered and then left till the soil dries out completely to prevent rot. If you planted them completely under the dirt it may take them quite awhile to poke green leaves through. Folks who mulch iris beds uncover them after danger of frost is over. You might try gently removing some soil to see if your rhizomes are still there and leave the tops of the rhizomes exposed.

Reply:They come up in the spring, bloom most of the summer %26amp; die back down in the fall.





Depending on your location you should see them when days are 70ish %26amp; nights above 40ish.
Reply:A lot depends on your local weather.


June is when they are supposed to bloom.


Hopefully you did not plant too deep.
Reply:Most bulbs need to be planted in the fall. What didi you do for them over winter? Did you mulch them (5-6 good inches?. Don't give up on them this year, they still may make an appereance, but don't expect a whole lot out of them. Most perinnels don't fully mature until their 3rd growing season.
Reply:"Shogun" Iris ensata is a Japanese Iris, they typically bloom May-June. See the link for information on this Iris Genus.





Depending on where you planted it and what the climate is it may not have sprouted yet. Did you plant it in a very shady spot? On the north side of a fence or building? Most Iris rhizomes (not bulbs) should be planted right below the top of the soil with no more than an 1/2" of soil on top, did you possibly plant it too deep? Iris usually don't bloom the first year and many not until the third year. If you haven't seen any signs of growth by the middle of June it probably won't grow.
