Gardeners' Notes:

Negative coriaceous On Mar 11, 2015, coriaceous from ROSLINDALE, MA wrote:

I've never had much luck with these in Boston Z6a. They are very short-lived here (2 years at most) and often fail to flower or even survive their first winter. The summer-dormant "evergreen" foliage comes up in the fall and usually gets hammered by our winters.

I find the foliage is untidy and the habit gawky. I think in the border it's most often an eyesore, especially when it comes up blind. Perhaps it's best relegated to the cutting garden.

Every year I divide the patches and every year more and more . I love them they sailed through this 2011 Texas drought , and to my surprise have multiplied this year also they are coming up with force right now . I cant wait till march when they all bloom .Heat ,drought ,cold ,eager armadillos, nothing phases them they just happily naturalize in drifts wherever I plant the new bulbs .

I have the cultivar 'Symphony' which is the same name as a bearded German iris. Mine is clearly the smaller Dutch iris. blooms are white and yellow.

This plant was a surprise for me. Having just moved in and having no idea of what was in the ground, I was delighted to see this beautiful 20-24 inch scape with three blooms. Each was approximately4.5-5.5 inches in diameter. Blossoms were classic in configuration and white color. This year I am adding 6 new purples and will be propagating the white. Very stately and graceful addition to my garden plan.

We have the blue and yellow Dutch! There is a simple elegance to these flowers and we look forward to their presence every spring.

Positive tulipgarden On Nov 24, 2006, tulipgarden from Pella, IA wrote:

I grew this plant for the first time in 2006. They all came up in the spring and were very showy. Because of the early dry summer they died off quickly. Then due to a mild fall and lots of moisture they have sprouted (November 2006). Use caution when planting to ensure they are at least 8 inches deep to help keep them from sprouting to early.

Neutral JenniferSM On May 2, 2006, JenniferSM from Woodland, CA wrote:

There is no doubt, this is a beautiful flower. But, it only lasts about five days until it wilts, and "poof" its gone! Seems like such a short climax after having sent up its green "leaves" almost for three months prior, which aren't particularly attractive.

Great plant to use for fill among later blooming perennials since it grows up and not out. a big plus for me is that deer leave them alone.

Neutral PurplePansies On Jun 6, 2005, PurplePansies from Deal, NJ (Zone 7a) wrote:

Dutch iris is much smaller than bearded iris and much bigger than dwarf irises (blossom size that is) than dwarf irises like iris reticultata. The most eye catching varieties seem to be the blues and violets with yellow streaks or flashes of an eye that jump out at you. These have proved fairly easy to grow in well drained soil and full sun. No special care required. Minimal winter mulch. On a down side these are NOT FRAGRANT IRISES! Boo hoo I love the fragrant ones..... :)

These pretty much naturalize here (zone 10).

Positive gcaffee On Apr 8, 2004, gcaffee from Roanoke, TX wrote:

I have a bed of blue and white Dutch iris that bloom each year. The blooms seem to pull the stems over however. Is this normal? This year several of the blues came on with two blooms per stem. Very nice. I wonder if I need to feed them or stake them up? This is the 3rd year for this bed and I am pleased with the result.

Positive jcborshard On Apr 17, 2003, jcborshard from Plano, TX wrote:

Anything which thrives despite Texas heat, drought, black clay soil, and neglect earns a positive+ rating here. The blade of the foliage rolls itself into a tube, giving a round appearance like large chives. The purple blooms appear in April. This fourth year some stalks have two. Height is 18" to 24". Bulbs were bought at Home Depot in 1999, but the picture on the package promised blue flowers. Oh, well!
