Bearded Iris Progress Report. 7.19.14

Historic Bearded Iris Raised Bed #2

Historic Bearded Iris Raised Bed #1
I really messed up the historic iris beds last year.  I gave them lots of TLC, compost, lime, coffee grounds, eggshells, and a small nitrogen boost.  Growth was lush and thick.  They looked great going into winter.

Then this Spring, they grew lush again, then were hit with multiple waves of bacterial rot.  Clump after clump was affected, with some losing almost all of the leaf fans, some losing a few.  A few were lost entirely.  Some have one tiny shoot remaining.

Meanwhile, the irises I planted in the fence-row, and in borders by the house, were entirely neglected and had no bacterial rot.  They bloomed reasonably well.

Realizing the TLC was the problem, but not knowing what aspect of TLC, I left the historic iris raised beds alone for the rest of Spring and early summer.

Meanwhile, this Spring I received an order of several varieties from Old House Gardens, and this week a partial order from Schreiner's.  I would not have ordered them, had I known the bacterial rot would be so challenging, but those orders were from some time back.

Today I weeded and culled Historic Bearded Iris Bed #2.  Culls:  All but one cluster of Cherry Garden.  That variety did survive the epidemic, but blooms too early, in the rain, which destroys many of the flowers.  The bloom time is short.  I still like it, very pretty, so kept one cluster.   I culled Romeo, which may be mislabeled, was ugly, bloomed only in Fall for 2 years, when the flowers are made even uglier by the rains.  Some varieties came through the epidemic like champions - Loreley, Sunny Disposition, and some fans of Los Coyotes.  The new rhizomes of Owyhee Desert and Gay Geisha barely survived, but have some small baby shoots.  The rest were in between.  From the areas where I removed rhizomes, or where there was no longer a cluster, I dug out the soil, replacing with powderized mole hill soil, without supplement or compost.  I planted the replacement Gingersnap  from Schreiners, where the prior one died.  I planted Mrs. George Darwin, Dauntless, and Crimson King where others were removed, in the replacement soil.  Dauntless has a suspicious area, may have bacterial rot.  Will try anyway.  I removed the weeds and all of the sedum, so there would not be plants shading the rhizomes.    I watered them in.  Debated doing that.  The summer days are hot, sunny, and dry.  I hope that means no further epidemic, and the watering helps them establish.  But no other TLC.

I pulled just enough weeds from bed #3 to plant the new variety "June Krauss".  That is also in un-enriched replacement soil.

I pulled some weeds and removed clusters of Chinese Chives from Historic Iris Bed #1. I liked the Chinese Chives there but they take too much room.  I dug out the first row, including the tiny remaining sprout of Shannopin and small sprouts of Flavescens and Alcazar.  I replaced the soil with unimproved soil, and replanted those 3 plants.  They may not have enough growth to bloom next year.  If they produce enough for growth the following year, that will make me happy.  I removed a few more weeds, watered the rest lightly because the soil is too hard to get the weeds out, and watered in the replanted irises.

I don't want to lose the Alcazar.  I hope it survives.

The Chinese chives are sitting in the shade.  They need a new location.  They are seedlings from my parents' yard, so I don't want to lose them.

Historic Iris & Culinary Herb beds, progress report.

Historic Iris / Culinary Herb bed #2
This weekend I move more irises to the second raised bed.  I learned from last year's experiences.  Moving late Spring / early summer did not result in any negative consequences, and the irises I moved at that time flourished.

The varieties I moved from Vancouver were:  Cherry Garden 1966 (small variety), Pink Bubbles 1980 (small variety), and Gay Parasol 1973 (tall variety).  Any iris more than 30 years post introduction year is considered historic.  That makes me historic too.  I also added Los Coyotes 1992 - not historic.   I planted woolly thyme, which it looks like will stay very close to the ground, which I want.  The marigold sweet alyssum seedlings are about 1 inch tall.
Historic Iris / Culinary Herb bed #1
The first Historic Iris / Culinary herb bed.  Still in Bloom:  Quaker Lady, Iris pallida dalmatica, Shah Jehan, and Iris flavescens.  Iris flavescens is especially florifeorous.

Roman chamomile is too rangy.  After bloom, it will have to go elsewhere.  Greek oregano is also too tall for the small iris plants.  Lime thyme, French thyme, and sweet alyssum are ideal size.

Iris Raised Bed, heritage Irises

Heritage iris and culinary herb raised bed
 Heritage iris and culinary herb raised bed.  Now I wish I thought of this before.  They go together very will

Caprice.  The photograph color is not the same as the flower.  In person is is more of a rosy red, not so blue.  Nice sweet fragrance.  In the literature this is described as a grape fragrance.  That is not far off from reality.
Quaker Lady.  Also a nice sweet fragrance, floral.

Pallida dalmatica.  Also, sweet grape - like fragrance.  Sweeter than grapes.

Sold as Honorabile but Historic Iris Preservation Society states most likely Sans Souci.  No fragrance, which I knew when I ordered this variety.  I liked the appearance, and in person it is better than I anticipated.  Ideal little iris for this bed.  I don't know what I should call it, but leaning towards Sans Souci, since that is probably the right name.

Flavescens.  Also unscented, and also ideal for this bed.

Helen Collingwood.  I think I already posted that so will hold off doing so again.  Also nice floral fragrance.

Iris/herb bed #2 is also coming along nicely.  Both got a dusting of crushed eggshells this weekend for calcium.

Caprice 1898

Quaker lady 1909

Pallida dalmatica 1597

Honorabile 1840 (Sans souci? 1854)

Flavescens
