There are plants one waits to grow for a very long time: I have known about this wonderful pale yellow reticulate iris for many a decade. Once or twice I have even been given small bulblets that failed to flourish. Last summer I saw it on a wholesale bulb list for a surprisingly reasonable price (provided you bought fifty that is)....I pooled resources with four other gardeners, and we bought quite a few kinds of bulbs including the requisite fifty
Iris winogradowii...and I got ten for my share, five of which so far have shown some color so far, and the one above has been blooming since February 26. If you are not aware, this is one of the rarest irises in the world, only a few hundred of which persist on its alpine home in the Caucasus. It is well established in European gardens, enough so that you can now get these for a few bucks a bulb if you shop around (and buy quantities, that is)...
It is reputedly quite sensitive to heat, so I have placed it on the north slope of my rock garden under towering Scots pines where it grows alongside many ferns, primulas and saxifrages. Here's hoping it likes the spot and clumps up. It's progeny,
Iris x 'Katharine Hodgkin', quickly forms dense clumps for me!

Here's a closeup of its cousin, Iris danfordiae, from Turkey. Actually, this is the standard form in cultivation which turns out to be triploid, and therefore sterile. I have found it stays quite perennial and reblooms in my garden planted among
Fritillaria,
Calochortus other iris and a wealth of other bulbs in my blue gramma grass (Bouteloua gracilis) meadow.
I dote on the purple, blue, lavender and other cool blue hues of typical Iris reticulata and its brethren. What better companion colors for these than yellow? Strike up the melody and bring on the yellow reticulates!
