$8.99
Adaptable, medium-sized iris, that holds fairly healthy foliage throughout the whole season.
6" lilac-blue flowers with darker veins, wider leaves arranged in a fan with dense, groundcovering clumps.
Blooming Time: mid May (flowering season depends on your zone and how quickly the weather turns hot), it warmer zones starts to bloom mid March
Size: 1’ tall x ’ wide clumps, slowly spreads into wider clumps (up to 2' wide)
USDA Zones: 4a to 9b
Culture: adaptable, from full sun half to light/dappled shade, soil should be somewhat drained with decent amount of organic matter - average, clayish, rocky, shallower, organic rich soil. Soil pH should be slightly acidic (or acidic) or neutral for best results. In our fron garden grows in very alkaline soil too, but the leaves are a bit chlorotic (light green-yellowish). Grows quite well in drier shade under the trees.
Moisture Needs: average (medium), medium-dry, medium-moist to moist. Drought tolerant
Origin: China, Bhutan and Koren - temperate and tropical regions
Black Walnut Tolerant: yes
Deer/Rabbit Resistant: yes / yes
Attracts Butterflies or Pollinators: butterflies
Attracts Hummingbirds: no
Pot Size: square 3.5"x 4"deep perennial pot
Plant combination: Due to i's adaptability can be used in variety of different flower beds or conditions. From sunny beds, roof gardens, stream gardens, shade gardens, drier shade under the trees. But since there are many irises for sunny location already, we see the biggest advantage of using it in half shade or light shade conditions (or difficult "transition" zones) with plants like Asarum, Geranium maculatum, Heuchera, Silene virginica, Mertensia virginiana, Phlox divaricata or stolonifera, Penstemon smallii or P. digitalis, Polygonatum, Smilacina, Tiarella, Trillium, smaller ferns, or Carex. From introduced perennials, choose Aruncus aethusifolius, Astilbe chinensis, Astrantia major, Brunnera, Geranium macrorrhizum, G. cantabrigiense, Geranium x oxonianum, Epimediums, smaller to small hostas, Omphalodes verna, Primula, small spring bulbs, Narcissus, etc.
