Pastel beauty, the Peacock Butterfly™ Uncorked Siberian Iris (Iris siberica 'Uncorked') is a beardless Iris that features a kaleidoscope of yellows, periwinkles, deep purples and overall smokey hazy look on the many layers of petals!
Held aloft on strong tall stems and surrounded by a backdrop of grass-like green foliage, these form dense clumps in moist to wet soil around your landscape! The colorful blooms look fantastic in any garden color scheme or in any floral arrangement!
Uncorked Siberian Iris do very well in moist soil and form dense upright clumps that reach a tidy 2-3 feet in height and width that allows any sized yard to accommodate them. The rhizomes are very cold-hardy, handling down to zone 3 winters and up to zone 9 summer heat!
Planting and Application:
Siberian Iris are fantastic ornamental grass alternatives, great for edging and vertical texture throughout pollinator, perennial and cottage beds and borders. Container and balcony gardeners can enjoy these early summer blooms in moist pots and planters in the sun, while larger properties can plant rows and en masse plantings for eye-catching displays and erosion control!
Great along water features and pond edges, create beautiful water gardens at the end of where your gutters drain or Rain Gardens in that soggy low spot of your yard! As border plants, the green foliage becomes fantastic backdrops for later emerging plants, looking handsome until frost!
- Muted Lavender, Yellow, Purple & Periwinkle Hues
- Grassy Green Upright Foliage
- Pollinator Friendly
- Waters Edge, Containers, Beds & Borders
- Great Cut Flowers & Specimen Plants
