Spice up your colour palette with the punchy heat of Iris sibirica 'Colonel Mustard'. With petals in two shades of mustard (Dijon and English) it’s clear how this handsome creation got its name! Burnished bronze, copper and gold tones bring a cosy warmth to a planting scheme, providing an eye-catching contrast against blues and mauves. Look closely and you'll see that these flags feature their own little hint of mauve—not only do these blooms feature their own little contrast, but they effortlessly tie in harmoniously with any purples surrounding it.  

You can plant hardy Iris sibirica 'Colonel Mustard' in borders with moist but free draining soil and they will return perennially. As they mature, they begin to spread into larger clumps which produce more flowering stems. Over time, the result is an established clump which provides an impressive, unmissable display of flowers among structural, upright sword-like foliage. Flowering in early summer, this is a great plant for combining with plants like Gladiolus byzantinus, Geranium or Geum.
