Harpswell Happiness is part of the sibirica family of iris and has pure white flowers with a touch of yellow at the petals base. Each stem will grow to 60-90cm high and can produce between 2 and 5 flowers per stem. They will quickly form into clumps and are suited to most garden types which are free draining. They are happy in full sun or semi-shade. Remember to cultivate the soil before planting and mix in something like bone-meal or well rotted garden compost at this stage. They will need to be split and divided after 3-5 years, which is best done after flowering and before the leaves have died back. Plant rhizomes so the roots sit below the soil surface with a green growth just breaking the surface.
Flowering height: 24-36″ (60-90cms)
