I really like that the Japanese Higo iris are such a big feature of our December meadows yet they almost certainly descend from the Japanese quest for a perfect, single bloom as a focus for contemplation. It is such a wonderful contradiction – that quiet refinement, simplicity and elegance that the Japanese traditionally bring to flowers generally and the wild abandonment of our Tikorangi meadows.
Higo are not a separate species of Japanese iris. They are hybrids, bred over 500 years, originating from Iris ensata. There are three groups of iris from these breeding lines – Edo, Higo and Ise but the best known are the Higo. Our Higo were given to us by Auckland plantsman, Terry Hatch of Joy Plants, and apparently originated as wild collected seed. Mark had a discussion with Terry about wanting to try naturalising Higo by the stream but the finely bred, named cultivars were not sufficiently robust to survive in a situation of benign neglect. Terry offered up a tray of about 700 germinated seedlings which seemed a bit of overkill at the time. Now we bless him every year. Not all 700 survived, I hasten to say, but we had plenty to play with.
Because our plants are all seedlings, we have a fairly wide range and some clearly show their I. ensata heritage. Others are pure white, pink, almost pure blue and the whole range of violets, purples and lilac.
I see the oldest plants are now in their ninth year or so of being planted on the banks by the stream and ponds and they perform reliably every year. Given they have stiff competition and receive absolutely no care or intervention, that makes them very robust plants. I tried some in a mixed border at one stage but they were too strong a grower with leafage that swamped out surrounding plants during summer and autumn so I removed them.
A few years ago, I planted the last of the neglected pots from the nursery down in the area we call the Wild North Garden and this year, some are starting to bloom. They are much more rewarding than the Louisiana iris we grow where the leaf to bloom ratio is too high.
From mid to late November through until Christmas, the flowering of the water iris is such a delight. Like over the top butterflies, they float in the air above a sea of buttercups, dandelions, daisies and wild grasses and they truly make my heart sing.
