The Garden Goddess
Iris was the goddess of the rainbow in Greek mythology. I have a thing for Greek mythology, and I love Irises. The large, bearded types unfurl at this time of year and they reflect the colours of the spectrum from deepest purple, through dusky orange, egg-yolk yellow and the most delicate of blues, to the brightest of whites. They comprise of standard petals, which are carried aloft over the graceful fall petals, which arch downwards. From the upper bases of the falls grow groups of fuzzy hairs called beards and from this the bearded Iris gets her name. Even the foliage is attractive: large pale green swords that shoot straight upwards from the earth.
Bearded Irises love full sun and prefer to have their fleshy rhizomes (the underground stems) near the soil surface so they can take full advantage of the sun’s warmth. They actually prefer a more impoverished soil, so if your soil is a bit thin and dry they may be perfect for your garden.
As the clumps become overcrowded the centres die out. Dig them up immediately after flowering and chop them into single healthy rhizomes, each with a fan of leaves. Shorten each fan with scissors by about half, then replant about 30cm apart in another sunny spot so that the rhizomes are just visible under the surface. Although they like drier conditions make sure they are watered in and looked after for a few weeks until established. But really you don’t need to do much to them. Overly enriched soil is not a friend to the iris, which might decline to flower in such conditions. My best flowering plants are in the driest, most sun-baked part of my plot!
But for those who have shadier gardens and boggier conditions try the non-bearded Iris sibirica. I have one in a sun-dappled spot by a water feature. Its leaves are greener and grassier, which complements the water, and it has lovely rich blue flowers which look particularly nice in the shade. I also like Iris ensata, which I plant by my pool at the water’s edge. It’s also a good choice in borders if you garden on richer soil than mine.
So, invoke the power of the Goddess Iris in your garden, and enjoy the rainbow of colour.
Happy gardening,
