Siberica, Germanica, Pacific Hybrids – all welcome here
This month I’m going to talk about Irises as I’ve been thinking about just how valuable they are in the garden.
They are versatile, colourful plants and I’m happy to have plenty in various conditions. They bear bright flowers on slender stems so they’re very handy for anyone planting a border; you can have them drawing attention at different heights without using too much space at ground level. The detail within the flowers can be stunning, with fine veining, marbling and contrasting colours.
I’ll begin in the wet with the sibericas. These irises are all shades of blue, usually planted in pond margins. I use them in borders too, as long as they have reasonable soil they will be fine. In one bed I’ve got them with the pink geranium, ‘Rozanne’ and the colour makes me smile every time I see it. If you enjoy pink / purple / blue this combination is well worth a try.
Irises are stately plants that can be used as part of a carefully designed border or drifted through more ‘natural’ planting schemes. There really is one for every place in the garden. If your soil is well drained and sun-baked, germanicas are the species to look for. These are the ‘bearded’ Iris that grow to about 1m tall and need their rhizomes baked hard each summer. I’ve just planted ‘Kent Pride’ which has a striking peach and yellow flower. I’m looking forward to seeing it flowering next year.
The choice of colour is almost endless, especially as the Pacific Hybrids are being cultivated. This group of plants derives from cross-breeding between 11 different types of Iris, and they are extending the choices for planting colours, situations and combinations. I have these on woodland edges and shady borders as I’m experimenting with how far I can get them to adapt to all corners of our Dartmoor valley. I’ll keep you posted with the results.
