Very few flowers in the garden can be described as true black, but this elegant iris comes remarkably close with its inky purple flowers and contrasting golden veins along the falls. Foliage is grey-green with narrow, strap-like, arching leaves. Creates a stunning display in any garden. Combines beautifully with other dark-flowering plants or create a striking contrast with white, such as Leucanthemum vulgare.
Iris takes its name from the Greek word for Rainbow, referring to the wide variety of colours that they are available in. There are over 300 species in the genus Iris, and they are much loved by many gardeners due to the colourful displays they create and the elegance of the flowers. They also make excellent cut flowers.
Buying Perennials from Jacksons Nurseries
At Jacksons Nurseries we lightly trim back our perennials after flowering to ensure that the plants remain neat and tidy whilst in the pot. The more tender the plant the less we cut back to help protect exposed stems from winter frost. Depending on the plant variety we will then prune back further in spring once the risk of the more severe frosts is over.
As a result, depending on the time of year you buy perennials, they may not look like images showing their ‘prime time’ in flower and looking at their best.
From late autumn onwards and dependent on variety, there may be very little visible above the soil except for a few cut back dormant leaves or stems. It is perfectly normal for dormant plants to look like this from autumn onwards, they will however burst back into life in spring.

Perennials are described and classified differently by different gardeners but all would agree that they are plants that come into flower every year from early spring to late summer, the exact time dependent on variety and most die back to ground level in autumn and winter.
As for all plants, soil preparation is time well spent. Dig over the area to be planted ensuring that the ground is free draining. If not then you may wish to either consider planting in a different spot or raising the level of the planting area by adding additional topsoil, well rotted garden compost and/or well rotted manure. Add ‘Fish, Blood and Bone’ fertiliser or a high potash fertiliser to encourage good root growth and development.
It’s always a good idea to plant a few of the same plant together, we recommend planting in 3’s or 5’s to provide a bold effect but allowing them plenty of room to develop.
Always check eventual plant heights when planning borders to ensure that the taller plants are at the back (or at the centre of an island bed) followed by the medium and then smaller low growing plants.
Remember to deadhead perennials after flowering, trim back lightly in autumn as required to tidy the border and if necessary trim again in spring once the risk of heavy frost has passed.
If perennials get too big, start to flower less and less or if it seems to be dying off from the centre, consider dividing the plant but always check that the particular variety is happy to be divided and that you divide at the right time of year for the plant.
By using this simple guide and a little time, perennials can make an absolutely spectacular difference to your garden.
