This plant deserves the full article all of its own. There are 3 varieties of Iris that are generally considered for being true aquatic plants for growing all year round within the shallows of a pond and i consider it to be extraordinary to have a group of Marginals without having at least one of these beautiful plants growing in the pond. The most important variety for the average garden pond is Iris Ieavigata (Japanese Water Iris). The three petalled blooms are somewhere in the region of about 5 inches across and they are borne on 2 ft. high stems. The 1st flowers normally start to open in June and are clear blue in colour having a yellow line down the middle of every petal. A further flush of blooms may appear in September depending on the climate that you live in.

There are a number of varieties that you can select from 'Snowdrift' (white with 6 petals), 'Dorothy' (blue with a white line down the centre of each petal), 'Variegata' (blue, leaves variegated yellow and green) and the hybrid I. 'Rose Queen' (rose-pink).

The planting depth for I. laevigata and its varieties is 0 - 3 inches. I.pseudacorus (Yellow Flag or Yellow Water Iris) is more vigorous and taller than I. Iaevigata. The foliage is 3 - 4ft. lond and the yellow flowers are on stems that can reach as high as 3 ft. The variety is too course for ordinary garden ponds but the variety 'Variegata' (2 - 2.5 ft. high) with its more restrained growth habit and cream leaves edged with green makes it an excellent choice. Other varieties include 'Sulphur Queen' and 'Bastardii'. The planting depth for I. pseudacorus and its varieties is 2 - 4 inches.

The third aquatic species is I. versicolor (American Blue Flag). This is mostly a restrained plant for your smaller pond. Its leaves are 2 ft. long and the flower stalks are 1.5 - 2 ft. in hight. The violet blue flowers begin to show in June or July and they have narrow petals blotched with gold at the base. The favored variety is 'Kermesina' with claret red flowers flecked with white. The planting depth for I. versicolor and its varieties is 2 - 4 inches.

Propagation: To propagate the individual plants, all you need to do is divide the clumps when the flowering has finished and your plants will thrive.

That virtually covers everything I want to say about this stunning plant. I do hope that I haven’t gone on too long about the Iris, but I do feel strongly them. From a personal point of view, if you haven't got an Iris or two growing in the pond then you really should add them. You certainly will not regret it. The vibrant colours and sizes of these plants will amaze you along with any visitors that you may have. I could have made this article a whole lot longer but I do not want the readers getting bored. Please, just give the Iris a chance.

A lot of my time is spent in my garden. I have been searching for help on how to develop the perfect pond habitat for the fish which I will stock it with without much luck. To obtain the help I will want I have decided to use a company called Gardener London. Up to now they have given me all the help and advice that I have asked for, as and when I ask them for it.
