This plant deserves a full article all of its own. You can get 3 species of Iris which can be considered for being true aquatic plants for growing all year round in the shallows of a pond and i consider it to be extraordinary to possess a collection of Marginals without having one of these striking plants growing in your pond. The most important variety for the normal garden pond is Iris Ieavigata (Japanese Water Iris). The three petalled blooms are somewhere in the area of about 5 inches across and they are borne on 2 ft. high stems. The first 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 environment that you live in.
There are a number of varieties which you can pick from 'Snowdrift' (white with 6 petals), 'Dorothy' (blue with a white line down the centre of every petal), 'Variegata' (blue, leaves variegated yellow and green) as well as 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 which can reach as high as 3 ft. The variety is simply 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 variety is I. versicolor (American Blue Flag). This is a restrained plant for the 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 appear in June or July and they have narrow petals blotched with gold on 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 want to do is divide the clumps the moment the flowering has finished and your plants will thrive.
That virtually covers all that I want to say about this stunning plant. I do hope that I haven’t gone on too long in regards to the Iris, but I do feel strongly them. From a personal perspective, if you haven't got an Iris or two growing in your pond then you really need to add them. You certainly won't regret it. The vibrant colours and sizes of these plants will amaze you as well as any visitors that you may have. I could have made this short article a lot longer but I don't want the readers to get bored. Just give the Iris a chance.
