Typha laxmannii is a deciduous, marginal, perennial, freshwater wetland plant with an arching habit. Its light green leaves are upright, strap shaped, are up to 4mm wide and 90cm long. Its brown flowers are monoecious with the female being distinctly separated from the male; female are cylindrical to ovoid, up to 30cm long and borne below the male on long flower stalks. The male which are slender and up to 1.5mm wide whither away once divested of pollen. Its fruit are borne densely upon the pistillate section. the roots of this plant are rhizomatous, which aids its spread.

Typha laxmannii, commonly known as Graceful Cattail or Narrow leaved European Cattail, is native to south west Asia and Europe. In its native habitat it grows in lakes, ponds, channels, swamps and shallow rivers.

The etymological root of the binomial name Typha is derived from the Greek name for this plant, ‘Tufh’. Laxmannii is named for Erik Gustavovich Laxmann (1737 – 1796), a Finnish clergyman, scientist and explorer.

The landscape architect may find Typha laxmannii useful for pond, streams and lake planting. This plant is suitable for use as part of a Sustainable Urban Drainage Systems (SUDS). It may used for planting in drainage ditches, swales and balancing ponds. It should be noted this species of Typha can be invasive, spreading by rhizomes.

Ecologically, Typha laxmannii provides food and nesting sites for waterfowl, marsh birds and small mammals.

Typha laxmannii prefers wet, fertile soils. It tolerates most pH of soil. It should be planted in water to a depth of 0cm to 150cm.

Typha laxmannii requires little maintenance. Large clumps may be divided in spring. Unwanted plants may be removed either mechanically or by the use of appropriate herbicide. Structures may be installed to prevent its unwanted spread.

Typha shuttleworthii is a deciduous, marginal, perennial, freshwater wetland species. Its light green leaves are upright, strap shaped are up to 1.5cm wide and 1.5m long. Its dark brown monoecious flowers are cylindrical, are up to 30cm long and borne on long flower stalks. Its roots of this plant are rhizomes which aids its spread.

Typha shuttleworthii, commonly known as Reedmace or the Broadleaf Cattail, is native to Central and Southern Europe to south west Asia. This plant is under threat in a number of its natural environments.

The etymological root of the binomial name Typha is derived from the Greek name for this plant, Tufh.  Shuttleworthii, we believe, is named after the botanist Robert James Suttlewort (1810 – 1874), reader feed back on this would be welcome.

The landscape architect may find  Typha shuttleworthii useful for pond, streams and lake planting. This species of Typha is not as invasive as others. It is suitable for use as part of a Sustainable Urban Drainage Systems (SUDS) in the form of drainage ditches and swales.

Ecologically, Typha shuttleworthii provides food and nesting sites for waterfowl, marsh birds and small mammals.

Typha shuttleworthii prefers wet, fertile soils. It tolerates most pH of soil.

Typha latifolia (13/09/2011, Southend On Sea)

Typha latifolia (13/09/2011, Southend On Sea)

Position: Full sun    

Flowering period: Summer

Soil: Silt, up to 1m water depth

Eventual Height: 2.5m

Eventual Spread: 0.6m

Hardiness: 6a, 6b, 7a, 7b, 8a, 8b, 9a, 9b

Family: Typhaceae

Typha latifolia is a vigorous deciduous, perennial obligate wetland species. It has upright, strap shaped leaves which are 2-4-cm in width and 1.5-3m high.  It is a marginal water plant, growing in silt deposits in a depth of water of 0.75 – 1m, it prefers fresh water but will grow in slightly brackish marshes. The stems of the plant bear long flower spikes with an upper male staminate section and a lower female pistillate section, the flowers being monoecious.  The flowers are borne in late summer and come in the form of dark, creamy, terminal flower heads followed by  dark brown sausage shaped seed heads. The foliage is mid green in spring, summer and autumn, with brown fruits being produced during the autumn months.  T.latifolia regenerates vegetatively through rhizome sprouts and sexually through seed germination. This plant prefers a sunny a site with partial shade, it will not survive in a shady location.

Typha latifoliacommonly known as the Bulrush, Common Bulrush, Broadleaf Cattail, Common Cattail, Great Reedmace, Cooper’s Reed and Soft Reed, is native to North and South America, Eurasia (including the UK) Africa, New Zealand, Australia, India. In Australia and Hawaii it is considered an invasive weed. It has been found in a number of climates from humid to subtropical and is able to survive at elevations from sea level up to 2,300 meters. Typha latifolia is often found at the edge of bodies of water mainly ponds, marshes and permanently wet drainage ditches. The mature flower stalks are said to resemble the tail of a cat hence the common name Cattail. Surprisingly, once established, the rhizomes of this plant will tolerate prolonged period of drought, two years have been recorded in one instance. Typha latifolia is entirely edible, the Native Americans ate the newly emerged sprouts (as a green vegetable) in spring, the flower stalks (boiled) and the pollen (added to other flours).

The etymological root of the binomial name Typha is derived from the Greek name for this plant, ‘Tufh’. Latifolia is derived from the Latin Latus meaning ‘broad’ and folius meaning ‘leaf’ (broad leaf).

The landscape architect may find Typha latifolia useful in a native wetland planting scheme. It is suitable alongside a water body such as a pond, artificial lake and slow moving rivers. It is also suitable for use as part of a Sustainable Urban Drainage Systems (SUDS) in the form of drainage ditches (swales), attenuation ponds and other suitable water features. It may also be used to treat polluted water.

Ecologically Typha latifolia provides food and important nesting sites for waterfowl, marsh birds and small mammals.

Typha latifolia prefers fertile muddy soils and can survive in acidic to calcareous soil pH. It prefers waterlogged soils, preferably to a depth of 0.75m to 1m.

Typha latifolia require little maintenance. If a tidy appearance is required the removal of dead foliage and old flower stems may be done in spring. Due to the vigorous nature of this plant it may be necessary to have a management program in place to keep stands of this plant in check, removing unwanted plants either mechanically or by the use of herbicide (when the plant is in flower). If appropriate, this species may be managed with fire.
