Tulipa eichleri, commonly known as Eichler tulip or Eichler's tulip, is a species of tulip. It is a bulbous flowering perennial with long green leaves,deep red flowers with a central black blotch, coming from the Caucasus Mountains (between Europe and Asia).
It is thought to be a synonym of Tulipa undulatifolia or a synonym of Tulipa undulatifolia var. undulatifolia by some sources.
Description
It is a perennial that grows from bulbs.
It has a tall, single flowering, upright stem which is covered with short hairs. The plant can reach between tall, or 10 to 12 inches tall.
It has large, broad, strap-like leaves. They are grey-green, or glaucous (bluish-green) with slightly undulating or wavy edges.
It flowers in early Spring, between April and May.
It has large flowers, one of the largest flowers of all the species tulips. They are bell shaped, or goblet-shaped, They don't have sepals, petals or bracts, just five simple tepals. The segments are obovate or obtuse in shape. The flower almost resembles the flowers of Tulipa gesneriana but differs in having a pubescent peduncle (flower stalk).
Tulipa eichleri flowers come in shades of red, from scarlet, bright red, orange, orange-red, crimson, to deep red. They also have a dark basal blotch, which is blue-black, or black. The blotch has a yellow ring, margin, or border around it.
The flowers close at night and they can resemble a "Christmas present with a bow on top".
Biochemistry
Anthocyanins have been found in various tulip flowers, such as Tulipa gesneriana, Tulipa fosteriana and also Tulipa eichleri.
The endosperm of the tulip has been studied.
Taxonomy
The Latin specific epithet eichleri refers to German botanist August W. Eichler who found the tulip in the Caucasus.
It has the common name of 'Eichler Tulip' or 'Eichler's Tulip'.
It was first found in Turkestan, and then described and published as Tulipa eichleri by Eduard August von Regel in his botanical magazine 'Gartenflora' Vol.23 on page 193 in 1874.
It was then first cultivated in England in 1876 with bulbs sent by Prof. Eduard Regel.
In June 1932, it was given the RHS's Award of Garden Merit.
In 1982, David Mabberley in Taxon Vol.31 on pages 65-73, William Roxburgh's 'Botanical description of a new species of Swietenia (Mahogany) and other overlooked binomials in 36 vascular plant families'. He then renamed it as a synonym of Tulipa persica (as it was native to Iran).
Then in 1984, P.H. Davis, in 'Flora of Turkey and the East Aegean Islands' Vol.8 on pages 1-632. It was renamed as Tulipa undulatifolia, which was agreed by the botanists at Kew. The RHS considered it to be a synonym of Tulipa undulatifolia , so do the United States Department of Agriculture and the Agricultural Research Service as of 6 August 2013. It is also in the World Economic Plants book as Tulipa undulatifolia, and other sources.
Then in 2013, D. Everett, in his book 'The genus Tulipa, Tulips of the world' by Kew publishing. He cited it as Tulipa undulatifolia var. undulatifolia. This name was accepted by the Pacific Bulb Society.
Although, Tulipa eichleri is still an accepted name by some botanic sources.
Distribution and habitat
Tulipa eichleri is native to temperate areas of Central Asia.
Range
It is found in Turkey (previously known as Asia Minor,) and Iran, and the Caucasus Mountains, including the Transcaucasian region (South Caucasus or Georgia), and Azerbaijan.
Some sources also adds Greece to the list.
Habitat
It is found on dry slopes and in shrubby woods within the lower mountain belt altitudes.
It grows on the steppes of Georgia, with other plant species such as Seseli granivittatum, Teucrium nuchense, Teucrim pollium, Thymus tifisiensis, Scorzonera eriosperma, Psephellus carthialinicus, Carex bordzilowskii, Tulipa biebersteinii and Iris iberica.
Conservation
It is very rare in the wild and is only occasionally cultivated.
It is listed (as part of the IUCN Red List or Red Data Book) as a Georgian Red Data species.
500 seeds have been placed in the Millennium Seed Bank Project.
In Georgia, the locations of many rare species (Tulipa eichleri and Iris iberica) are decreasing in numbers. Especially, near the roadsides and near the settled areas. This is due to the decimation of vegetation cover. Also, the impacts of irrigation systems and the change of use into land for agriculture (to grow cotton grass, wheat, barley, corn, and vines).
Cultivation
It is only occasionally cultivated and generally only grown by specialist tulip growers, as it is also used for hybridization purposes.
