Cyclamen species I through Z are found on this wiki page.
Cyclamen intaminatum comes from western Turkey, where it grows mostly in deciduous woodland sites. It is one of the smaller species so is usually grown as a container plant, even though it is winter-hardy down to at least 20 degrees F. The plants shown were grown from seed and are four years old from sowing. These plants have plain green leaves, but marbled leaves are also known. The first photo is from Jane McGary and the second from Mark Smyth. Photos three, four, and five are from John Lonsdale.
Cyclamen libanoticum comes from a very small area in Lebanon. Its affinities within the genus Cyclamen are open to debate. This is the first bloom on a batch grown from seed (February 2005). Photo one by Jim Shields. The second photo is by John Lonsdale
Cyclamen mirabile is an autumn blooming species very similar to Cyclamen cilicium. It is found in woodland and hilly rocky places in southwest Turkey. It has pale to deep pink flowers with toothed petal lobes and a stain around the mouth. The heart-shaped leaves, which appear about the same time as the flowers have a hastate pattern in grey-green, cream or silver and scalloped margins. Sometimes the new leaves are flushed pink. Photos 1-4 from Mary Sue Ittner. Pictures three and four taken a year later of a plant grown from the same seed batch as the ones above shows flowers in a close-up and a more developed plant with beautiful leaves. Photo five is by John Lonsdale.
Cyclamen mirabile ‘Tilebarn Nicholas’ , a selection from Peter Moore, has leaves with a green tree shaped center surrounded by a silver band. The young leaves have a pink tinge that fades with time. First photo from Mary Sue Ittner, second from John Lonsdale.
Cyclamen persicum is the species used for all the large-flowers cultivars that are available for purchase. It is from the eastern Mediterranean where it grows in open rocky areas and in scrub. It blooms in winter or early spring with fragrant plain white, white with a carmine mouth, or pinkish carmine flowers. Leaves are variable. Photos by John Lonsdale.
Cyclamen pseudibericum is a very attractive species from Turkey. It has purplish carmine large fragrant flowers with a dark stain around the mouth and a white rim. The heart shaped leaves have toothed margins and sometimes are beautifully marked with silver and green. The illustrated plant is blooming for the first time after being grown from seed and is blooming early (February 2004) since it is usually a spring bloomer. Photos one and two by Mary Sue Ittner; photo three by John Lonsdale.
Cyclamen purpurascens is often evergreen, but can lose its leaves in late spring for a short time. It is native to mountain woods and rocky places in the eastern Alps. Flowers appear from late summer to late autumn and are pale to deep carmine and do not have auricles around the mouth. It is nicely scented. The first photo was taken by Mary Sue Ittner who did not find it as easy to grow and flower as some of the other species she grows. It was plagued by mites. She read that it benefits from being kept cool and not allowed to dry out in summer, being planted deeply (see contrasting note below), and being well mulched. The second by Hans Joschko. He wrote: These plants grow without any problems in my garden from many different locations: Lake Lugano (Italy), Lake Garda (Italy), the woods near Vienna (Austria), Savoyen (France), Istria (Croatia), and Lake Plitvice (Croatia). Photos three, four and five are by John Lonsdale.
The photos below by Giorgio Pozzi, September 2009, are from wild specimens collected and grown in the garden. In northern Italy they need to be planted not too deeply, in a very soft and rich compost in the ground or in pots where it is easier to collect the seed capsules that form inside the coiled stems. The first photo illustrates plants with a tuber that is partly out of the ground and in the second there are seed capsules.
Cyclamen purpurascens forma album is a white form that has only been found in the wild a few times over the years. Photo by Hans Joschko who writes: "I have two of this really rare plant, and I hope that it multiplies well in the future."
Cyclamen purpurascens forma carmineolineatum named by P.A.H. Hendrikx in 2000 is a new form that closely resembles C. purpurascens forma album Grey-Wilson. It is distinguished from the latter by the presence of a distinct carmine zone around the mouth. Photo from Hans Joschko who writes: "I have found only one plant of this type in a large population of Cyclamen purpurascens in the French Alps (Savoyen) opposite Mt. Blanc."
Cyclamen repandum, a species from southern Europe, is one of the last species to break dormancy for me, sometimes not until winter. The leaves are heart shaped with a narrow and deep sinus making them almost triangular. They are angled and lobed and often toothed. Flowers often appear with or soon after the leaves and are white to pale or deep pink, often with a pink or purplish red zone around the mouth, or carmine magenta or reddish purple. Petals are sometimes twisted. Photos by John Lonsdale and Mary Sue Ittner. The last photo shows the tuber on a 1 cm grid. In spite of the signs of new shoots when repotting, it will be months before any signs of life appear above the surface. In her California garden leaves don't usually show until December.
Cyclamen repandum ssp. peloponnesiacum from Greece has silver splashed leaves or sometimes speckled leaves and pink flowers with a deeper carmine-pink zone around the mouth or intense carmine-magenta. First photo from Mary Sue Ittner of plants blooming in Northern California in February. Second photo by John Lonsdale.

Cyclamen repandum ssp. repandum grows in dappled shade in leaf litter, rock crevices, or at the bases of trees. Leaves are green with a grey-green or silver hastate pattern, but without flecking. Flowers are carmine-pink or carmine-magenta. Grown from seed not designated by subspecies, this plant seems to fit the description for this subspecies. Photo by Mary Sue Ittner of plants that start to bloom in Northern California in February.
Cyclamen rohlfsianum is the most tender species, originating in Libya. It is autumn flowering and has large lobed leaves that are ususally wider than long and are deep green with silver patterns. The flowers are distinctive as they have a protruding cone of stamens. The tubers are large and uneven and the flower stalks coiled from the base upwards as in Cyclamen graecum. Photos 1-3 were taken by John Lonsdale. Photos 4-6 were taken by Dylan Hannon of plants started from seeds from the Cyclamen Society in 1993. It only gets better with age and is a very reliable pot subject. It is kept dry all summer. Under tree cover it has withstood brief spells in the upper 20s F without blinking.
The photos below were taken by John Lonsdale, Mary Sue Ittner, and Dylan Hannon showing various leaf forms of the species. That the seedlings showed variation is interesting since selfing in plants usually does not produce much apparent variation.
Cyclamen trochopteranthum is a species in the Cyclamen coum group from southwestern Turkey where it grows in rocky areas, deciduous woodlands, and scrub. It has sometimes been called Cyclamen alpinum. Flowers occur in spring and vary from pinkish carmine to white with a darker stain around the mouth. The petals are twisted, like a ship's propeller. The leaves are rounded or heart shaped with shallow toothing and silver green markings. Photos by John Lonsdale.
