    Default Leptotes bicolor

    A member of the Cattleya Alliance and closely related to Sophronitis, Leptotes are found in Brazil and Paraguay as cool to warm growing epiphyte. I grow it intermediate. It has terete leaves with large flowers for the size of the plant. I am growing stick mount. I give it a short rest once it's flowers drop.

    That is beautiful.

    Do you consider it a fast grower?
    I have mine mounted on cork panel and has been a VERY slow grower. I have had it since 2002 and it only has about 3 or 4 new leaves at any given time. And only half the leaves bloom.
    To its credit, it is still alive after all these years. It has survived frost, heatwaves, grasshopper infestations, etc.

    I have only had this for about 2 years or so. No, I wouldn't consider it a fast grower. Here is a plant pic from last year, at this time. Edit: looks like it has grown 3-4 new leaves.

    Pretty! I like the waterfall shape of the plant and flowers.

    Great looking plant - and one I hadn't heard of before. I also like seeing a little snippet of your growing area behind the plant.

    REssurecting an old post, My leptotes bicolor is blooming now, the buds are just opening and the flowers appear to be upside down, the lip is at the top! will it correct itself as the flowers open or has my little guy had a brain fart LOL it has 3 flowers on one stalk from on eleaf and seemed to be developing normally until I see the buds opening, I have not moved it.

    Maybe I can seel it as a new breed, confuscious leptotes bicolor

    Carrie many orchids have the lip on the top They are referred to as non-resupinate. If you look back at my second pic, the 2 upmost flowers are non-resupinate. This article you might find interesting...

    Pronounced re-soup-i-nation, it has nothing to do with getting a second serving of soup at Smorgy's! Resupination is the process by which the flowers of many orchids, as they open, twist so that the lip is orientated below the other floral segments. All of the commonly grown genera (Cymbidium, Dendrobium, Phalaenopsis etc.) have resupinate flowers. Twisting is due to rotation of both the ovary and pedicel.

    One of many interesting features of resupination is that the flowers only undergo resupination if it is necessary to orientate themselves so that their lips are lowermost. Thus the flowers on the ascending part of an arching inflorescence undergo resupination, while those on the descending part do not.

    Another curious feature is that, as a general rule, the direction of resupination alternates from flower to flower up the inflorescence. For example, if the first flower on the inflorescence twists in a clockwise direction during resupination, then the second one twists in an anti-clockwise direction and so on! Resupination begins to occur as the buds open and is essentially complete by the time the floral segments are fully expanded.

    Why are most orchid flowers resupinate? The main theory is that resupination orientates the lip to provide the orchid's pollinator with a convenient landing pad. This theory sounds reasonable, although the American glossy bee Euglossa cordata is known to pollinate the flowers of several different catasetum species whether their flowers are resupinate or not.

    Most resupinate orchid flowers twist through 180 degrees as they open but the flowers of Angraecum superbum rotate through 360 degrees, so that they eventually reach the same orientation as if they were non-resupinate! Orchids with non-resupinate flowers (their lips are uppermost) include Osmoglossum pulchellum, all species of the Australian terrestrial genus Prasophyllum and some Satyrium species.

    From an aesthetic viewpoint, resupination is important to orchid growers. Nothing looks more ridiculous than an arching cymbidium spike that has been staked upright after the flowers have opened. All the flowers face upwards, with their lips uppermost. By all means, stake such an inflorescence upright for transport but on arrival release the ties so that the flowers are displayed in their customary manner.
