Dendrobium anosmum var huttonii

    A lovely variant of Dendrobium anosmum. This particular plant bloomed twice this year from different parts of the same cane. It bloomed in March, the usual anosmum blooming season locally and again in April. Unusually the April blooming was better than the March one. This clone, which I don't know if it has ever being awarded, has an excelent definition between the white and the purple. I have seen plants that are very pale forms of the normal form being sold as var. huttonii. It may be that its tendency not to bloom the full lenght of the cane, but from discrete sections may have prevented if from gathering an award.

    I really like the crisp delineation between the colors on this one.

    Sigh: cannot have possibility to accommodate this group of Dendroums in my setup!

    Ricardo, how long do the canes get on this variety?

    @Kelly, most of the canes stop growing when they reach a lenght of four to four and a half feet. But sometimes canes grow larger, one of the canes is five feet, five inches long. I am sure this plant has the potential to produce canes more than six feet long. However to get the canes this six feet I would have to give this plant a more meticulous degree of care than I am giving it right now. By the way, this plant is growing on a wire cloth pot four inches deep and four and a half inches across.
    @Alexey, if size is an obstacle to keeping this species, there are smaller representatives of this group that are as powerfully frgrant as the larger representatives, Dendrobium parishii comes to mind.

    Ricardo, my Den parish still has manageable size, but last year canes are more than 12”, which is bigger than what I have seen on some photos. Would high light, low temperatures and rather dry growing period do the trick, or “dwarfism” is genetic and not dictated by culture?

    You have noted something that seems to be paradoxical of parishii. Plants cultured in the coast seem to be much smaller than those cultivated in the highlands. So there may be a climatic/temperature effect at play there. Also I have seen several types of clones from the really tiny, an alba form, to clones that are three or more feet long. So apparently cultural conditions play an important part but genetics is also a factor. My guess is that by giving it low temperatures you are actually giving this plant its preferred temperature range and this stimulates good growth even if you don't water it as abundatly as it would like. High light, at least with anosmum, can stimulate the plants to reach heroic sizes, if coupled with good fertilization and abundant watering.
