    Typically it is recommended to keep that species mounted. Looks like pot culture can be used as well with one note - repot only when it is absolutely necessary. Each repotting causes temporary decline of the plant.

    Dang, that is nice. Do the canes flower multiple years?

    I recently moved mine to a shadier and cooler spot to see if I could get it to flower. My plant is beautiful but has never bloomed.

    The first picture is great. Next time I see one at a show I'll be picking one up.

    Kelly,

    AOS Bulletin June 1992, Mark and Allison Web, "Australian Orchids": ...Flowering occurs from nodes along the length of the pseudobulbs. This occurs more frequently as pseudobulbs age and the apical nodes are depleted. ...It will flower poorly when kept too dry during the winter.

    I do not cut off lifless pseudobulbs unless they are obviously dead. Regarding second part of the Web's quote: perhaps that is why for me pot culture works well. On mount plant would be too dry.

    Beautifully grown, Alexey! Does it have a varietal label?

    Label has only clonal name, not varietal. Now one can only speculate if that is pure i.e. Den tetragonum var. tetragonum or it has more complicated set of ancestors.
