    Dendrobium subuliferum cross I purchased from Darrin Norton a while back and which is grown alongside other Oxyglossum group Dendrobiums under LED lights in my basement grow area. The leaves have a little red/orange tinge most likely because of the high light levels that the D. cuthbertsonii like (probably higher than ideal for this species). The plant blooms off and on throughout the year. It is grown in NZ sphagnum and kept moist pretty much all the time with light watering 5-7 days a week. Baseline water has a total dissolved solid count around 30-35 ppm and I keep it around 150ppm when fertilizing 2-3 times a month. Temps range from 62F nights to 78 F during the summer months and nights drop to mid 50s for several months in the winter.

    Beautiful specimen and wonderful flowers. Marni has done some outcrosses of this species and has some great clones.

    I purchased a flask from Marni a while back and the seedlings are in compots for now while coming up to size. The most vigorous of them are just starting to send buds, so I'll be curious to compare flower quality with the clones I got from Darrin.

    That is a nice specimen plant! Amazing. The violet color is so beautiful.

    I love this species! Well done sir.

    I have some of Marni's treated seedlings. I haven't noticed an easily observable difference to try and disseminate which might be polyploids.

    Upon getting some confirmed 4N, breeding for color would be a great venture! Not sure about the environmental pressures that might influence color.

    The two blooming size clones I have vary slightly in anther cap color. The one pictured is more blue and the other has more of a purple color. The flask I purchased was 2N, so I don't expect anything too unusual in terms of color. I'm curious to see what the 4N flowers look like.
