    Dendrobium Aussie's Hi-Lo (cuthbertsonii x laevifolium 'Sam's Choice') is a hybrid I purchased from Tom Perlite about a year and a half ago. This particular clone is a nice bicolor form of the cross that has been relatively vigorous for me. While it could probably tolerate warmer conditions, I grow it alongside D. cuthbertsonii clones and other cool growing orchids. It benefits from quite bright LED lighting and high humidity throughout the day and night, maintained by automated fogging several times throughout the day. Good water quality is a must, as with any Oxyglossum group Dendrobium.

    Interesting that the bicolor came through. I wonder if there is a ploidy difference? cuth 4n X laevifolium 2n?

    In my experience, not necessarily. I've bloomed a batch of cuthbertsonii "Lafayette" (wild bicolor) x laevifolium, and approx. 50% came out as superb bicolors. Unless Lafayette is a chance wild polyploid, and it sure doesn't look like that, it seems the bicolour character can come even when paired 50/50 with purple laevifolium!

    I do not know the specific clone of D. cuthbertsonii that was used to make this cross, but I do know that the cross produced a batch with variable flower colors because I own three plants from the same flask (including this bicolor, a nice solid red, and a very deep red/magenta... photos of the rest will probably be forthcoming shortly). Tom Perlite may have more information about the parentage than what is listed on the label and I can see if he has kept records. I would really love to see a pink/white bi-color Aussie's Hi-Lo. I wonder if it might be easier to produce this using an alba form of D. laevifolium crossed with a strong pink/white D. cuthbertsonii bicolor (if the color background of laevifolium matters at all).

    Tom said that the parent cuthbertsonii was a high quality bicolor but it was pollen obtained from another grower and he did not know if there was enhanced ploidy or whether there was a clonal designation.

    There is something puzzling..; D. Aussie's Hi Lo is cuthbertsonii (pod) x laevifolium (pollen parent). And here you mention cuthbertsonii pollen? Does it mean the cross has been remade in reverse order, using cuthbertsonii as pollen donor?

    I got some AHL from Tom when he was reducing Golden Gate. Most are sunset tones, reds suffused with the almost neon purple of laevifolium.

    Pacome, I may have misinterpreted Tom's email regarding the details of the cross. I assumed that since it was his cross and his laevifolium that the pollen had come from the other grower's cuthbertsonii, but it's possible that it was the other way around and the other grower let him use the cuthbertsonii as a pod parent.

    Do you have photos posted on the forum of these clones? I'm curious to compare the color saturation.

    I used a couple purple and a couple reds to make a distinction in color. The flower in upper left is the hybrid.

    Very nice! I'm also envious of all the seedlings hiding in the back. ;)
