Dendrobium williamsonii

[Regelian]

Very similar to D. cariniferum, but the lips is finer and the keels on the sepal backsides are less wing-like. Fine fragrance of oranges, even in the night, which could mean moth pollination in the wilds. Flowers about 3cm across, slightly hanging and carried single (in this young plant).

The closely related D. schrautii has non-resupinate flowers, appearing upside down, lip upper most.

Lovely. I got a plant in last spring but it could not survive our hot summer.

Can anyone give me care tips on den. Williamsonii? Such as light and winter rest requirements etc.? Thank you in advance

[Regelian]

I give mine as much sun as possible in the Winter (SE window) and half shade in Summer. Likes water, but should not be kept constantly wet, just moist. More an intermediate grower than warm, so be carefull not to let the canes get too hot. They may rot. Mine blooms in the Spring after a cooler period and somewhat dryer rest, but never completely dry. Most of the Section Formosae come from rather wet areas and are often found growing on mossy branches. Good air movement is always positive. Actually a pretty easy charge. Hope this helps.

Hi Regelian, thanks again for the info! I have just acquired a d. Williamsonii and trying to learn more about it. Hope mine will bloom soon!
