Cymbidium Dayanum Positive ID? - Orchid Board

Kevin_PR · #1 10-03-2013, 02:49 PM

I have a NOID cymbidium that I think I have narrowed it down to Cymbidium dayanum. Can anyone confirm. It is a warm growing cymbidium with a pendant raceme. I grow it in a pot but When I divide it I may try it as an epiphyte. It is a large plant but has only bloomed once in my care.

Hmm ... maybe ...

The blooms look quite like dayanum. Comparing the growth of yours to mine, I'm not sure

According to IOSPE - these usually get 5-12 buds/blooms per spike ...

Posting photos of mine - blooms and growth ...

Hopefully someone more knowledgeable than myself can be more definitive.

I had my dayanum four years before it bloomed for the first time last fall - it has spikes right now. The difference, I believe, in my case was letting the media become nearly dry before watering.

Hi,

Yours look more like aloifolium. Aloifolium has thick strap-like leaves while dayanum has more grass-like leaves.

Dayanum blooms have a more spikey pointed look, while aloifolium has softer rounder edges.

Kevin, can't help with identification, but so glad this thread is here, I was looking long time for warm growing cymbidiums and this one is stunning. I did find seller on eBay selling division of Aloifolium, he is in Florida as well, so I know it will grow great! I must figure the potting mix for it and hope I will get my plant bloom some day like yours! Love this color. How do you grow yours?

The flowers on both species look similar but I see what your talking about with the foliage. My leaves look much thicker than Whiterabbit's and the pbulbs look larger too. I might have both species, I have another NOId Cym that has the leaves at half the length of the plant pictured and the p bulbs are much smaller. So I will label the plant as aloifolium for now.. Thanks guys.
BTW if its dayanum it does not need a rest if its aloifolium it does need a rest, so I'd say the thick strap like leaves and the larger p bulbs suggest drought tolerance and would make more sense for aloifolium. Anyone think it could possibly be a hybrid? The lines on my blooms are not as bold as other Photos I have seen of either species. I'm hoping its a species.

Definitely NOT dayanum. Your plant is in the coriaceous leaved, warm growing group, those with fleshy leaves. There is similarity in the related species, finlaysonianum, atropurpureum and aliofolium and color variety within each species. Some may have more distinctive lines than others. Bicolor is also a member of this group too.

The best advice for growing is to "hang high and bright" in a greenhouse. I have never withheld water but it all depends on temps and amount of light. I do not withhold water from my dayanums either and get specimen blooms every year without fail. They grow more like weeds than any other Cym I have in my collectionl
