Den. lindley
 

Den. aggravatum blooming for me for the first time. Last year I did everything you're suppose to do for them to bloom.... It didn't bloom. This year I shoved it in a corner with the Nobile Dendrobiums and bam...
Strange the inflorescences are not pendent.

Very nice! I guess it was the cool rest with the nobile's that did it. OW says it needs a cool rest to bloom. Not sure what you did differently last year.

Oh what a beauty. I thought these were warm growing. I need this one if it doesn't mind being cooler sometimes.

Lovely!

No-Pro-mwa, check out Dendrobium section Densiflorum on IOSPE. They are deciduous plants that like warm, wet summers followed by cool but not freezing, sunny winters with less watering.

A lot of stuff you read in books and online says they need a dry winter rest, but that doesn't take into account most of them get a lot of dew in the winter. There are a lot of threads on Dendrobium aggregatum on this board (which is a synonym for D. lindleyi.)

When I read on IOSPE I was a little surprised there were described two sections of Dendrobium with groups of yellow flowers. I went poking around and found a paper that used DNA analysis to look at Dendrobium. The relationships of species in Dendrobium, and the division into sections, is undergoing revision. D. jenkinsii and D. lindleyi (synonym aggregatum) are closely related to each other.
