There are a lot already mentioned I want to second but won’t with all of them to save space. B. cucullata has to get an extra round of applause from me though for having been in bud or flower for years, also B. grandiflora for the first fourth to a third of the year reliably (powdery citrus on that one)…B. nodosa and I are at odds because I can’t get it to bloom, leaving me feeling like the village idiot (My husband has caught me tough-talking it).
Other favorites are Meiracyllium wendlandii, which blooms reliably with a nice display of magenta, cinnamon-scented flowers every November, Epi. nocturnum, which blooms throughout most of the year, Epi. magnoliae… Did anyone mention Paph. delenatii or Phrag. schlimii? That last one passed on the rose scent to my Phrag. Elizabeth Castle which I enjoy all the more for it. There are many more of course. You can hardly go wrong with any of the angraecoids—Aerangis fastuosa and Angraecum didieri are my favorites among those so far, but I have yet to sniff the Angraecum florulentum which I’ve read in multiple places is “best of the genus” for fragrance. Masd. strobelii, Masd. glandulosa, the hybrid of the two Masd. Confetti, Masd. Celtic Frost… Den. moniliforme is really nice too.
