Acquired from Hilo Orchid Farm in 2019 as a 5-flowered first bloomer. Blooming this year with 4, but not bad for a windowsill-grown plant! Cross is ‘Red screw’ x ‘Long life’. Petals are currently 21 cm, and maybe still growing a bit. I’ll update once all are open, but I had it out to water so I snapped some quick pictures.
