Lovely.. you knew what orchid I had... the flowers were awhile ago.. and I was thinking I couldn't remember what they were like... well... the plumeria gets a strond blast of east/ southeast light from the window... and it is at the edge and about 4 ft away from a 15 hour day 400 watt metal halide... just switched off from my HPS light a few monts ago... but the biggest spur to plumeria is bottom heat... they sit on a slab of 1" thick glass... that spans the top of two radiators that fit in a corner... so they get strong bottom heat... Mine have always done well... as I grow thhem on a hot roof in the summer... the membraine gets to be 165* F when the air temps get to be say 85*F...when folks ask how to spur theirs on I recomend moving them to the top of the driveway...they adore hot roots...IMHO... as it is from personal observation in a number of garden and wild situations... the light and food always plays a big part in success.. they are also loving being near my humidifier... the fog has increased the leaf size... also it was getting rid of the spyder mites... the poor plant likely has all the nourishment it was giving to them left over now... so flowers...
