Beyond the biggest Queen Elkhorn : Platycerium wandae and another solitaly species such as P.superbum and P.grande, this Holttum's staghorn is also a giant staghorn in the tropical world.

There are 4 species of staghorn native to my tropical country, Thailand. They are P.coronarium, P.ridleyi, P.wallichii and this P.holttumii.

P.coronarium and P.holttumii seem to grow more easy than another two. The plant in the picture is about 7 years old with 2.5 feet of upright crown fronds and 3.5 feet of pendant fertile fronds. I mount the plant on a column of my lath house because I can't hang it like other small epiphytes. It receive a half day 50% sunlight from the morning and 2-3 times per week watering with a high potassium (K) fertilizer once a month.
