Welcome to the ninth part of my Madagascar BiOrbAir Terrarium Trial – growing epiphytic orchids, which are endemic to Madagascar, inside the BiOrbAir terrarium.  This Madagascar BiOrbAir Terrarium was set up in April 2017, so as I write to you now, in April 2018, this terrarium was created exactly a year ago.  In this update I am delighted to share with you the distinct lime green coloured flowers of Aeranthes arachnites, which I find simply mesmerising!
