In the centre picture I've wrapped an elkhorn around an 80mm.dia piece of paperbark log and growing epiphyticaly on the top is Hoya serpens and Hoya curtisii.
In the bottom photo on the very top of the elkhorn is Hoya odorata, an upright growing plant more of a shrub than a climber on the left is Hoya obscura which should cascade down from its pocket nicely. In the centre is a small cutting of Hoya lacunosa and a hoya multiflora which I thought I'd lost but is starting to sprout again since I planted it in the elkhorn. Being mostly epiphytes Hoyas don't need a lot of medium thats why it's good to grow some this way. Hopefully I'll post these pics again down the track after we've had some more growth.
