Diane, what are ya talkin' about?

Now you spoil it, I have to spill it out!

The Kings of the Orchids are Dendrobium speciosum var. hillii and other members of this alliance including var. speciosum and var. grandiflorum. One of the prime members of these orchids is the Den. speciosum var. hillii 'Don Brown' which received a 99 points CCM/AOS, the highest ever score given by the AOS. When it was exhibited, the gargantuan plant had ~400 spikes with >100,000 flowers! It weighted several tons and formed a ball of at least 8 feet in diameter. Another clone called 'El Queso Grande' received a 98 points CCM/AOS. This one when exhibited formed a ball of almost 10 feet in diameter with 230 spikes and >35,000 flowers!
While you are still in Australia, ask Tim-O to see whether you can take a few of these beauties home to the US. (They might let to do it if you ship them bare-rooted.) A decent size plant of these guys could easily fetch a few thousand dollars here in the US! The climate in Southern Cal is perfect for them! They will grow just like weeds in your patio or backyard! And they are very tolerant of neglect and overzealous care! Easy to grow (maybe not that easy, you got that California weather working for you!) but even tougher to kill! A perfect fit for you, a globe-hoping traveler!

Cheers. Hoa.
