Lobethal roadside scrub verge – October 25th, 2014 – warm, dry conditions

Photos & Text: Michal Dutkiewicz

These were growing next to a roadside metal rail in, what at first sight, seemed to be very unpromising conditions. We had stopped the car to take photographs of an old brickworks that was just 50 yards or so down the scrub-covered hill from the road – I was stunned to see these amazing Orchids in quite a dense group. I didn’t know what species this was, because the blue Thelymitras confuse me, but Sheridan Ford said, on the Australian Native Orchids Facebook Page: “My guess is T. bracteata. I don’t think it is pauciflora as pauci only has 1-5 flowers. The giveaway for me is the large, prominent bracts, sharply bent column arms with toothbrush-like hair tufts and the robust habit of the plant.” Thanks Sheridan. Here are my other articles on Thelymitra plus some outside links you may find useful:

Mount George Conservation Park (Deanery Hill), South Australia – October 18th, 2014 – warm conditions after previous day’s rain

This is not a common species, but it is pretty spectacular! One source in The South Australian Naturalist, November, 1919, described it as “The most robust member of the genus”, and in The Gardener’s Chronicle, April 15th, 1882 this species was described as “…the largest and most beautiful Thelymitra known”. Flowers about 3cm wide heavily clustered up a tall stem 35-75cm high. Among the many similar plain blue species, this is possibly the least difficult to identify because of its size and the lemony colouration of its central sex parts. Like all Sun orchids, this species needs warm weather over 25 degrees C to open the flowers. It blooms from October to December.

These are my favourite Sun Orchids – The blues, mauves, sea greens and dash of yellow make it a harmonious pictorial delight – They did not evolve to please the human eye, but whatever lucky creature they attract, I am glad we get to share them.
