To all of us who love terrestrial orchids, 2015 has been a very disappointing and dispiriting year.

Yes, on the odd occasion we have been able to admire the beauty of some of our species, but on the whole, the plants have been short lived and the flowers have been very weak.

The sun orchids, that usually enthral us in the spring, were just a non-event caused by the lack of autumn rains that are needed to stimulate the orchid tubers to awaken and send up strong shoots. The dry spring and the burst of very hot weather in early October were disastrous for those plants that had managed to put up flowering stalks. They just withered and collapsed as we observed them in the field. A few managed to open but you had to be lucky to see them.

Some Flying Duck Orchids Caleana major are presently flowering, but again they are small and not very strong. You can, however, still be fascinated by these unusual flowers that give the appearance of ducks in flight.

It could be as a result of some winter rainfall that we are now starting to see Rosy Hyacinth orchids, Dipodium roseum, growing throughout the district in quite large numbers. At the present time we are just seeing dark reddish-brown flower stems appearing in amongst the dry vegetation, often clustered around the bases of trees, where their associated mycorrhizal fungi thrive in the extra bark and leaf litter.

If you look closely at the top of the stems you will see the flower buds just starting to form with a tight cluster of flowers.

Hopefully we will get enough moisture to encourage these buds to swell and open into the beautiful pink flowers that we usually see scattered throughout the bushland during the summer months.

Orchid watching is a complex game, but despite the struggles, we continue to play, optimistic that the underground tubers are surviving and that next year we will once again be enthralled by the beauty of these majestic flowers.

Weed of the month

Freesia

Freesia

Freesia refracta and Freesia alba X F. leichtlinii are declared weeds in the Surf Coast Shire because they spread easily and threaten to invade bushland. Freesias are perennial herbs that die back in summer and produce new foliage in winter. The highly fragrant trumpet-shaped flowers appearing in spring are white to cream and pink with yellow markings, shaded purple on outer surface. Each plant has at least two corms, one below the other, thus requiring deep digging to remove them.

More details about how to control this weed can be found in the archive of Weeds of the Month.
