Subterranean Clover

Better than Sudokus

Last week I was invited to participate in a weeding session at the Murchison Spur lookout. The Strath Creek Landcare Group had previously planted the area with native flora and in preparation for the upcoming weeding/clean up event on November 30 (hint, hint for those who have a couple of hours free) it was decided to prepare a model (weeded) area to highlight to the many eager weeders who undoubtedly will turn up, what is a native plant and what isn’t. Sometimes it’s difficult to tell.

DSCN4282How hard could it be? Well very hard actually. Forgetting about the occasional rain shower and the gale force winds I was assigned an area consisting primarily of ground creepers (pictured left). Intertwined on the ground were Running Postman (Kennedia prostrata) and Subterranean Clover (Trifolium subterraneum).

DSCN4289Separated, it is easy to distinguish between them. The former has red pea-shaped flowers (pictured right) and the latter white flowers. But mixed together they formed a puzzle more complex than the most devious Sudoku. DSCN4285The trick is that the leaves of each have a slightly different shape and the clover leaf has a light pattern on it (see left). It took hours to carefully separate the two and remove the clover.

So if the cryptic crosswords are getting too easy and the sudokus a breeze, November 30, 10am, Murchison Spur Lookout. If you really want a challenge.
