Hobart’s heat wave has been broken with a suitable amount of rain. Expect your gardens and weeds to double in size this week. The opening Epiphyllum Cacti, and the now chilly weather have prompted this post. It stands to reason that can’t mention the Epiphyllum (or Orchid Cactus) without mentioning orchids. This time of year, Masdevallia and Sarcochilus rule the roost in Hobart. Here are some of the current contenders. The Hoya (Wax Flower) in the glass house is also putting on a great display, although, not an orchid, or even a cacti posing as one, it is worth admiring.
