A lemon tree. An orange tree A bird of paradise A splash of yellow on this otherwise grey plant. Another angle, showing the neat leaves. Cacti, a type of aloe(?) A hibiscus, correctly identified from afar by Jenn. The little guy is having a good time Lunge! Graeme dips into the cheerios for sustinance As we depart, the Douglases pose by the Douglas Fir. (Graeme's middle name is Douglas, for those who didn't know.)
