Thanks for the suggestions.
lol I have American blackberries in the backyard. I think they might get terminal roundup next year. V.tough and great fruiting but they are taking over and oooogly.
Geoff, not sure what you've got against poor old Dandelions

I tried bluey with a few E.maculata flowers to no avail - I might have just got him on a bad hair day. I was thinking maybe Pigface (native Carpobrotus sp?) I have several Dianella species, I'll divy some up and chuck them in the spaces. Do you know if the berries on Lomadra longifolia are edible? I have Walenbergias, Calotis (burr daisy), Brachyscome basaltica and multifida - I just had trouble imagining how they could result in a food source. My Kunzeas all got fried from -6C frost last year - all but parviflora is a dead loss here. I have some cuttings of a scrambling form of E.glabra I'll try that.
Richard - I like the Tomato idea, I might chuck in some cherry tomatoes, or Romas and See what happens. Strawbs would be good but realistically probably too hot and dry to keep them alive through summer.
Lisa and Leigh yeh these ones are true dandelions, lots of cats ears and other stuff than look like dandelions around - I'll try a Hamilton tree planter and try and core them out to transplant. I thought Dandelion cos they could pick off the leaves/flowers at will in the enclosure.
