It's in a neglected bed of Lily of the Valley that has coneflowers, milkweed, goldenrod and probably other native plants that have snuck in or been planted very haphazardly. I plan to keep spraying the LOV with Round Up until it stops returning, and encourage all the natives to increase. I don't know if I should try to make it look organized or not. Time wise, I vote not. I'll keep adding shade tolerant natives and see what survives. Thanks for helping. Maybe I need to leave it another year and see what it does. Martha

Hardenbergia certainly wont and I don't think the Pandorea will either, though I've not planted that, it might need keeping an eye on. As you're in Melbourne I'd try a few Clematis: Aristata (old man's beard) and C. Glycinoides are Aussie natives. Neither produce flowers as dramatic as the non-native varieties but worth a place in the garden. Clematis do need special treatment however, but are certainly not difficult and there are many sites covering their varieties and cultivation. By the way, I posted a pic. of one a few weeks ago in the 'Gallery' page (next one below this page, I think).

Oh my gosh! You got it! Thank you!!! It used to be called baccharis emoryi (here in Zion) , and it got reclassified as baccharis salicina. What threw me off when I looked at your link were the toothed, and wider leaves. But when I typed in baccharis with zion national park, this is what I got! zion/white_wildflowers/baccharis_emoryi_i93.html That's it to a "T"! Tiny flowers with no discernable petals, and elongated, more lanceolate leaves! I can't thank you guys enough! Apparently it's one of the riparian plants here. It must have mistaken my gutter drainage for a wash LOL! Woo hoo!

That looks about right - thank you!
