I have recently been obsessing over (reading about, buying, planting...) Penstemons of all varieties, Cosmos atrosanguineus (Chocolate cosmos), Nepeta spp., Salvia spp (including, but not limited to, Salvia leucantha, Salvia nemerosa, and Salvia discolor), Agastache spp, Perovskia atriplicifolia (Russian Sage). I seem to be creating a perfect hummingbird-attracting backyard; shame we live on the wrong continent. Let's hope honeyeaters will enjoy these plants just as much.
Pictured below are just a few of my newest acquisitions. I might have bought out most of Adelaide of the supply of smaller (read: cheaper) Chocolate Cosmos...
Edit: forgive the strange bold/not-bolded text. Sometimes technology will not cooperate with me.
