Australian Native Wildflower as Garden Specimen

 

Comment

This hybrid eremophila is a large spreading shrub which is excellent for screening and is fast growing. It flowers prolifically in summer and is drought and frost tolerant.

This Eremophila seems to be visibly enticing rather than UV attractive.

 

I've come to love the Eremophilas after my grand adventure through the Eremophila key for the identification of my Death Valley specimen. Someday I'll have to make an Australian field trip to see some of your amazing wildflowers. Have you been to any of the botanical gardens to photograph yet? They are delightful sources for UV fotos. I'm already planning some spring trips to some US gardens.

The best botanical garden for Australian native flowers is in Melbourne, we haven't been back there for a couple of years. We are past the Springtime flush of flowers, they know to hunker down for the Summer.

 

I will put together, for the Reference section, some notes from Chinnock about insect pollinated vs bird pollinated Eremophila. It seems from a quick scan that E bignoniiflora which is one of the parents of this hybrid is bird pollinated and did not show "nectar guides" in UV in the way that insect pollinated ones did. Most of the eremophila I have posted so far have been insect pollinated ones. I don't think this hybrid really cares as I have certainly seen native bees around it.

 

I have just found the following reference which says most of what Chinnock has to say: www.asgap.org.au/APOL24/dec01-3.html

Unfortunately the UV reference in it is to film.
