Australian Native Wildflower as Garden Specimen

We had been looking for E. mackinlayi ever since the post of a photograph of a specimen growing in Death Valley http://www.ultraviol...i-desert-pride/ but is not common in plant nurseries which we visited. The flowers on this specimen may be a little old leading to the petal tips being bent back rather than pointed as in the earlier photograph of the US specimen.

There it is!! My first Eremophila -- which took me months to identify because I saw this Australian native growing "out of place" in California.

:D

 

Thank you Dave for posting this. And to Sue for finding it.

 

I also found this reference in an Australian flora: https://florabase.dpaw.wa.gov.au/browse/profile/7235

One of the many (?) problems with Eremophila ID is that they occur in many Australian States and the link is only for Western Australia. In fact, the distribution map actually corresponds to both subspecies when you compare it to the maps in Chinnock. The scatter on the west coast is subspecies mackinlayi and the ones further inland are the ones which Chinnock found for subsp. spathulata, described in 1990. I often have this problem when I look at the label on a bought plant and then go to Chinnock to find that the label only describes the nominate species. The third and most recent reference gives this subsp the name Desert Pride as you found it was known in the US, but not in either of the earlier references.

 

Chinnock puts E. mackinlayi in section Hygrophanae which also contains E. hygrophana and E. strongylophylla to which it is closely allied and all three overlap in distribution - so identifying a specimen in the wild is not all that simple!
