Australian Native Wildflower as Garden Specimen

 

Comment

Eremophila flaccida subsp. attenuata is known from one small area south-east of Gascoyne Junction in Western Australia where it grows on stony rises. This subspecies is recognised by its long strap-like leaves. It is extremely difficult to propagate from cuttings and is commonly grown, as is this specimen, grafted onto Myoporum species.

Another set taken on 23 November 2014, including UVIVFL. It is interesting to compare the appearance of the pollen on the anthers and also smeared on the petal above. In Visible light it appears cream, (Anther: R 241, G 225, B 192, on petal: R241, G 230, B 208) in UV it appears blue, (Anther: R 138, G 137, B 181, on petal R 142, G 145, B 180) and in UVIVFL it appears fluorescent blue, (Anther R 42, G 156, B 255, on petal R 97, G 180, B 255).
