Dahlia ‘Moonfire’
We were at a BBQ in Healesville recently
and I saw these Dahlias in the garden
The dark foliage and the yellow coloured blooms made them really stand out 
My friend said they were one of the easiest plants to grow
she had in the garden
Never lifts them, just trims them back in autumn
and up they come again
at the beginning of each year (our spring/summer)
Don’t they look nice and bright and summery
Made me think about asking her for some pieces lol   
Some of these links are for Australia
some for the Northern Hemisphere
