Well, it's not a Calluna vulgaris http://dpipwe.tas.gov.au/Documents/Heather_CRC_wmg.pdf
Lilac Indulgence sounds lovely , but what sort of plant is it?
It must have a botanical name consisting of its Genus and species, then 'Lilac Indulgence' will be its varietal name.
e.g. Solanum lycopersicum is the tomato's botanical name, there are lots of varieties such as 'Gardener's Delight', Alicante', 'San Marzano'.
Without the full name we don't know what sort of plant it is
