Eens @emvee; typisch grassland.
Heath vertaald op wikipedia direct naar Heide in het Nederlands; dus snap die ergens wel.
Nu ben ik geen botanicus, maar als je op Wikipedia verder klikt naar de taxonomie wordt het verder zo omschreven (overigens vaak weer op de NL wiki naar Heide of Heester):
The Ericaceae (/ˌɛrɪˈkeɪsi.aɪ, -iː/) are a family of flowering plants, commonly known as the heath or heather family , found most commonly in acidic and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera,[2] making it the 14th most species-rich family of flowering plants.[3] The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (Erica , Cassiope , Daboecia , and Calluna for example).[4]
Nu zou ik een Rhodo eerder classificeren als een Heester (=Shrub) en niet als Heath; maar dat is mijn persoonlijke mening 
Maar als je in de diverse genera kijkt worden deze ook meestal omschreven als een Shrub:
- Plants in the genus Epacris are shrubs
- Plants in the genus Leucopogon range from prostrate shrubs to small trees
- Cassiope is a genus of 9-12 small shrubby species in the family Ericaceae.
- Daboecia /dæˈbiːʃiə/,[1] or St. Dabeoc’s heath , is a small genus of flowering plants in the family Ericaceae, containing two evergreen shrubs, closely related to the genus Erica . They are native to cliffs and heathland in southern Atlantic Europe and the Azores.
- Erica is a genus of roughly 857 species of flowering plants in the family Ericaceae.[3] The English common names heath and heather are shared by some closely related genera of similar appearance.
- Plants of Phyllodoce are subshrubs that occur in arctic-alpine regions.
