Heath (dutch: heide) is an evergreen scrub or tree of the genus Erica (family Ericaceae).
Heath often grows together with heather (genus Calluna Vulgaris; family Ericaceae) on acid soils throughout Europe. Both plants have purple-colored flowers. Dwarf species, such as
bog heather and bell heather, are abundant on acid peaty soils, such as moorlands. Land covered with these plants is also often called heath.
The name "van der Heijde" means from the "heide" or heath. And because I am a hydrologist by training, I called my company Heath Hydrology.
