Serious alien species weed, gone to seed.
Weed regeneration post autumn 2016 [to check date?] ecological burn.
High sand dune, west aspect top slope;
sand heathland, this slope patch slightly retains moist sand, seasonally, throughout the history I have noticed over 30 years, thus not quite dry,
rather slightly moist to summer dry, sand heath;
Unlike the nearby ca. 9 months of the year much drier, dune top, 3rd E way dry sand heath hence with some different and special species.
