Not to be confused with :
Shore Dock (Rumex rupestris) [whose name also implies a connection with the sea, but un-like Golden Dock, Shore Dock grows only near the sea].
Hybridises with :
Broad-leaved Dock (Rumex obtusifolius) to produce Rumex × callianthemus
- Curled Dock (Rumex crispus) to produce Rumex × fallacinus
Marsh Dock (Rumex palustris) to produce Rumex × henrardii
- Clustered Dock (Rumex conglomeratus) to produce Rumex × knafii
No relation to : Golden Samphire,
Golden Saxifrage or Golden Alison, [plants with similar names].
Although the scientific name includes the maritimus moniker, Golden Dock does not only grow near the sea (mostly on the Norfolk and Suffolk coasts) but also well inland as far as the Midlands. Apart from
Marsh Dock (with which it hybridises), the flowers are grouped in whorls that are much more clustered than other Docks. And, of course, this is the only dock to turn a golden yellow when the fruits are ripe. The fruits are well toothed and possess three large and oblong warts.
It grows in dampish places such as stream-sides and reservoirs which dry out in summer months and is moderately rare.
