means A container of trailing plants suspended at eye- or head-height, usually from a hook, bracket, or porch beam.

from Straightforward compound — 'hanging' plus 'basket' — rather than a word with a secret past. Baskets themselves are ancient, woven from reeds and willow long before anyone wrote the word down; 'basket' likely traces back to Latin or Celtic roots, though its exact origin is debated. The 'hanging' part is just English doing what it does, describing the thing by what it does: it hangs. The practice of suspending planted baskets for display became especially popular in gardening culture from the 19th century onward, as wirework and ironmongery made it easy to dangle greenery from porches and shop fronts.
