rose moss
LowSpecialised/Gardening
Definition
Meaning
A low-growing, succulent annual plant (Portulaca grandiflora) with fleshy leaves and brightly coloured, rose-like flowers that open in full sun.
Often used as a vibrant, drought-tolerant ground cover in gardens, rockeries, or containers due to its spreading habit and colourful, persistent blooms.
Linguistics
Semantic Notes
The name is a compound noun that combines the appearance of the flower ('rose') with a common name for moss or moss-like plants ('moss'), though it is not a true moss. It is also commonly known as 'portulaca' or 'sun plant'.
