Hardenbergia Sea of Purple 180MM

Hardenbergia violacea 'Sea of Purple'

I am Hardenbergia Sea of Purple. My family originated from eastern Australia.

Habit Groundcover - Colourful Groundcover

Plant family Fabaceae

I am a fast growing native ground cover with a dense habit, spectacularly smothered in dark purple flowers from late winter until early spring. Other forms of Native Sarsaparilla are typically climbers or even an upright bush but ‘Sea of Purple’ is naturally a spreading ground cover well suited to trailing over retaining walls and from hanging baskets. I am hardy and adaptable but for best results plant me in a full sun or part shade position. I perform well in most soils but am happiest in light clays and free draining soils. My clusters or small pea like flowers are a magnet for butterflies, native bees and other beneficial insects. Being a member of the pea family I improve the soil by fixing nitrogen benefiting other plants.

I am popular and will make you happy because...

I produce a prolific display of deep purple flowers from early winter through spring

I am a cascading groundcover ideal for flowing over retaining walls, in borders, rockeries & hanging baskets

My flowers are a magnet for butterflies, native bees & other beneficial insects.
