Description
Like flames dancing through an enchanted woodland, Pieris ‘Mountain Fire’ ignites the Irish garden with its spectacular display of fiery red new growth that seems to glow with inner light. This magnificent evergreen shrub offers a year-round spectacle that changes with the seasons, beginning each spring with brilliant scarlet shoots that gradually mature to lustrous dark green, creating a living tapestry of colour and texture.
In early spring, just as our Irish gardens begin to stir from winter’s slumber, ‘Mountain Fire’ adorns itself with cascading clusters of delicate, bell-shaped flowers in pristine white tinged with the softest blush of pink. These fragrant blooms dangle like tiny lanterns amongst the emerging crimson foliage, creating a breathtaking contrast that heralds the arrival of the growing season.
This aristocratic shrub thrives in Ireland’s naturally acidic soils and appreciates our gentle, moisture-laden climate. The dramatic colour transformation of its foliage – from blazing red through bronze to deep emerald – provides months of visual interest, making it a cornerstone plant for woodland gardens, shrubberies, or as a stunning specimen in containers.
Perfect companions include acid-loving plants such as Rhododendrons, Camellias, and Heathers, whilst the silvery fronds of ferns and the delicate flowers of Hellebores create beautiful underplantings. ‘Mountain Fire’ is particularly striking when positioned where morning light can illuminate its fiery new growth, transforming any corner of your Irish garden into a scene of natural drama and beauty.
Caragh Garden Notebook
Plant in autumn or early spring in acidic, humus-rich soil with excellent drainage. Choose a sheltered position in partial shade, protected from strong winds and harsh morning sun which can scorch the tender new growth. Ideal for woodland gardens or alongside other ericaceous plants.
Water regularly during dry spells, maintaining consistent soil moisture without waterlogging. Apply ericaceous fertiliser in spring and mulch annually with leaf mould or composted bark to maintain soil acidity and moisture retention. Container plants require ericaceous compost and regular feeding during the growing season.
Prune lightly after flowering if needed, removing any dead or damaged wood. Avoid heavy pruning as this can reduce flowering.
