Product information

Are you searching for that perfect evergreen foundation plant that brings a splash of rich colour to the late spring garden? The Rhododendron ‘Catawbiense Grandiflorum’ offers a truly spectacular display of showy lilac-purple flowers, ensuring your border remains interesting long after spring bulbs have faded.

This popular rhododendron maintains its beautiful glossy, dark green foliage throughout the year, providing excellent evergreen structure; its growth habit is naturally bushy and rounded, offering good cover and wildlife value, as its blooms attract beneficial pollinators like bees and butterflies. While it does produce small dry seed capsules, they are rarely a prominent feature in UK gardens, keeping the focus firmly on the stunning floral display during May and June.

To achieve the best results for this plant, ensure it is positioned in your garden where it benefits from partial or dappled shade, thriving best in humus-rich, acidic soil that remains consistently moist but well drained. This specimen excels planted within informal shrub borders or woodland settings, offering welcome screening, so consider its placement carefully to avoid harsh, exposed locations to protect it from damaging winds.
