Hosta 'Blue Mammoth' is a stunning, large-growing hosta prized for its impressive, heavily corrugated blue-green foliage. A sport of the popular Hosta 'Blue Angel', this variety produces thick, heart-shaped leaves that form a bold, architectural mound, making it a striking focal point in any shaded border or woodland garden. The substantial leaf thickness provides excellent natural resistance to slug and snail damage.

In summer, tall stems emerge bearing clusters of pale lavender to near-white, bell-shaped flowers that attract pollinators to the garden. As one of the larger hosta varieties available, Blue Mammoth delivers real impact when planted in shaded beds, beneath trees, alongside water features or in large containers.

Each plant is supplied as a well-established 17cm/2 litre root ball, ready to plant directly into your garden or a suitable container.

• Enrich the planting area with organic matter such as compost or well-rotted manure.


• Water regularly during dry spells, particularly during the first growing season.


• Apply a mulch around the base in spring to retain moisture and suppress weeds.


• Divide established clumps in spring or autumn to maintain vigour or create new plants.
