Highlights of the spring blooms at Trengwainton Garden

Rhododendron loderi in bloom

Throughout May and June, the garden at Trengwainton reaches a crescendo of colour from the rhododendrons, azaleas and stream border.


Trengwainton has a very special collection of rhododendrons that were largely grown from seed gathered by the great plant hunter Frank Kingdon-Ward on his 1927-8 expedition to north-east Assam and upper Burma, or from hybrids that are unique to this garden. 

Now very mature trees, they’ve reached a towering height and have shades that pass through virtually the whole colour spectrum; from fragrant whites and pinks, to soft yellows, oranges and deep, rich reds.


Large azalea bushes can be seen in the walled garden, on the Drive and in the Azalea Garden that’s situated behind the pond at the top of the garden. 

They have lively names such as, Sunbeam, Firefly and Bridesmaid and some have colours that are so vibrant they border on the fluorescent.

The stream border

A feast of colour in the spring and summer, the stream border is a favourite spot for moisture loving plants such candelabra primulas, crocosmia, astilbes and arum lilies. 

The arum lilies include an unusual green coloured one that goes by the name of ‘Green Goddess.’


The romantic poets of the 19th century, such as Keats and Tennyson, believed that bluebells symbolised solitude and regret. These days, it’s hard to imagine a more uplifting sight than a carpet of bluebells bathed in the light of the warm May sunshine.

The winding, wooded paths at Trengwainton mean there are lots of opportunities to see the bluebells growing in the dappled sunlight beneath the trees.
