Allium Extravaganza

May 2026

Allium Extravaganza

The annual Allium Extravaganza started in late April this year and the final week sees the later varieties take centre stage.

Alliums are so versatile as they come in many different heights, shapes and shades of purple and white, the tallest can reach as high as 5 feet! Alliums are part of the same family as onions, garlic and shallots.  The most admired is the amethyst coloured Allium Christophii, known as the Star of Persia which we have planted in between the Lavender Hidcot within the Cut Flower Garden giving the impression of balloons floating above the lavender plants below.

In the Fitzalan Chapel white garden there will be Allium Mont Blanc, a rounded bloom with white, star-shaped flowers and Allium White Cloud which boasts a white head containing hundreds of tiny white flowers.

In the Stumpery Garden we have planted the more unusual alliums such as Allium Hair which, as its name suggests, has green and purple hair-like flowers, the striking dark purple Allium Spider which bears huge purple, rounded flower heads which can measure up to 15cm in diameter looks stunning.

In some areas we have deliberately selected tall ornamental Alliums such as ‘Mount Everest’, ‘Summer Drummer’ to give height and structure to compliment the other plants in our beautiful herbaceous borders.

Included in all ticket types.
