The new Alpine House at Harlow Carr has a plunge bed to be proud of as you may expect from the RHS. This Dionysia Curviflora has been double potted to facilitate watering and it’s flowers will be purple with a white inner ring and dark centre.

The plunge bed is at a good viewing height and the display can be changed as plants develop and seasons change. As a purpose built, alpine house plunge bed there are several features it would be hard to incorporate in my glasshouse but the rake from front to back and the use of rocks builds up height to provide a landscape rather than a flat two dimensional display.

The sand and gravel mixes vary depending on the plants being grown. Some free planting around the plunged pots adds to the attraction of this type of alpine display. The alpine house is climate controlled but much of the daily watering is done by hand before visitors arrive to view the gardens.

I am now keen to develop a better plunge area for my alpines. That is one of the joys or costs of visiting a best of class display like RHS gardens.

Tip – Study the best and think how you can incorporate new ideas in your gardening. The photo below shows how different coloured chippings and grits can work with your display.
