How to grow oenothera (gaura)

How to grow oenothera (gaura)


As the garden takes on its late summer/early autumn appearance; fading colours, bleached grasses and architectural seedheads, we take a look at a genus producing subtle flowers which don’t look out of place in a garden teetering on the edge of its seasonal shift.

Oenothera

Originating from the Americas, growing in open, sandy and rocky areas, oenothera is at home growing in our Gravel Garden and other free draining spots across Beth’s garden flowering all summer long. We grow perennial forms here, plants from the old oenothera genus (evening primrose) with saucer-shaped flowers, and those previously known as gaura which produce masses of delicate, star-shaped flowers.

A favourite for late season interest is Oenothera lindheimeri, whose moth-like flowers hover above and among other sun-loving plants such as Euphorbia epithymoides, Verbena bonariensis and Pseudodictamnus acetabulosus.

 

Wildlife credentials with Dr Chris Gibson

The flowers of the majority of species are most open and fragrant in the evening when they are visited mainly by the wasps and moths that are active at that time of the day. Some forms, especially those formerly called gaura, flower by day and are much visited by both bumblebees and butterflies. In autumn, if they are not 'tidied up', the spikes of seed pods may be visited by goldfinches and other seed-eaters. Several species and hybrids are now to be found naturalized widely, especially in the lowlands of England and Wales, on brownfield sites and sand-dunes.
