Top 50 Plants for a White Garden White flowering plants to create a sweet-scented, serene garden loved by insects both by day and by night List Curated by Thomas McBride From research data collected and collated at the National Botanic Garden of Wales NB: Butterflies and Moths are not studied at the NBGW so any data on nectar plants beneficial for them is taken from Butterfly Conservation 51 Photo: Will Billlium (Flickr) Introduction A White Garden is a perfect way to create a more serene, peaceful section within a larger garden. It can work well enclosed with hedges if you have a medium-sized garden with several garden ‘rooms’ or as a much larger open space within a large garden. If you have a smaller garden, you may wish simply to use this list to pick white flowers to grow in your border. A white garden is usually a year- round investment so, unlike a hot border, it is great to select flowers that will cover all or most of the seasons, hence, a wide variety are included on this list including a few larger shrubs. White gardens usually work best in fairly dry, well draining soil but may be sunny or in partial shade. Plants As with most gardens, choosing a variety of plants of different heights is important. Place shrubs and tall perennials at the back of the border and smaller plants towards the front. White flowers often have a strong scent as it makes up for the lack of petal colour to attract pollinators. Keep scent in mind when choosing plants as it can add an additional level to your garden. Many of these plants will also attract moths and nocturnal insects.

H1b - Minimum 10ºC Plants without a thermometer symbol are fully hardy in the severest UK Winter; equating to H5 or hardier. H1c - Minimum 5ºC Plants with a coloured thermometer symbol are hardy to varying degrees as follows: H2 - Minimum 1ºC H3 - Minimum -5ºC H4 - Minimum -10ºC H5 - Minimum -15ºC Almost Hardy Half-Hardy Not Frost Hardy Not Hardy (H4) (H3) (H2) (H1) iii Pollinators Our data on pollinators has been collected from studies spanning over a decade. Pollinator symbols appear when plants are proven to be good nectar (a) (b) plants for certain insects. It should be noted that all bee and hoverfly data is ours but lepidoptera data is taken from Butterfly Conservation. Our data spans a wide range of different insect species.
