wildflowers

Pulsatilla, Sanguisorba, Wild Strawberry and Ivy

are all UK natives.

Blue Chicory is probably a native too.

If not, it's certainly been growing in the UK since before the Romans were here.

Even if they were non native botanically, it's possible to source British grown specimens of practically everything if you're willing to pay the extra cost for home grown plants

. It's not British grown banana palms from a reputable grower that is the problem but cheap, badly looked after,

mass shipments of 'English' lavender to supermarkets

(it's not at all English btw).

In general there is no great benefit in growing only the extremely limited range of native plants in your garden.

Some insect species are plant specific and if you wish to do the research and help a specific local species that's great,

but the majority of invertebrates are as happy on plants from China as they are on UK natives and in fact increasing the diversity of the plant range makes us,

and them,

more resilient to climate change.

Changes in weather mean that animal

and plant distributions are moving.

Aimals that would previously have been asleep or overseas in the dead of winter are now out and about.

Planting winter flowering, botanically foreign plants provides them with important food at a time when, in a garden of UK natives, they would starve.

Planting flowers from warmer climates feeds our insect life through and after a summer heatwave when many UK natives have died.

Finally, since you clearly don't know a native UK wild flower when you see one,

  Almost all 'traditional English' garden flowers are non native - we only have 1400 native species in the UK and (and well done at directing some xenophobic abuse at five of those!). pretty much all of our food crops are foreign.
