Are non native plants bad?

    Space is also finite in the average garden...time to talk to the neighbours too if we want to be more organised. I never said that advice was the end of it all but a good principle to keep in mind. 
    One of the interesting points Ken Thompson ('No Nettles Required') makes is that the differences between gardens is probably more important than busting your hump to offer different habitats in your own garden, and it happens by chance. For instance your garden may be mainly vegetables etc, your neighbour's is mainly just grass with a few matt forming weeds like daisies, the next neighbour has a really big pond, the next neighbour has some fruit trees, and the next house is a rental HMO that just has a mass of nettles and bramble. Any of the gardens in isolation would be lacking or this or that, but as a whole, they form a nice mosaic habitat.

    When my Mum was first diagnosed with cancer, her oncologist told her to try to only eat foods that her grandmother would have eaten. There are people who interpret that to mean a diet like that of England in the 19th Century - i.e. pretty poor - but of course that's not what he meant. He meant to avoid highly processed or industrially produced foods. It wasn't a prohibition on eating mangos, just because her grandmother probably never knew such a thing existed. 
    Personally, I think the same applies to this debate. If you grow plants that are not heavily hybridised to the point where the flowers are sterile or so distorted in form that animals can't access the food they provide, then it's all good. The fact that your average English bumblebee's great great great great great great ........... great grandad wouldn't have met a particular plant that at that time only grew in South Africa doesn't make it less useful or tasty to the bumblebee. As long as it IS the plant - or close to the plant - that was growing in SA.
    There are botanical reasons not to grow species from outside our native ecosystem to do with invasive plants and other imbalances and we do need to be very careful about unintended consequences like JKW. And I completely accept the point about needing native plants AS WELL in our gardens to provide creatures with a full life cycle habitat. But I also think a blanket 'if it didn't grow here 3000 years ago then I don't want it in my garden' is arbitrary and nonsensical from a biodiversity perspective. Who knows whether there used to be bananas growing wild in Devon when the dinosaurs were about? How far back is the line drawn?

    Hi @Jellyfire,

    I'm interested in the point you make about honeybees.
    We keep hives of honeybees in our garden, and so we notice which flowers and trees they visit for pollen and nectar. 
    We also have many types of solitary and bumble bees, and have noticed that they often tend to forage on different plants.
    I think they have different proboscis lengths, and so can access some plants but not all.

    By the way, I'm not sure you can call honeybees domesticated. Ours certainly have a mind of their own and keep us guessing .... but that's part of the fun.

    I only discovered this when watching The Wild Gardener on BBC2 last year (currently on iPlayter and well worth a watch), there was very knowledgeable expert on there who pointed it out. Its basically a competition thing, it varies dependent on number of beehives and also location, basically more bees than flowers available, so less food for all. Not a problem in times of plenty, but when food is scarcer then wild bees suffer.

    Im certainly not saying you shouldn't be keeping your bees by the way, just pointing out that the whole 'perfect for pollinators' initiative has to simplify a very complicated issue to make it digestible.
    Its brilliant that so many people have got that message now though, and I think the whole pollinators element has much more awareness these days, but maybe the next message needs to be about adding a few more native plants for the caterpillars, larvae and less glamorous members of the insect world. There are so many lovely native plants out there which offer a wealth of benefits for all sorts of life, and Im sure huge amounts of people would welcome some into their gardens if only they knew the difference they can make.  

    (European honeybees are a domesticated breed and have been since Egyptian times btw!)

    Thanks @Jellyfire, I'll have a look at that programme.

    Interesting article here about the domestication issue. 
    https://www.buzzaboutbees.net/are-honey-bees-domesticated.html

    It is basically arguing that, unlike some farmed animals, mankind has not altered the Eurpoean honeybee - apis mellifera - whatsoever. They are exactly as they were before the Egyptians started to keep them. They can manage fine in the wild in a tree hollow or a chimney pot without any intervention by a beekeeper.

    It is also suggesting that they are not in competition with "wild" bees.
    There can be a problem though if too many beehives are kept in an area, but the competition for available forage is between the overpopulated honeybees.

    I agree with the point you make about nettles etc for caterpillars. I've got plenty here, and could make a killing potting them up and selling them if they become the next big thing  smiley:

    Good read @Bee witched, and certainly makes a good case for them not being domesticated.

    As to whether they impact wild bees or not, there seems to be strong arguments for either side when you look into it, but in the grand scheme of things I dont think people keeping honey bees is one of the big problems facing insects, and I certainly wouldn't wish to criticise anybody who did. I happily eat honey so have got no grounds to be on a high horse over it. And my guess would be that generally anybody who keeps bees is probably doing plenty of other stuff that helps more than they hinder (if they do in fact hinder at all)

    Was just making the point that its a complicated subject as to how to help. I just find it slightly disheartening whenever there is a discussion about how to do more for wildlife that lots of people seem to take it as being preached to, or that they should be ripping up their flowerbeds in favour of nettles. I pull nettles out in my garden, whilst brilliant for wildlife they are far from in short supply around here, so Id rather give the room to some of the much more attractive, and equally beneficial wildflowers and grasses on offer. It is a garden after all, so its got to work for me as well as the wildlife

    Someone earlier mentioned a "guilt trip". In answer to the OP - please don't have one of those whatever you do. The space has already been requisitioned as part of your property. There will always be the 'holier than thou' crowd who would pass judgement on whatever you do with it. We only have a relatively short life, and it can be cruelly cut short at any moment. So just do what brings you pleasure.

    And FWIW I agree with you.

    Amen. Why start throwing around names and talking about 'guilt'? In the years on the forum I've not once seen a suggestion that people shouldn't grow exotics or enjoy them.

    Lots of people grow their own fruit and veg and love it. I don't feel preached at or judged when the conversation gets on to radishes. I don't grow my own, but am delighted that people do. I don't feel threatened by radishes or feel that people who grow them are "holier than thou". Why on earth would I?
