shown how to build their own allergy free garden at the world famous Chelsea Flower Show in London this week.\u003cbr/\u003eIt's of special interest to the one in five people who regularly figh back tears, not from joy, but from hay fever. \u003cbr/\u003eIt's nectar to the bees, but it's also the blight of every summer for millions of people around the world.\u003cbr/\u003eJust when nature is at her most beautiful, pollen is at its most irritating.\u003cbr/\u003eIt's everywhere.\u003cbr/\u003eThe trees are the first culprits on the British pollen calendar, followed by flowers, grasses and crops well into September.\u003cbr/\u003eGovernment figures claim a fifth of the UK population suffer from allergic rhinitis, known commonly as hay fever.\u003cbr/\u003eCambridge University has created this picturesque meadow at it's Botanical Gardens.\u003cbr/\u003eHere the bluebells, buttercups and daisies are give as much pride of place at the more high maintenance and rarer blooms.\u003cbr/\u003eBut if you suffer from hay fever sitting here would be a very unpleasant experience.\u003cbr/\u003eIf you suffer from asthma it can even be dangerous.\u003cbr/\u003eIt's symptoms include sneezing, itchy and watering eyes and a stuffy nose.\u003cbr/\u003eThey're caused when an allergic trigger like pollen makes the body produce antibodies.\u003cbr/\u003eThe scented and the bee gardens here in Cambridge are especially grown to attract the local wildlife, so there's a lot of pollen around.\u003cbr/\u003eBut in the glasshouses round the back, the local botanists with the Royal Society of Pathologists are preparing their garden ahead of this year's Chelsea Flower show.\u003cbr/\u003eIt'll show allergy sufferers which plants they can enjoy and which to steer clear of.\u003cbr/\u003eOne bed has flowers and plants which are known to contain allergens and another contains plants which are easier on people who are sensitive to pollen.\u003cbr/\u003eDr. Tim Wreghitt, former president of the Royal College of Pathology says: \"The message is that there are certain plants which we'll be showing in one section of the stand that are associated with allergy therefore if you have hayfever, or asthma don't plant them in your garden, yet there are other plants like the ones behind me which you can choose, which are as colourful as beautiful which do not have pollen and are okay to use.\"\u003cbr/\u003eBoth Britain's Department of Health and the Royal College of Pathologists agree that the number of allergy sufferers in the UK is increasing, but the reasons are not yet fully understood.\u003cbr/\u003eImmunologists are researching whether there genetic programming could be blamed.\u003cbr/\u003eWreghitt says: \"The principal reason, probably, is the fact that we live in a desanitised world people spray this stuff all over the place to sterilise this and clean that and when I was younger many years ago we used to pick things, you know eat dirt pick things off the floor, no-one worried too much now people would be horrified. Oh it's dirty in fact you know a lot of us think that a bit of dirt isn't a bad thing it does prime your immune response.\"\u003cbr/\u003eMost of Britain is officially in drought conditions, but gardeners have complained that the cloud, the rain and precious little sun in recent week have hampered attempts to get a dramatic floral display.\u003cbr/\u003eSimon Wallis is a senior gardener at Cambridge and has been helping to design the allergy garden.\u003cbr/\u003eHe says: \"We had a lot of rain and not much sunshine. I think we had a couple, or maybe a week of sunshine in March and we had almost four weeks of continual cloud and rain so that's definitely had an effect on getting plants into flower on time and Chelsea (flower show) is pretty early anyway.\"\u003cbr/\u003eLavender, Lillies, ferns, thistles and ornamental grasses are the greatest culprits according to Wallis.\u003cbr/\u003eHe says \"A lot of plants that are wind pollinated is a really good key to bad plants, they produce masses of pollen, it gets in the air easily transferable, we breathe it in so a lot of plants like that and also plants that produce heavy amounts of pollen, stuff like the lilly here and also again stuff in the daisy family's particularly bad for producing pollen that irritates people.\"\u003cbr/\u003eWallis says we shouldn't simply be assessing plants for pollen dispersal. \u003cbr/\u003ePointing to the Morning Glory he says \"you can see it's clothed in these hairs and they're really irritable, so if you kind of brush that, or walk past it they're going to get into the air and they'll get down into the back of your throat and cause breathing problems.\"\u003cbr/\u003eOn his finger is the residue of the the plant's barbs.\u003cbr/\u003eWallis says it is possible to avoid pollen altogether. \u003cbr/\u003eHe says: \"Fill your garden with double flowers because the majority of them don't have pollen so they can't really self fertilise, they don't have pollen so you're not going to have a pollen issue, so double flowers, I'm not a great fan, but double flowers are a good way to go, or try and get flowers that are insect pollinated, that's always a good idea so that pollen is taken away from the plant by an insect, or a bird, rather than mass produced and flowing through the air.\"\u003cbr/\u003eOutside the glasshouse the bees are already busy collecting pollen.\u003cbr/\u003eThe Chelsea Flower Show ends on 26 May 2012.\u003cbr/\u003eCambridge, UK, May 17, 2012\u003cbr/\u003e1.
