I reckon that even if the Blueberry plant didn't produce lovely tasty berries, people would still grow it - for its ornamental qualities. At this time of year, Blueberry foliage can be stunningly beautiful. I have assembled a little collection of photos that will hopefully prove the point:
This year the Autumn has so far been very mild. We have not had a lot of strong wind or heavy rain, and the temperature has not yet dipped very low (still no frost here, for instance). This is all set to change tomorrow or Monday, according to the weather forecast, with a big storm making its way towards us across the Atlantic... For the time being though, we have one more chance to enjoy the Autumn colours before the leaves finally get ripped off by the wind. If I find the time to do so, I think I will take down my last lot of bean-poles - the ones supporting the faithful "Cobra" French Beans. If I don't, I expect the gale will take them down for me!
My Blueberry plants (I now have six) are all "freebies" from magazines - ones for which you only pay Post and Packing charges. Some of the plants I have acquired in this way have been surprisingly good. Definitely not "clearance stock" rubbish. Next year I hope to get my first few berries from a new one called "Pink Lemonade", which produces pink berries instead of the normal dark blue. Should be interesting.
I have read recently that Blueberries do best if their roots are not too cramped, so in the Spring I shall be re-potting a couple of mine which have grown a lot since I first got them.
