Pink bluebells
This year we have one clump of pink bluebells when we have never had any
before, anywhere. Does anyone know how this happens? Garden Banter does not have permission to use my posts. Join uk.rec.gardening instead. -- Sacha http://www.hillhousenursery.co.uk South Devon Garden Banter does not have permission to use my posts. (remove weeds from address) |

Pink bluebells
From http://www.bbc.co.uk/radio4/gqt/fshe...heetsq6.shtml:
Question from Pauline Alsop: Why did one of my bluebells turn pink this year? I transplanted them 3 years ago and they've always been blue. Bunny: There's a general consensus of opinion that if you plant them upside down they will change colour. Maybe a squirrel dug it up, turned it upside down, and pushed it back in the wrong way! Anne: In natural populations you do get the odd pink or white bluebell, and I think this one of yours has always been pink, it's just that it happened to flower this year. It may have arisen from seed, or vegetatively by bulbill. I don't think it has changed colour, it is just a natural thing that bluebells will do. Pippa: Earlier this year in the woods near my home there was a definite sudden incidence of white bluebells. I've known those woods quite well now for six years and I've not seen a single white one before, and I'm sure it's just a case of seedlings arising. They can be pollinated by all sorts of other bluebells from other areas, and as Anne says, there is a tendency for them to do that sometimes and I think pink is just another variation. -- Baal I smile and go off waving (Amiably) - for that's my way "Sacha" wrote in message . uk...

Sometimes a plant with pink flowers can produce a couple of white ones. Greg -- You may ask yourself, how do I work this? No ficus = no spam |

It's a bit like some of the wild primroses we see here and there. Some are a true pink or even deeper while all around are the usual yellow. -- Sacha http://www.hillhousenursery.co.uk (remove weeds from address) Garden Banter does not have permission to use my posts.

Pink bluebells
In message , Sacha
writes This year we have one clump of pink bluebells when we have never had any before, anywhere. Does anyone know how this happens? I'd guess that this is a seedling which is displaying a recessive trait. Flower colour depends on several factors, among which are the nature and concentration of the pigments involved, and the concentration of Hydrogen (acidity) and other ions in the environment in which they are stored. For example, Hydrangea is well known for the flower colour varying with soil chemistry. Presumably Hydrangea doesn't maintain its pigments in a controlled chemical environment. Similarly a bluebell could have a broken enzyme, leading to the chemical environment in which its pigments are held not being controlled, and therefore a change in colour. Alternatively, pigments are produced, one from another, in a chain of reactions, catalysed by various enzymes. If one of the enzymes is broken the end result of the change of reactions is a different pigment, with a consequent change in flower colour. -- Stewart Robert Hinsley |

Do you think our pink bluebells are more likely to be the Spanish ones. I haven't had time to do a close inspection yet but I'll get out there today. We were driving home across Dartmoor on Saturday and had the great pleasure of seeing huge masses of English bluebells in the hedgerows, along with campion and stitchwort. It was the most beautiful sight. -- Sacha http://www.hillhousenursery.co.uk (remove weeds from address) Garden Banter does not have permission to use my posts. Join uk.rec.gardening instead. |

It was the most beautiful sight. I am under the impression that the white and pink variants occur in parallel in both Common and Spanish Bluebells. There are a number of other characters that distinguish the two species - URL:http://www.google.com/search?num=100&hl=en&q=English+Spanish+bluebell will find you text on that subject, but that will not necessarily apply to all hybrids - if you've got some introgression into a population of Common Bluebells all you can do is rogue obvious hybrids as they occur. I expect that pink and white variants occur more frequently in populations grown from cultivated stock, rather than from wild stock, as variants have been selected for horticultural use in the past. -- Stewart Robert Hinsley |

I expect that pink and white variants occur more frequently in populations grown from cultivated stock, rather than from wild stock, as variants have been selected for horticultural use in the past. There's an interesting and attractive variant naturalised at the Gelli Aur country park near Carmarthen. This is white, with a narrow streak of deep pink down the middle of each "petal". As far as I remember, last time I was there the large colony still hadn't been visibly cross-pollinated with ordinary blue ones. I imagine the group must have been planted in Victorian times when the arboretum was set up, so this represents a remarkable survival. I mentioned it to a senior member of staff, hoping that they might take steps to have the population bulked up for sale or preservation, but I don't think they did anything about it. -- Mike. -- Posted via a free Usenet account from http://www.teranews.com |

I'm pretty sure that you get pink variants of english bluebells (and I can remember seeing the occasional one back in the 50s in wild bluebell populations when spanish bluebells were far less common in this country), but I think that pink and white variants are far more common amongst the Spanish bluebells. Whether this is true in the wild population or whether it is, as you suggest, a result of cultivation and selection, I don't know. Plantlife has more information on its page, including an identification chart and the report of their recent survey of bluebell populations - worth a read, but only if you are on broadband - it has a lot of large pictures! http://www.plantlife.org.uk/ -- Kay |
