Coming up like weeds this year.
Delightful but they seem to be prolific this year or is it our gardens here on the Isle of Wight? |

Coming up like weeds this year. Delightful but they seem to be prolific this year or is it our gardens here on the Isle of Wight? No they do seem to have had a good year. I've certainly noticed more than ever before and in our own garden they have come up in unexpected places. Interestingly a few plants are obviously hybrids with some polyanthus we had so we have some primrose shaped plants/flowers but with different colours and the opposite. Quite interesting, especially one clump with large flowers. -- Regards. Bob Hobden. Posted to this Newsgroup from the W of London, UK |

Wildflower seed suppliers had their fingers badly burnt in the 1980's when they imported cowslip seed from Holland which had been produced next to polyanthus! At Ashton we kept all native Primula species isolated for seed production - although that didn't stop them hybridising amongst themselves. It is thought that the native oxlip was originally a hybrid between primrose and cowslip. Phil |

I expect that Primula farinosa (a close relative of Primula scotica) doesn't hybridise with polyanthus either. Phil -- SRH |

It is thought that the native oxlip was originally a hybrid between primrose and cowslip. No, that's not quite right. Yes, they will all hybridise, and are fairly promiscuous even in the wild, so that one can argue that they are really only subspecies. My primulas started as polyanthus, and have bred themselves back to something very similar to cowslip (probably over 70+ years). But there are TWO 'oxlips' in the UK: the false oxlip, which is a stable hybrid, and the true oxlip, which is as separate as either primrose or cowslip. So the modern understanding is that we don't have a clue! Of course, as usual, most of the taxonomists are sure that they know, but they aren't all sure of the same thing ....

Firstly, it is expensive. But the real issue is that getting reliable answers from it needs a rigorous approach to analysis, and most modern taxonomy is a discipline that is more akin to that of Miss Whiplash than the statistics I was taught.

I'd like to know why they turn into pink ones. There's a large bank at the bottom of the hill leading up to us and it's covered with sheets of primroses but in just a few areas there are some that have turned pink. I've noticed it here and there in other lanes, too and they're in the wild so not planted by a rogue gardener! -- Sacha www.hillhousenursery.com South Devon |

Plant inheritance is mind-bogglingly complicated, but let's call it 'genes'. My guess is that there is a combination of genes that induces the red, and it is essentially a random variation. And, because it is a combination, it can appear in populations of yellow ones, and yellow ones can arise from the seed of red ones. Regards, Nick Maclaren. |
