Question: primrose seeds

hi I am Giovanna I read many manuals but no one satisfies my problem ... what should I do and how can I do to sow the primroses and get hybrids ?? Thanks so much

Answer: semi primulas

Dear Giovanna,
primroses commonly grown in nurseries and in the garden belong to hybrids of various types, produced over the decades, with flowers of every possible color (including black), sometimes even double or stradoppi. Not all of these hybrids produce seeds, but most do, and they also tend to self hybridize to each other, simply because the wind or bees carry their pollen. It is therefore quite easy to obtain primrose seeds from our plants on the terrace, or in sachets sold in specialized shops. Unfortunately, starting from already hybrid plants, it is not predictable what will be the characters of the plants obtained from seed, because they will not always have the flowering characteristics of the plant that carried the seeds, or of the mother plant. So, taking the seeds from our small plants, on the one hand it is very likely that seeds are taken that are the result of self-hybridization, on the other hand it is not said that they give plants identical to the mother plant.
To try to hybridize home-made a primula, we will not have to do anything but take pollen from a small plant (a soft brush is used) and brush it on the flowers of another plant, with completely different flowers. It is important to practice this operation on flowers that have been opened for a few hours, because if we do it on flowers that have bloomed for days, it is likely that they have already been fertilized; in addition to this, if we want the seeds to be the result of our home hybridization, we will have to cover the flowers pollinated with muslin, or with woven fabric, to prevent the bees or the wind from repeating pollination.
As said before, you will never know what the result will be, until you have grown the young seedlings; in the sense: if you take pollen from a double-flowered pink primrose, and place it on simple and candid primrose flowers, you cannot expect to obtain plants with pale pink double primroses. This is because the genetic variability of your plants is already very high at the start, since their ancestors are very many, given that the primroses have already been hybridized and crossed dozens of times.
You can, however, try to look for seeds of botanical species, in order to try to breed more pure individuals.
Primula seeds are sown when the nocturnal lows are not excessively high, therefore from October to March-April, approximately; this is because if the lows are excessively high these plants tend not to germinate, except after having been placed in the cold in the refrigerator.
To avoid having to vernalize the seeds, they are sown with fresh.
Prepare a seed bed made up of peat and sand in equal parts, well moist (water it before sowing), and place the seeds well spaced (if you can); keep the seedbed in a cool place, with temperatures close to 5-8 ° C, and it often vaporizes the mixture, so as to keep it always moist; Your seeds should take about a couple of weeks to germinate.
