I have just planted lupin seed, when they are bigger can I put them in a large pot outside and put them in the garden next year.
If your lupine is a perennial, this shouldn't be a problem. Once they've taken hold in the ground, lupine don't like to be moved, but transplanting the seedlings should be fine.
Here's an article on growing lupine: https://www.gardeningknowhow.com/ornamental/flowers/lupine/growing-lupines.htm
My lupin flower has started sprouting leaves from its stem. I’ve never seen this before - is it normal? What should I do with it?
It isn't normal, but mutations can occur. Sometimes they happen out of nowhere, but I would have your soil tested for chemicals, radiation, or other mutagens, just in case.

I am concerned that if they are planted out now they may die
Your climate is, most, similar to our USDA zone 9. Lupines are very cold hardy, down to our USDA zone 4. There won't be too much concern with the cold harming them.
Assuming that your Lupines are suited for your area (that is, if they are able to survive with the lack of the cold temperatures that they like through the Winter), they will do quite well. Just make sure that the temperatures are mild for a few weeks after planting, so that they can establish.
As long as it is not overly hot, they will be fine to plant.
Here is an article to offer more information on these flowers:
They are small - about six inches high. Thank you
If you need to get them into the ground, you may want to choose an area where they'll get some protection from the cold weather that's coming up. Follow the tips in this article to help them stay healthy through the transition from pot to ground: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm. They should take off in the spring.
Please explain this puzzling sentence-"Lupines produce seed which will re-produce more flowers the following year if not removed from the growing lupine." I am a long time gardener and have never heard anything like this. I cannot comprehend what you are saying. Thank you
I think what this author means is this: If you leave the flowers, do not deadhead them, and let the seeds dry and fall, they will grow in the spring and produce more flowers. Deadheading the lupines - removing the flowers when they're finished - also removes the seeds, so they will not drop and produce more plants next year.
been sold the wrong variety. Your answer would be most appreciated thank you It’s got two small flowers but not the colour I was expecting
They should be magenta and purple. The soil needs to be well drained and slightly acidic. I wouldn't panic just yet. If you only got two flowers it may not be mature yet.
I have a healthy lupin but the one if the flower stems is shown below- it's a mutant! Anyone seen this before?!
Symptoms point to Polyploidy. This is just a fancy term that means it is a mutant with multiple sets of genetics in each cell.
Sometimes, when the cell is dividing mistakes are made. Instead of dividing into multiple copies of cells, they merge into a larger single cell. When this happens, you get mutations like this.
Enjoy it. It won't harm anything, and will make for some unique photos!
This article will explain polyploidy:
