I have just aquired a few lupin seeds, do they require any special treatment before sowing.
Keep them cool then sow around March, kitchen worktop of greenhouse, they need no special treatment, they germinate easily.
I recently went to Ushuaia, the most southerly town in the world. It is freezing cold yet lupins - which are originally from Canada - grew there in profusion. Don't waste your precious windowsill space, sow them out of doors in mid-September where you want them to grow. They will germinate in Spring. Don't worry if they do so earlier. They really are very hardy. Good luck. Ian
Due to slug problems, I now treat Lupins as biennials, raising new plants from a June sowing, planting out the following spring.
This was the method that Christopher Lloyd recommended, although he did it so that he could get rid of the tatty plants after flowering, so he could replace them with something more interesting.
Best way Doc, anytime from March to June is good, if I sowed mine direct I'd never see them again unless I covered the area in pellets, and even then you have to transplant them if they do grow, much better to get them to big plants in 6" pots before putting them out.
Ingle, what suits in your country really doesn't work in the UK.
Well I think Tierra del Fuego and Canada is colder than England! Just for the record, I can't grow lupins here - way too warm.

Treating them as biannuals......you are missing the fabulous flourish of flower stems which occur about year 3 and 4.....
If you plant 2 or 3 together, you get the fabulous flower flush from year 1, then replace them as the foliage gets tatty.
