Lupins are a beautiful flower that you will find in many British gardens. Lupins are a staple of British cottage gardens, famed for both their height and colour. Originally hailing from the Mediterranean they are a perennial that will greet you with a gorgeous display year after year. They produce a large flowering spike that is full of colour and each plant can have lots of these spikes leading to a fabulous display.

They will begin to flower around may and can last well into June and like being in full sun. The flowers do go to seed quite quickly but your lupin will continue to produce more and more new spikes. To get the best out of these spikes though it is essential to deadhead the old spikes to give the new ones a chance to flourish. Also cutting your lupins back in autumn can help them the following spring.
