We only grow and propagate Delphiniums that have been awarded the Royal Horticultural Society’s Award of Garden Merit (AGM) during trials at RHS Wisley. They are cutting grown, not seed raised and are therefore true to type.  They are selected as the best for growing in British Gardens and are all vigorous varieties.

Our Delphiniums are despatched in 9cm pots from the beginning of July and are available to pre-order from mid April. They are well rooted so will be ready to be plant straight into your garden. We occasionally have some Delphiniums as 2 litre pots during March, so please check our website for availability.

First established by Hugh Nunn and now run by his daughter Penny, Twelve Nunns is a specialist nursery based in South Lincolnshire. We only grow and propagate award winning Delphiniums. We are passionate about the quality of our plants and their garden worthiness.  Please note that the packaging we use is all compostable so simply receive your plants, plant them, and then walk to your compost bin and smile!
