We sell plant material in a variety of forms depending on the species, time of year and ease of packaging.

Bulbs

Erythronium bulbs are despatched when they are dormant in mid to late summer. They are easily damaged in transit or during planting if they are in full leaf. We sell them at the best time for you to plant them either in pots or directly in the garden.

Rhizomes and Tubers

Roscoea and Trillium are sent to you bare-rooted when they are virtually dormant. Rhizomes and tubers are underground thickened stem for storing the plants energy.

In the case of Roscoea which are in the ginger family of plants, they have a small rhizome with fleshy, thick, tuberous roots attached similar in appearance to dahlia tubers.

We send both Roscoea and Trillium rhizomes to you with plenty of roots on at the right time to plant them directly into your garden or to pot them up.  The roots are crucial to their successful establishment.

Seeds

Hellebore seeds must be sown as fresh as possible.  We therefore send them to you soon after collection.

Plug Plants

Our Hellebore plugs are young vigorous seedling plants that are despatched to you just as their roots are ready to grow down into a bigger pot.  They need potting up as soon as possible after you receive them.

Pot Plants

Plants grown in pots are ready for planting directly out into your garden.  They can be planted out at almost any time of year as long as they are kept watered in the summer during establishment.

We update our stock on the website regularly and add new plants as they become available

All orders accepted by Twelve Nunns are subject to these terms and conditions of sale. All descriptions, photographs and illustrations contained in this website are accurate in our experience.

Please note our despatch periods. Orders can be placed and paid for outside the despatch times online and by mail order. As we are sending you live plants please let us know if you will be away for more than a couple of days within the despatch times, so that we do not despatch your order.

If a particular item is out of stock we will notify you at the earliest opportunity, giving you plenty of time to select another item or request a refund.

‘Harvington Hellebores®’ are seed grown from carefully selected, hand pollinated plants in an insect free environment to ensure that seeds are of a known colour. Occasional variation in colour and flower form may occur.

Our packaging is designed to protect plants in transit. We take great care to ensure that you receive them in excellent condition. However, if your order arrives damaged, please inform us immediately.

If for whatever reason you wish to cancel the order, please inform us within 7 days of placing the order. If the order has already been despatched, you will be responsible for the cost of returning the plants to us in the condition in which they were sent to you. Once they have been received a refund will be given.

If you have any suggestions or comments, or are not satisfied with the plants or the service that you have received, please contact us in include your order number. Email is preferable because we are a small business and are not always able to get to the phone. Please see the contact page.

Post

We send small parcels by Royal Mail or larger parcels by courier. Please advise us of any days during the despatch periods when you may be away or unable to receive the delivery. Also, do tell us if you would like the parcel leaving in the porch or shed etc – we write this clearly in red on the box.

It is with sincere regret that since Brexit we can no longer send our plants outside of the UK.   We are very sorry not to be able to supply our customers in Europe for the time being but hope that in time we will find a way.

Packaging

Our packaging is nearly all compostable so simply receive your plants, plant them and then walk to your compost bin and smile! You won’t have a heap of packaging for the dustbin lorry to pick up, just some extra food to keep the worms happy 🙂

Despatch Periods for Plant Material

We despatch plant material at the best time of year (in our experience) to ensure you receive it fresh and get the best results. This results in 4-6 week despatch periods for each group of plants, seeds, bulbs or rhizomes. We take orders in advance and during the despatch periods.

There may be some minor adjustments to the despatch periods given below because of seasonal variations.

Roscoea tubers:
March and April as bare root tubers, as potted plants at other times of the year.

Harvington Hellebore® Plug Plants:
Mid-April, through May and June

Harvington Hellebore® Seeds:
During July

Erythronium bulbs:
From July through August and September

Trillium rhizomes:
From September through to early November

Pot Plants

We aim to send out pot plants within 2 weeks of ordering.  The exception to this is during the month of August.  Orders received during August will be sent during the first week of September.

Pre-orders

If you would like to order our plants outside of the despatch periods listed above we now use a pre-order system.

How to Place a Pre-order 

Add the plants you would like to the basket then proceed to the checkout in the normal way.  Payment for pre-orders is needed at the point of ordering, however your plants will then be despatched to you within 14 days after the ‘release date’, e.g.  after 24th March 2023 for Harvington Hellebore® Plug Plants.

You will receive 2 emails, 1 confirming your pre-order,  and another when your order has been despatched. 

Different groups of plants are ready to send at different times of the year and therefore will have different release dates. Please  therefore note the following when pre-ordering:-

• Pre-orders cannot be added to a basket containing plants that are available for despatch now e.g. a product such as  a Hellebore Pot Plant that is available now has to be ordered separately.  
• Pre-orders with different release dates cannot be added to the same basket e.g. Harvington Hellebore® Plug Plants (release date 24 April 2023) and Roscoea tubers (release date  6 March 2023) would need to be ordered separately.  So if, for example, you would like several different Hellebore Plug Plants then these can all be added to the same pre-order, but if you’d like some Roscoea tubers as well then you will need to raise a separate pre-order for these.  This is because we send Plug plants from mid-April to early June, and Roscoea tubers  from March.

We look forward to receiving your pre-orders! 

Twelve Nunns established a plant nursery in south Lincolnshire in 2012. We decided that the plants that we grow for garden centres should be made available by mail order direct to customers.

Penny Dawson owns and runs the business. Her parents, Hugh and Liz Nunn, had a specialist wholesale nursery in the village of Harvington near Evesham as she was growing up until their retirement in 2015. Formerly a Nunn and with the maternal family name of Twelves under threat of extinction, what more was needed to name her business.

The prefix ‘Harvington’ is associated with the plants bred and selected as the very best of their kind by Hugh Nunn in Harvington over the 30 or so years that he was there.  These are now propagated by Penny and the team on the Twelve Nunns nursery.  So if you see a plant with Harvington in its name, you know it began its life here with us.

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.

For any further queries please use our Contacts page.

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!
