New hybrids of Harvington Roscoea featured in Gardens Illustrated Small Garden Special August 2024.

Introduce a touch of exotic beauty to your garden with our selection of Harvington Roscoea. With a form and flower similar to the orchid, many of these remarkable plants have been featured in this month’s Gardens Illustrated magazine Small Gardens Special (August 2024). Matthew Biggs has written an extremely informative piece on how the Roscoea genus was introduced to this country. Following some careful selection….

“a host of delectable new hybrids and ease of cultivation means that everyone can welcome this exquisite, connoisseurs’ plant into their own garden.”

(Matthew Biggs, Gardens Illustrated August 2024, photographs by Clive Nichols).

Our selection of Roscoea include a number with the prefix ‘Harvington’.  These are a set of distinctive plants bred by Hugh Nunn in the Vale of Evesham and selected for their beauty, vigour and garden worthiness.  Several have been awarded the Royal Horticultural Society’s Award of Garden Merit (AGM) in recognition of these characteristics.

After 15 years of dedicated selection and reselection, we are now releasing more stunning hybrids. Many of these outstanding plants have been featured in the Garden’s Illustrated magazine article, along with others from the Harvington Roscoea family.

Our Roscoea are robust, clump-forming, and vigorous plants, they can thrive anywhere in the British Isles when positioned in dappled shade with moist, free-draining soil. They are well-suited for woodland gardens, shaded borders, or as part of a rock garden where its unique and exotic blooms can be appreciated up close. They will also happily grow in a large container in a shaded corner of a patio.

Our well bred Erythroniums – full of grace, poise and charm.

Last year we were delighted to introduce three new members of the Harvington Erythronium family, namely ‘Harvington Lilli’, ‘Harvington Elizabeth’ and ‘Harvington Imogen’ .

Gardens Illustrated Magazine April 2023
Gardens Illustrated Magazine April 2023

‘Gardens Illustrated’ , as part of their 30th anniversary edition published in 2023, wrote a wonderful piece about our Harvington Erythronium breeding programme here at Twelve Nunns. Started by Hugh and Liz Nunn from a nursery based in the village of Harvington during the mid 1980’s, the article explained how this programme ‘spans two generations and has taken more than 20 years of careful, meticulous selection to create a three new Harvington erythroniums. And now that Harvington trio is finally ready to meet the world.’

But why breed Erythroniums?

‘They’ve got everything: grace, poise and charm.’ That, and their rarity value, makes them compelling to grow,” says Penny. And just like that, the compulsion to create something wonderful is inherited from one generation to the next.’ (Alys Fowler, Gardens Illustrated April 2023). 

Erythronium are quite simply stunning! Flowering from early March, their upturned petals reveal delicate markings and brightly contrasting stamen atop of slim stems, each stem producing three flowers, contrasting well with their mottled foliage.

But don’t be deceived, these are easy to grow, as long as they are positioned in a cool, dapple-shaded area with protection from strong winds.

Erythronium will clump up beautifully for you with a little care. Once Erythronium bulbs are planted in groups in your garden they will provide colour next Spring. In time, if the soil around the flowering bulbs is left undisturbed, they will set seed and begin to naturalise.

We are delighted to be able to offer you a chance to experience these magnificent erythronium yourselves. Along with our Harvington Erythroniums, including our three new family members, we also have the rarely available Erythronium hendersonii and Erythronium howellii, but only whilst stocks last.

For those of you who would like to make a more eye catching display, we have some great offers on E.White Beauty, E.Old Aberdeen and E.Harvington Sunshine.

We send all our Erythronium as dormant, freshly lifted, flowering size bulbs from July through to September ready for potting up or planting directly into the garden. Each flowering size bulb has been carefully grown for at least 4 years.

We know you love them as much as we do!

Twelve Nunns Green Credentials

We are constantly reviewing what we can do to improve Twelve Nunns Green Credentials, working to help save our environment as well as your pennies! We are proud of what we have achieved so far.

Twelve Nunns Green Credentials

Packaging – those of you whom have bought from us before will be aware that the packaging we use is all recyclable – right down to the the gummed, compostable paper tape we use to seal our boxes (no need to strip off any vinyl tape before recycling or composting). Our packaging solutions are as a result of a continual evolution of ideas.

Saving compost – a 9cm pot only uses 0.5 litres of compost. Compare this to the 2 litres of compost if you buy a plant at a garden centre in a 2 litre pot. And our freshly lifted bare rooted bulbs only require a handful of coir to protect them during transit – this all helps save our precious natural resources. And of course this really helps you save your pennies!

The plants we send to you from Twelve Nunns are either in small pots or are supplied as freshly lifted bare root rhizomes, bulbs and tubers. We breed, propagate and grow all of the plants and bulbs here on our Lincolnshire nursery.

Saving plastic – smaller pots mean less plastic. We are working on removing plastic completely from our deliveries, in terms of both pots and labels. We are planning to replace our labels with a fully recyclable paper based product.

Twelve Nunns Green Credentials

We are also very excited about a product we have discovered recently called a wool pot that is produced in the UK. Along with a wool based topping, these provide exactly the type of protective packaging the plants need to ensure they reach you in tip top condition. They can be recycled and are compostable. We work in a village surrounded by sheep farmers, so making use of a bi-product that is often wasted or undervalued seems a good idea to us.

Saving fuel (so less air pollution) – lighter, smaller boxes that weigh less mean less fuel is needed to transport them.

We passionately believe that all these savings are crucially needed for the future health and stability of our environment. By following our Twelve Nunns Green Credentials we are also helping to support our farming community. By buying our plants you are playing a part in a greener future.

Growing Trillium and Arisaema in the AGS Journal

The June edition of the Alpine Garden Society AGS Journal, offers a valuable insight into growing Trillium and Arisaema.

Anyone who subscribes to the The Alpine Garden Society (AGS) receives ‘The Alpine Gardener’, the quarterly journal packed full of beautiful photographs illustrating interesting and informative articles. There are nuggets of information from expert growers who have spent many years finding ways to cultivate more unusual plants. It allows us as the reader to share in their journeys, to gain a greater understanding of plants that are familiar to us, as well as being introduced to many that aren’t.

In June’s edition we were particularly interested in two articles that align with our own specialisms Trillium and Arisaema.

Paddy Tobin lays bare his extensive journey with Trillium and how he come to appreciate them as plants that will flourish. As Paddy states,

‘These plants changed my experience of and attitude to trilliums completely – now I had plants that would grow and increase and make a decent contribution to the garden’ (page 169 The Alpine Gardener June 2023).

His earlier experiences were disappointing, working with dried rhizomes that failed to flourish. Using healthier rhizomes he quickly realised that,

‘These trilliums were not the Cinderella plants I had grown poorly for years, but ones which were worth their place in the garden for their vigour, performance and beauty’ (page 169 The Alpine Gardener June 2023).

He mentions some varieties that have done particularly well, as his ‘Star garden performers’ and ‘US natives’. One of his ‘Star garden performers’ is Trillium chloropetalum.

Here at Twelve Nunns, we have a selection of these varieties available to pre-order now. They are sent as freshly lifted, healthy Trillium rhizomes with live roots in moist packing material.  Our rhizomes are at least 4 years old.  Given the right situation and soil they should flower after 1 year of planting.

Robert Rolfe then provides some wonderful insights into the world of Arisaema, focusing on a number of species, the choicest of which is Arisaema candidissimum. Discussing the history of the cultivation of Arisaema he notes that:-

A. candidissimum was (to quote from EB Anderson’s Hardy Bulbs, published in 1964) for a long time “the only species …available in the ordinary course of events, though this is a very beautiful one“. If you choose just one, choose this.’ (Page 214 The Alpine Gardener June 2023)

We have Arisaema candidissimum available to purchase now, click here for more details.

The Alpine Garden Society (AGS) are an international, UK based, charitable organisation primarily concerned with the cultivation of alpine and mountain plants from around the world. The AGS is also involved in the study and conservation of alpine plants in the wild. Click here for more information about the Society.
