John, Powys

Thank you for the order – in excellent condition. As usual, beautifully packed. If I get as much pleasure from the plants as from the packaging (which I fully expect to do) it will be a great purchase.

Terry, Hereford

Just had to tell you that I purchased some plants from you about 3 or 4 years ago, one of which was Roscoea Harvington Imperial.  It has been flowering for the last 2 months in a 12 inch pot, and is now one of my top plants, and I have had hundreds during my 80 years.  I don’t know if you bred this plant, but what an absolute beauty it is.  Right outside my garden door, first thing I look at each morning to remove any passed blossoms, and it seems to keep producing more without weakening.

Jill, Leatherhead

The hellebores have just been delivered and are currently having a good drink.  I have to write to you to let you know that these 6 plants are in such fantastic condition and were so carefully packed.  I will be shouting to your name out to anyone who I know wants a hellebore or the other plants that you sell.

Planting your Narcissus cyclamineus bulbs 

How to plant 

The bulbs are at least 3 years old and most should flower in the first year. They are supplied in pots because they must be kept damp – unlike most other daffodils which we traditionally buy as dry bulbs.  These delightful petite daffodils are well rooted in their pot.  There are at least 3 bulbs per pot however when planting do not try to separate them. Dig an appropriate size hole and carefully tap out or cut the pot open and try to keep the compost, bulbs and roots intact while planting.  This will minimise damage to the roots and maximise your success.  

Where to plant 

They can be planted in a larger pot with other bulbs and plants; in the front of a border or can be planted in ‘thin’ grassland and naturalised – as on the Alpine Meadow and Rock Garden area at the Royal Horticultural Society’s Garden at Wisley.  

When established,bulbs will become clump forming the longer they are in the ground. They grow best in moist, but well drained soil which is slightly acidic.  If they are happy, they will self-seed and are perfect for naturalising, especially in thin grassland. They prefer dappled shade so do avoid a planting position in full sun.  

Planting your Meconopsis sheldonii ‘Slieve Donard’ 

Where to plant 

Meconopsis prefer a cool and shady position, with some shelter from the wind. They are frost hardy but during the winter protect them from long periods of rain to avoid waterlogging. If in a pot or container, put them in a greenhouse or cold frame to keep them from becoming too wet. This is to imitate their natural habitat in the dryer climates of the Himalayas. 

Compost and feed 

Ensure they are planted in free draining compost or soil. They grow well in neutral to acidic soils. If planting in a pot use ericaceous compost. 

Leaves 

The leaves die back during November/December, and then a rosette of new leaves start to form in early Spring. If in a pot or container, water them well as the leaves emerge and keep them damp throughout the Spring and Summer. Ensure they don’t dry out at any point during the growing season. 

Cut off the old flowers as they fade to encourage new shoots to form. 

Planting your Harvington Hellebores® Pot Plants 

How to plant 

Please allow some light and air into your plants immediately and keep them in a cool light place.  Ensure that the plants are kept moist at all times and plant them as soon as possible after receiving them.   

Prepare the soil well: dig over an area, add some compost or well-rotted manure and then plant them. Take care not to damage the roots and gently firm the soil around the plant. Keep the area around them weed free. Always water your plants in when you plant them either in a pot or in the garden.  Remember hellebores are hardy plants and so they should be kept outside, not in a greenhouse. 

Where to plant 

Hellebores thrive in dappled shade in soil that is well cultivated, fertile and always moist during the main growing period. 

Compost and feed 

Hellebores are hungry plants. Use a general purpose, free draining compost or well-rotted manure when planting. The main growing periods are during the Spring and Autumn so use a liquid feed every 2 – 3 weeks during April and May, and again in September. As Autumn approaches, top dressing them around the root zone with some bone meal is advisable but avoid putting this near the crown of the plant. A general-purpose fertilizer can then be applied in late winter.  

Leaves 

Hellebore leaves are ‘evergreen’ but do eventually look past their best, usually in late Winter. They can then be cut off and new growth will take place.  It is important to keep the crown of the plant open by cutting back any dead foliage and avoiding any build-up of soil or leaf litter. We do advise however leaving the leaves on as long as they look green and healthy. 

Occasional problems 

Black Spot:  Hellebores sometime suffer from fungal disease which causes black patches on their leaves. The easiest way to prevent this or treat if already present is to spray with a fungicide like Liquid Copper or something like Roseclear at the same time as you treat your roses. 

Aphids:  Sometimes aphids enjoy feeding on Hellebores. Use an appropriate control spray from your local garden centre or hardware store to prevent an infestation. 

Please note:  Hellebores can cause skin irritation and are harmful if eaten 

Lois, Monmouth

Just to say thank you so much for the lovely plants received safely today. They are so healthy and now I have found you I shall certainly be back.

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.
