Mount Congreve’s Magnificent Magnolias


Mount Congreve Gardens must be one of the very best places in the world to see magnolias. There are three spectacular plantings of magnolias in the garden: the first and original planting was on the terrace below the house where we can see Magnolia campbellii, Magnolia veitchii and Magnolia sprengeri var diva among others, all now mature and impressive trees. This planting is best viewed from an elevated spot near The Temple where one can look along the top of the canopy of this planting and see magnificent planting one could not encounter anywhere else in the world.

The Dilemma of Respecting the Elderly!

Some gardens, by reason of their history and previous owners, will have plants which are of great historic and horticultural significance. Their loss might be a great tragedy but their continued presence can be both a great burden of responsibility and an impediment to the development of the area as a garden.

The National Botanic Gardens at Kilmacurragh are home to many magnificent plants



Gardeners of my generation will recall the “miniature” conifer and heather fashion trend in gardening in the 1970s and will, probably, have also found, like me, that those “miniature” conifers did not always behave to their description. The day comes when the mind is finally steeled and the decision is taken to remove them. They leave a gap and are a loss to some degree, yet they open opportunities for the gardener to plan anew, to introduce new plants and for the garden to remain vibrant and interesting.

However, when the plants in question are historically significant the gardener is faced with a dilemma. It was a visit in the last few days to the National Botanic Gardens at Kilmacurragh, Co. Wicklow, which brought these thoughts to mind. The gardens have an outstanding and historically significant collection of plants. Here we can see plants such as the weeping cedar of Goa, Cupressus lusitanica ‘Glauca Pendula’, planted between 1820 and 1840 and the peculiar ash, Fraxinus excelsior ‘Monstrosa’, a tree which was noted as being 1 foot tall in 1840!

When Thomas and Janet Acton took on Kilmacurragh in 1854 they planted with enthusiasm and with the advice of David Moore of the Royal Botanic Gardens at Glasnevin furnished the garden with the choicest plants. The association with Glasnevin continued with Sir Frederick Moore and the planting riches of Kilmacurragh continued to expand, especially  to give a home to those plants which the alkaline soil in Glasnevin did not suit. Sir Joseph Hooker’s 1849 collection of rhododendron seed in the Sikkim Himalaya, after germination at Glasnevin, were grown on in the suitably acidic soil of Kilmacurragh, and developed into Europe’s most comprehensive collection of rhododendrons from Sikkim, Bhutan and Nepal. Many of these original rhododendrons are still in the garden – the original plants, not subsequent propagated generations, the original plants and so of extreme value for their historical significance and association with such wonderful past generations of Irish gardeners and I wonder if they are a blessing or an impediment to Kilmacurragh’s present day gardeners.


The Broad Walk might serve to consider this thought. It was laid out to the rear of the house by Thomas and Janet Acton in the early 1870s. At the time it was planted with alternate Irish yews, Taxus baccata ‘Fastigiata’, the tall and bright red Rhododendron ‘Altaclerense’ and Rhododendron ‘Cunningham’s White’ which is lower growing. Given the passage of time the plants, especially those of Rhododendron ‘Altaclerense’, are now quite enormous both in height and in width so that The Broad Walk is now not as broad as it once was and here is the quandary: Should the garden plants or the garden design take precedence?

At present, Kilmacurragh has a significant collection of plants but the garden layout has become somewhat overshadowed and overcrowded. We see the same problem with those who are more plant collectors than garden makers; it can be challenging to accommodate a plant collection within a satisfactory garden design.

What will happen at Kilmacurragh? I really don’t know but suspect that, as the present curator is an enthusiastic plantsman, these venerable old plants will continue to be treasured for as long as their good health allows and we may enjoy the garden with them for it would not be the same without them.

What a Diva!


Impossibly beautiful, fabulously elegant, deep rose-pink from head to toe and with a sensational presence which effortlessly dominated the garden – this was quite an encounter!

I’m sure you all have had  moments when visiting a garden when you knew you had come on something supremely special, be it brilliant design, captivating plant association or, as with me today, a single plant which simply took your breath away.

Magnolia sprengeri 'Diva' (1)
First glimpse – interesting! 

We entered the garden at Lismore Castle and caught a glimpse of colour at the far end of the Lower Garden, near the Berlin Wall, which immediately drew us along to investigate. It was obviously a magnolia but, my goodness, what a colour!

Magnolia sprengeri 'Diva' (3)
Looking more and more promising! 

We moved along, giving little attention to other plants along the way and our rush along was well worthwhile.

Magnolia sprengeri 'Diva' (5)
It all its glory and looking fabulous – Magnolia sprengeri var. diva!

The first view of the entire tree was breathtaking; this was a truly outstanding magnolia and one of the most beautiful I have ever seen – Magnolia sprengeri var. diva!

The plant hunter, Ernest Henry Wilson (1876 – 1930) collected magnolia seed while on his first plant hunting expedition, on behalf of the famous Veitch Nurseries, in south-western China in the autumn of 1900. Plants raised from this collection were put up for sale in 1913 and one was bought by J. C. Williams of Caerhays Castle in Cornwall. When it flowered in 1919 it turned out to have very attractive deep rose-pink flowers while all the other plants produced white flowers. J. C. Williams’ specimen was named Magnolia sprengeri var. diva while the others had Magnolias sprengeri var. elongata. It was named, by the way for the German botanist, Carl Ludwig Sprenger (1846 – 1917) who was a partner in the Dammann & Co. Nursery of San Giovanni a Teduccio, Naples.

As well as its large and beautifully coloured flowers, Magnolia sprengeri var. diva is also strongly fragrant and this gathered wonderfully around the tree in the Lower Garden at Lismore Castle as it is planted in a natural hollow which escapes the breeze and allows the fragrance to linger. What a tree!

There were other plants and areas of interest in the gardens at Lismore Castle and here is a short slideshow to give you a flavour of our day out. It is worthwhile visiting the gardens right through the year so make your way there at some stage.

Three Days to Eternity

Dicentra spectabilis
Dicentra spectabilis

We spend time in the garden every day, even on bad-weather days, if only to have a quick peep to see what is in flower, what is doing well, or not, etc. We weren’t out over the weekend as we had an indoor attraction far more important than the garden – a six-month old grandchild in the house! – and a walk around the garden today was a time to notice how much can change in a very few days.

Erythronium 'Susannah' (1)
Erythronium ‘Susannah’

The grass is looking a little fluffy even though I cut it only last week, a real sign that the soil has warmed up and that the garden will be into full and profuse growth from now on; Frittilaria imperialis have come into flower;  the orchids are above ground in the beds and appear to have multiplied – they had been planted as single roots last year so it is good to see them begin to bulk up again; that bergenia that I was told came from Carmel Duignan’s garden has flowers – nice purple foliage and pink flowers, promising!; the first tulips are out in the garden – a yellow one whose name is long lost, T. kaufmanniana ‘Heart’s Delight’ is fully open; the Skunk Cabbage, Lysichiton americanus, is well into growth showing its yellow spathes; Leucojum vernum are all out of flower but the taller Leuojum aestivuum have continued the show; snowdrops are gone – just a few stray flowers on Galanthus ‘Lady Moore’ in a sheltered spot but daffodils are in profusion, some old varieties which have been years in the garden and some news ones to keep the interest going – one named ‘Chiva’ has multi-headed flowers and truly outstanding fragrance; magnolias are magnificent at the moment with M. soulangeana and M. stellata at their very best – they have escaped frosts this year though it is forecast for tonight; our native primroses are in full flower and their ornamental relatives are also in season; a number of pretty Primula x polyantha – a cross between our native primrose and the cowslip – are looking well in the garden with some different colours appearing also; Flowering currants are in full swing – I enjoy the smell from the foliage!; Erythroniums flower and vanish too quickly but they are so pretty and have such an attractive flower shape that they are worth growing; trilliums are terrific at the moment – I struggled with these for many years but now have a number which are thriving in the garden and it is still a thrill to have them growing well and flowering profusely; Snakeshead fritillaries are doing fabulously in our bulb lawn, they are obviously seeding about very generously and promise to be a feature in future years; what was expected to be an important old Irish daffodil – I received one bulb last autumn – opened today and was not what it should have been.. pffffffffff, there are often disappointments but tomorrow will have something else of interest; Arum creticum will surely open tomorrow and, maybe, the first of the yellow magnolias!

A lot happens in a few days in the garden!

Castlewellan Kindness

A little kindness can make a whole day great. We had wandered around the forest trail in Castlewellan Forest Park but a chance meeting with one of the gardeners changed a rambling, almost aimless, visit into an afternoon we enjoyed thoroughly.

This was our first visit to the Forest Park and we approached through the hilly countryside of south Co. Down to the town of Castlewellan with its spaciously wide main street, two squares and a very attractive Market House (built in 1764) which now houses the public library. It was an impressive approach with the entrance to the estate was directly from the town and I imagine it must the most wonderful amenity for those living locally and, given the number of people walking about, it seems that they take advantage of this and enjoy it.

There are several forest trails to choose from, some short; some long, and all pleasant

Our walk lead to this lake!

At one time the estate belonged to the Maginess family but has been in the Annesley family since 1741 and it was the Annesleys who engaged a French architect to design the layout of the town. The arboretum was begun in 1740 with trees from around the world. Castelwellan Forest Park in now in the hands of the Department of Agriculture and extends to approximately 450 hectares with most being managed as a commercial forest while also accommodating activities such as walking, cycling, horse-riding, orienteering, camping and caravanning. The walled “Annesley Garden” is at the heart of the arboretum which is considered one of the very best in the British Isles and contains the twenty oldest existing specimens in the British Isle, forty two champion trees of the British Isles and fifty champion trees of Ireland, a truly significant and impressive collection.

The “Peace Maze”, made from 6,000 yew plants, was planted in 2000 and 2001, mainly by volunteers, covers nearly three acres and has 2.18 miles of pathways. It was for several years the largest maze in the world and has become a huge attraction to visitors with quarter of a million in the first three years it opened.

Our visit to Northern Ireland was to visit friends rather than gardens and we hadn’t done our normal research into the garden before travelling. On arrival we simply studied the large map in the carpark and headed off on one of the several forest walks which were signposted. It was a pleasant walk – a little fresh air was welcome after the long drive – but held nothing of plant interest. We were at the end of the trail, with map in hand and considering the various signposts, when one of the gardeners came along on a small tractor. He stopped to say, “Hello” and to ask if he could be of help and our visit to Castlewellan suddenly surged from enjoyable and pleasant to being special. We chatted about gardening; that we knew one of the gardeners as we were fellow members of the Irish Garden Plant Society and that we were delighted to hear of the rediscovery in the garden of Narcissus ‘Countess of Annesley’, a late nineteenth century Irish daffodil cultivar which was presumed to be extinct. It turned out that we were talking to the man who had searched out and identified this historic daffodil, had transplanted numbers from other areas in the garden to a place of prominence which it would be admired and, most importantly, remembered. It was a hero moment – meeting somebody who had made a contribution to saving our heritage plants. For the moment, there is a restriction on the distribution of this daffodil as there had been an outbreak of fungal pathogen in the park which the bulbs, possibly, might spread to other gardens with devastating impact on trees – the forest park has cleared a hundred acres of trees to contain its spread.

Rather than continue our forest walk we were brought into the bothy area, formerly the accommodation of the gardener and also the works yard of the garden and on to the fabulously restored glasshouses which are on a raised area overlooking the walled garden – The Annesley Garden – which holds the treasures of the tree collection.

Scots Pine, Pinus sylvestris ‘Aurea’ dominated the garden and caught the eye on our visit as the sunshine made it glow. 

It strikes me as an unusual arrangement – a tree collection accommodated in a walled garden amid the formal layout of walkways, ponds and fountains – but it was a very pleasant setting and very enjoyable and, undoubtedly, there was an atmosphere one would not experience in parkland or woodland. It was a magical place, steeped in history, with trees which were truly impressive.

A Garden under Wraps!

Mount Stewart is one of the most beautiful gardens in Ireland and we make a point of visiting whenever we are close by but had never previously visited so early in the year. A visit in mid February was quite different to other times of the year – for unexpected reasons!

Mount Stewart, one of Ireland’s greatest gardens
The iconic yew harp in the Shamrock Garden

The garden is situated on the shores on Strangford Lough, on the Ards Peninsula, Co. Down in Northern Ireland and, while presently in the stewardship of the National Trust, the garden was the creation of Edith, Lady Londonderry. Her passion for bold and dramatic planting is continued to this day and the mild conditions of this seaside location allows tender plants to thrive – but not without some drawbacks at times of the year.

The formal garden beside the house was a strange sight with a myriad of plants which require protection from winter weather wrapped in layers of protective material so that the scene resembled an ensemble of monuments or statues but such, I suppose is the off-season of a garden which wishes to push the boundaries of what can be grown in our climate. However, after paying a ticket charge of £9.50 X 2 (€22), it was hardly the garden scene I had hoped to see and I wondered, given that sections of the garden were also closed for repairs to the lawns, if it would have been better to close the gardens altogether for a while.

Many plants wrapped for winter protection made for an unusual garden scene




Some of the ornaments around the garden also require winter protection.

However, as is the way in all great gardens, there was interest elsewhere and we continued our walk and found some more pleasant areas to enjoy.

Ice-cream first, then Weeds and Good Bits and Bad Bits – Ness Botanic Gardens!

As we approached the entrance to Ness Botanic Gardens information notices told us that we could enjoy two locally made varieties of ice-cream inside. I suppose we could have been told of worse things but I had come to see plants and a good garden and ice-cream was not of interest, especially as it was early in the morning. So early, that we had arrived a little before the garden’s opening time and, after browsing the shop for several minutes, we went to the plant sales area  which was open, though not for sales. It only added to our bad first impressions as the plants had, for the most part, dried out and the paving slabs of the footpaths were infested with weeds.

At times I can be quite negative in my view of gardens I visit. I become very annoyed with gardens where there a poor standard of maintenance, where weeds are widespread and where there is a general air of neglect. I don’t feel it unreasonable to visit a garden such as Ness Botanic Gardens and expect high standards of gardening, planting and maintenance and find it a huge disappointment when this is not what I experience.

There were many beautiful vistas in the Ness Botanic Gardens but also many areas which disappointed me. I’ll continue with photographs and captions.

Three very attractive vistas which are met very early in one’s walk around the gardens.

Immediately after the enjoyable views above we stopped at this bed of azaleas which was overrun with weeds. 

dsc_0027There were large areas of wildflower meadow which were pleasant, quiet and gave good views to the surrounding countryside. 


When there is widespread concern over the demise of our pollinating insects it is good to see an installation which provides nesting sites for bees. The one pictured above is for solitary bees – I had to wonder if solitary bees would feel at home in this high rise apartment block. Perhaps, they are not quite as demanding of their solitude as I am.  


This pond did not look well – of course, conditions may get ahead of the gardeners but seeing three ponds in this condition was off putting.  

This did not have the appearance of being left on the day we visited but seemed to have been there for some time.

The Rock Garden area is very attractive with mature specimens and comfortable walking pathways. The presence of Mare’s Tail throughout the area was a disappointment though. 

Is it unreasonable of me, when I spend £7.50 on admission, to expect a well-kept garden?

I realise that this is somewhat of a bearbug with me, this disappointment with gardens which charge admission yet do not maintain reasonable standards,  and that I am inclined to rant on about it but that’s how it is with me. Grumpy old man? Maybe! LOL!
