Plant of the Month: Camellia (March 2025)

During March, when the changeable weather still surprises us, it is wonderful to see the Camellias in flower, as they provide the much-needed WOW factor during the colder days – their profusion of flowers, colours, shapes and patterns add an immediate vibrancy and character to any garden or parkland.

In my neighbour Linda B’s garden, there are three Camellias but one stands out. The flowers are smaller and single, white (blush-pink as they age), scented and beautiful. The leaves are also different: matt-green and elongated and the overall appearance of the shrub is more elegant. It has grown, albeit slowly, and is now approximately 2’ in height. A plant app identifies it as possibly Camellia sasanqua.

Plant of the Month: Galanthus (February 2025)

If you wish to see the snowdrops now, I can highly recommend the Royal Botanic Gardens Kew. The gardens are easy to reach via the District Line to Kew Station. The woodland garden (near the Princess Diana Conservatory) has meandering paths beneath the trees, where an array of snowdrops, aconites, hellebores and mauve-coloured crocuses (the shade of colour I’ve only ever seen at Kew) are displayed to a wonderful effect. Visiting on a beautiful sunny day makes the gardens appear even more delightful.

The magnificent sandstone rock garden nearby, which mimics mountainous regions, is an important feature of the gardens, and here and there, in mostly sunny locations, could be found very choice, small clumps of snowdrops which are labelled for the visitor. I would love to have any of these growing in my garden and I thought you might too.

Galanthus ‘John Gray’: This early-flowering snowdrop is regarded as very choice indeed, which was seemingly found in the Suffolk garden of the late John Gray. I was captivated by the shades of lime-green on the inner segments.

Plant of the Month: Daphne (January 2025)

In the bleak midwinter, in amongst the primroses and snowdrops, the New Year brings excitement as the Daphne shrubs come into flower. For one member, several are looking looking extremely handsome and are, at present, the highlights in her garden.

Daphne odora ‘Perfume Princess’: This evergreen to semi-evergreen variety was bred in New Zealand and is considered the most perfumed of all the Daphnes. Between January and March, this shrub, which is regarded as hardy (although it suffered from the recent heavy frosts) will send out pale-pink blooms amongst its upright, handsome foliage, reaching a height of 1-1.5m over the years. Our CABAHS member says it has “wonderful scent and made a showy plant in just a few years.” I note that there is also a variety Daphne ‘Perfume Princess’ White on the market that would be a bonus to any garden.

Plant of the Month: Clematis cirrhosa ‘Freckles’ (December 2024)

One of the joys of walking around the neighbourhood is noticing what’s growing in front gardens and I like to stop and admire the imaginatively designed Xmas wreaths on doors at this time of year, planted window boxes and containers, and see what else is flowering in residents’ borders. And, when at bus stops, I have more time to absorb what’s around me.

So, at a bus stop a few days ago I noticed Clematis ‘Freckles’ cascading over the wall of CABAHS member Linda W’s garden.

Linda tells me that she bought the clematis six years ago at around this time of the year – with its grey, dank days – “when one needs cheering up and it has not disappointed.” Linda also says that although the vine was slow to establish when planted on the cooler side of the property, it has really taken off. It was planted with a honeysuckle and it flowers profusely in the south/south-west boundary wall. In the summer months it can soak up the sun and in the winter is sheltered by the brick boundary wall.

Plants of the Month: Westringia fruticosa and Salvia guaranitica ‘Black and Blue’ (November 2024)

Although I have written about both these plants in the past, I have chosen them again as ‘Plants of the Month’ because the flower colouring of each is in harmony with one another and both brighten up a garden during the long winter months.

Westringia fruticosa (Coastal/Australian Rosemary): This is second plant I have grown of this variety over the years: the first, given to me as a rooted cutting, had a good branch structure and lasted several years in a pot, positioned on a south-facing table; the second was purchased this June from a specialist nursery at the Horniman Plant Fair and, once again, it has an attractive rounded shape, which means they are suitable for growing in pots whilst they are small.

Plants of the Month: Salvia (October 2024)

Salvia ‘Amistad’, in less than 20 years, has become a much-loved cultivar throughout the world. and is known as the ‘friendship sage’. It was discovered in a tray of salvias at a plant sale in Argentina in 2005 by Dr Rolando Uria, and he decided to name it ‘Amistad’, meaning ‘friendship’ in Spanish.

There is much to love about this plant, in that its 1.5m high, bushy, rounded habit is ideal for planting schemes, guaranteeing a display of purple flower spires, with highly aromatic foliage, from mid-summer until the frosts in October-November. It’s not 100% hardy, so I have lost it a couple of times over the years but it’s always worth repurchasing. The young growths are adored by slugs and snails, so during wet weather in spring it can be difficult to get going.

I have noticed, however, that in London’s parks, Salvia ‘Amistad’ really thrives and can be seen growing happily and well-established in May, beneath London Planes in much drier soils, where the mature trees are protecting the plants during the winter months. And the drier soils obviously do not attract the slugs during early spring growth.

Plant of the Month: Clematis (September 2024)

What a struggle it has been to protect the shoots of these two clematis from sustained attacks by the usual culprits this year! Not only did I use a garlic spray (one clove of garlic simmered in water) but I also liberally (and continually) sprinkled spent coffee grounds around the base of the plants. Although they were saved, I did lose other clematis: scented C ‘Betty Corning’, C ‘Rising Star’ and C ‘Wedding Day’ – all absolutely lovely and such a loss that I will need to repurchase them.

Clematis ‘Princess Diana’
This clematis is definitely one of my ‘top five’. The tulip-shaped flower is an unusual shade of bright pink, with beautifully striped markings both inside and outside of the petals (sepals). This variety (texensis) was introduced by a British breeder to honour the Princess of Wales in 1984 and has deservedly been given the RHS Award of Garden Merit.

As to be expected ‘Princess Diana’ came into flower late – in July, rather than June – and has been flowering continually, with eight flowers and a few buds on the vine at present.

Plant of the Month: Agapanthus (August 2024)

One of the nicest aspects about walking around the streets in our neighbourhoods is being able to view the diverse range of flowering trees, shrubs, perennials and bulbs that enhance front gardens and, in early August, it’s the showiness of Agapanthus that makes one stop in one’s tracks in admiration.

And so, it was an added pleasure to be able to admire the magnificent evergreen Agapanthus praecox “Madeira Blue” and “Madeira White” in my neighbour’s rear garden. Linda tells me she purchased the bulbs in Madeira approximately ten years ago, where these perennials have become naturalised throughout the island.

The plants are extremely tall and vigorous and absolutely stunning, with additional flowering stems this year, having outgrown (and broken) previous terracotta pots. The bulbs have been in the existing plastic pots (sitting on feet) for the past three years, having been divided up – no easy task – and planted into several more containers. They have not been fed for a while and are not given protection in the winter (it’s a sheltered garden) with the flower heads left on until spring.

Plant of the Month: Dierama pulcherrimum (July 2024)

We might complain about all the rain we have had over the last few months but the plants have just loved, loved, loved it!

So, for the first time ever, I can celebrate, as my Angel’s Fishing Rod (beautiful name) is due to send up at least four flowering stems after many years and I put this down to the extensive rain we have endured this past winter and spring.

At Sissinghurst Gardens recently, I spotted two Dieramas in flower – the maturer pink-flowering specimen in the sheltered Rose garden, in a front-of-border, corner position where two paths meet, and a smaller, delicate-blush-mauve-flowering specimen growing in a south-facing border, situated in front of a tall brick wall – both looking absolutely gorgeous.

Plant of the Month: Rose (June 2024)

June really is the month for roses and when I saw Margaret T’s roses growing on her allotment, I was enchanted by each and every one and I have listed below a few that are in flower now.

Rosa 'James Galway' — Rosa ‘James Galway’

A David Austin climbing rose, introduced in the year 2000 and named after the Irish flautist. Margaret grows this rose as a shrub, so the flowers are at head height and the pink blooms, paler at the edges, have an old rose appearance and fragrance.

Rosa 'A Whiter Shade of Pale' — Rosa ‘A Whiter Shade of Pale’

What a name! And, what a rose! This gorgeous hybrid tea has blush-pink, very fragrant, repeat-flowering clusters, and glossy dark-green leaves. Considered disease resistant. Introduced in 2006 by rose-breeder, Colin Pearce.
