Guest slot- Favourite plants

We are not precious at Cool Gardens, and are delighted to work with a range of top designers as well as our own . Stephen A Ryan worked with us during the early part of this year and we discussed our favourite plants- I asked him to pull it together into a blog to share and here it is. This is the first of a group as I have asked each of our designers to do the same!

FAVOURITE PLANTS BLOG 1-Stephens Favourites

“Inside the world of garden design there are many fashionable planting trends that designers focus on and at the moment two of the most talked about ignore shrubs completely they are ‘New Perennial’ planting lead by the work of Piet Oudorf and meadow planting seed mixes and I have to admit that they both sometimes leave me a bit cold.

For the vast majority of clients a good planting scheme that works all year round is normally quite a diverse and complex collection of plants and I feel that shrubs are an integral part of them. When I last visited the Cool Gardens barn, Ruth and I started chatting about our favourite shrubs and I decided to put some of my favourite ones down on paper, so here they are. I would also love to hear of your favourites be they winter flowering, summer flowering, evergreen, fragrant or whatever takes your fancy! Stephen A Ryan

Viburnum "Eve Price"

A very useful winter-flowering evergreen shrub with heads of pinkish-white flowers, opening from pink buds from December to April, followed by dark blue fruit. This popular form is denser and more compact than others and thrives in sun or shade, the shiny, dark green foliage providing an excellent evergreen backdrop for ornamental and feature plants.

Viburnum × bodnantense ‘Dawn

Not evergreen but the dense clusters of fragrant, dark pink flowers on bare stems from November to March are amazing and dark green leaves then follow.

They also last a long time if  you cut the flowers for a display in the house.

Hedge moving….

Carl spent the day moving a few small plants in St Johns Wood..

These 2.4m rootball yew trees were delivered first thing and the team spent the rest of the day manhandling them through a busy building site to the rear garden- thanks to all who helped. Instant hedging is indeed possible!

Hedging and tree time approaches!

Its the time of year when rootball stock comes intot he nurseries and hedging and larger tree planting is the order of the day.

Plants are largely dormant and field grown stock can be lifted, roots are wrapped in hessian and can be transported and planted at much lower cost than containerised plants. The picture above was a full container load of 4m Photinias that we planted a few years ago in Potters bar, more commonly we are asked for laurel hedging and screening, yew hedging (this is the only time of year to get really good big yew), and even box hedging which we can get at a range of sizes from 40cm, but much more bushy and mature than the normal pot grown specimens.

We recently checked and we know that we can deliver most options to site for you at lower prices that we could find on the web, and obviously our lovely maintenance team will be happy to quote you for removal of old hedging, mulching, and planting of the new stock!

 

3 top plants for the spring…

At this time of year I am looking out for the first signs of the winter aconite (eranthis hyemalis). Plant in autumn for a heart-lifting breath of spring. Whilst it is too late to plant for this year- it is worth making a note to do so later. Shrubs can be planted now so my suggestions are below…

Shrubby honeysuckle (Lonicera fragrantissima) adds a welcome whiff of scent as well as pretty flowers

Perhaps my favourite shrub in the spring is the delightful Viburnum carlesii with balls of scented flowers that the long tailed tits in particular seem to enjoy..
