December, January,
February

Clump-forming Form

18 x 30
(45 x 75)

Strap-shaped, wide,
Dark Green

It is not suitable as a garden plant except in rockeries. They are best grown in containers in a well drained, slightly acid sandy mix and appear happiest if pot bound. They seem to grow best in shallow containers and will flower regularly if fed with a slow release fertiliser.

The African Lily Contrasts well with yellow flowers. Easily combined with Kniphofia, Crocosmia, Phygelius, Potentilla and Iris.

Plants were grown in containers in con-servatories and flowered in Europe in the late seventeenth century.

Agapanthus
albus

Clump-forming Form

30 x 18
(75 x 45)

Narrow, strap-shaped
Mid-Green

White Lily of the Nile is ideal for that hot sunny spot in the garden. They tend to flower better if the roots are slightly restricted, so ideal for growing in pots and bringing inside for the winter months. If growing in the border provide a good winter mulch to protect them, and they do need very well drained soil to stop them rotting.

Compact clumps of strap-shaped leaves above which the white flowers rise as rounded umbels on tall stems. Excellent as cut flowers. Keep well-watered during the growing season, applying a balanced liquid fertiliser each month from spring until the plant flowers. Over-winter container-grown specimens in a sheltered spot.

Alchemilla

Yellow-Green

Mat-forming

4 x 20
(9 x 50)

Deep Green -
underneath is silver

One of the things that make Alchemilla so interesting to plant scientists is that many are able to produce seed without the need for fertilisation of the flowers; this is known as apomixis. There are very few plants that are like this. It means that the seeds are genetically identical to the parent plant. This is useful on a practical level for gardeners because any seedlings that arise in the garden will be exactly the same as the parent.

The main collection of Alchemilla can be found close to the Limestone Rock Garden at the western end of the Main Lawn. They are at their best in late spring from mid-April through to June as the fresh green foliage unfolds and water droplets collect on the foliage." from Botanic Garden of Cambridge University.

(60 x 75)

Apple-Green, fan-shaped leaves, up to 3 inches in diameter, 9-11-lobed with short incisions, densely hairy

The plant is often grown as a ground cover, and is especially valued for the leaves in wet weather, as the water beads and sparkles on the leaves.

Alchemillas are one of our most familiar garden plants through the widespread cultivation of Alchemilla mollis, Lady’s Mantle, a stalwart of herbaceous borders and cottage gardens, the froth and foam of its acid green flowers acting as an elegant foil to almost anything it surrounds. The genus Alchemilla is however much more diverse comprising over 300 species of clump-forming, herbaceous perennials with kidney-shaped, lobed leaves and greenish-yellow flowers.

Japanese Anemone can be invasive or weedy in some areas, throwing out suckers from the fibrous rootstock, to rapidly colonise an area. Once established they can be extremely difficult to eradicate. On the other hand, they can take some time to become established.

Try rich red and purple hardy fuchsias, such as 'Mrs Popple' and 'Brutus'. Hydrangeas work well in a simple planting scheme and the long-flowering, blue Geranium Rozanne is wonderful partner to both pink and white forms.

The Alpine Garden Society Encyclopedia of Alpines Volume One (A-K) (ISBN 0-900048-61-1) and Volume Two (L-Z) (ISBN 0-900048-62-X) superceeds The English Rock Garden (1919) by Reginald Farrer and its supplement The Present Day Rock Garden (1937) by Sampson Clay.

The above encyclopedias by the Alpine Garden Society describe 1000 genera of all alpine plants in cultivation, as well as many found in the wild but not yet in cultivation. All have rock garden or alpine house potential and the larger plants can be used in herbaceous borders. From page Viii of Volume One:-
"What is an alpine plant? Technically and from a botanical perspective alpine plants are those which grow above the tree line in mountain regions of the world in what are called subalpine and alpine zones; this includes species found at low altitudes in severe climates devoid of trees such as the Arctic and Antarctic. From a horticultural point of view, however, this definition is extended to include many other small flowering plants and ferns from low altitudes, whether from the seashore, marsh or woodland. 'Alpine' and 'rock garden' are frequently used to encompass this wide spectrum of different plants. In reality any small plant suitable for growing on the rock garden, scree, raised bed or in a trough in the open garden, as well as a great range of others more easily grown within the confines of an unheated glasshouse or cold frame, are included here within the definition of 'alpine'.

By general agreement, rock and alpine plants are thought to be small, often with a hummock, mat or tufted habit and often less than 12-15 inches (30-38 cms) tall. However, anyone who has visited a mountain region will know that not all the plants seen there necessarily fit into this handy definition; larger perennials and shrubs may sometimes be seen cheek by jowl with the hummocks and mats. A visit into any large rock garden, such as those of the well known botanic gardens at Kew and Edinburgh reveals a similar mixture and it is this larger concept that is used here. In general 24 inches (60 cms) in height and 39 inches (98 cms) spread has been taken as the maximum, but at the same time some potentially larger plants are included, for example the large yellow gentian found in the Alps and Pyrenees, Gentiana lutea, or the stately giant rhubarb of the Himalaya, Rheum nobile; both large plants but indisputably alpine."

Why the sight of flowers from 1 in 4 permanent herbaceous perennials in this border is not available

The variety of plants that can be used in alpine gardening is obviously very large and very bewildering at first approach. With a view to easing the task of selection here are lists of alpines most likely to thrive and flourish under certain easily defined conditions and for special purposes, with
Alpines and Paving.

The standard potting and seed-soil recipes from The Propagation of Alpines by Lawrence D. Hills are at the bottom of the page on Alpine - Sink and Trough Gardens.

To compare

Phlox paniculata 'Nesperis'

Dear Mr C H Garnons-Williams,   
Thank you for your enquiry to the Royal Horticultural Society's Members' Advisory Service. 
On investigation, I have concluded that the phlox labelled as 'Nesperis' in the garden is in fact: Phlox x arendsii 'Hesperis' . 
A search on the internet will generate a great deal of information on this cultivar.
I hope this information is helpful.
Yours sincerely,   

Tony Dickerson
Horticultural Advisor
