Weigela decora collected in Japan from an area of dense mixed forest containing Cryptomeria japonica and Stachyurus praecox, these were huge parent plants spreading and reaching 4m x 4m. Here a huge bulk of deciduous woody shoots and twigs forming, an ideal ecological habitat for woodland life. Flowering just now, the peduncles opening a creamy yellow then the pinks and red shades start to appear, giving an unusual floral display.

You study diligently, you consult books, you visit other gardens for ideas on colour and combination then a rampaging Ranunculus invades your border and the most appealing floral combination is created. The herbaceous Geranium macrorrhizum ‘Album’ has become intertwined with Ranunculus repens, the Creeping Buttercup to great effect.

The Genus is just the start. As plants are collected in the field they arrive back at the Botanics with collectors notes; some detailed, some not so. These Roses were collected a seed in China. The parent plants were growing on the edge of mixed tree and shrub woodland between 2000 and 3000 meters. Associated vegetation was Rhododendron, Acer, and Sambucus with ground flora, Anaphalis, Rumex, Plantago, and Polygonatum. Having grown on the seed to planting out stage we then it to flower. A specimen is then taken to the Herbarium for verification. Once this is completed the entry in BG-BASETM (the gardens plant data base) is updated and the label engraved.

Below just are some of the species roses in flower in the Chinese Hill Side.

The sun filled days we have been experiencing have brought out the flowers on Helianthemum nummularium ssp. tomentosum to perfection. This subspecies is native to Italy, collected on the west coast of Sicily. The mat forming habitat is ideal for colonising the concrete pad it is growing over. Here the plant absorbs retained heat from the sun to the benefit of a profusion of single golden yellow flowers awash over the evergreen foliage.

Erinacea anthyllis
Erinacea anthyllis

Erinacea anthyllis

Erinaceae anthyllis grows in mountainous regions of Europe and North Africa. A hugging evergreen with sharp spines to protect from grazing animals. The blue tinged purple flowers cover the plant at this time of the year. Look out for it tumbling over the alpine wall where it has an open deep rooting substrate. This drained, dry medium prevents waterlogging around the base of the plant resulting in longevity.

The herbaceous Peonies; short lived in bloom but once established in the border are you callous enough to dig them out? This cultivar, Paeonia ‘Rose Garland’ dates from the 1940’s, benefitting from a few pea sticks to hold the top heavy growth in place. It repays the gardener and florist with colour from bud swell stage, when they are ideal for cutting to place in a vase, to petal drop. Left in place the seed pods ripen and split open adding interest later in the season.

Heuchera 'Firebird'

Heuchera ‘Firebird’

May, a month of long weekends and long warm evenings; only partially true this year.

The low temperature throughout May has not been conducive to growth. The student plots are at least two weeks behind in growth compared to previous years. Fleece coverings have helped where seedlings and young plants have been transplanted. The exception is the rows of Broad Beans, especially the red flowered cultivar ‘Crimson Flowered’ which is attracting much attention from visitors.

It is the recently planted bedding Geraniums, or Zonal Pelargoniums as they are referred to, that have suffered from the unseasonably cool weather we experienced through the month of May.
As the attached image shows there is a visible purpling to the leaves in all the plants set out in the Palm House border. Compare this with the image of the Geraniums remaining in the cold glasshouse. It illustrates the importance of hardening off prior to planting out allowing the plants to acclimatise to an outdoor situation. These plants, although going through the hardening off process were not prepared for such prolonged low temperatures. June is not starting well with gales from the west.

The real star this week is Heuchera ‘Firebird’. An herbaceous plant that has produced a mass of flower spikes covered in bright red flowers. Planted as a drift to the north of the herbarium, they have lifted this dreary area with their colour.

Mass planting of the white form of Digitalis purpurea are attracting much attention in the woodland garden. These selected seedlings are sown and grown for one year, transplanted and flower during their second growing season. The flower spikes reach two metres and are covered in white flowers that en mass have the presence to draw the eye from 100 metres distance and more. Once in about them appreciate the humming of bees moving through to extract pollen and nectar from the pendulous tubular flowers.

Enkianthus campanulatus

This season the Enkianthus campanulatus have flowered prolifically. This, a result of a long warm spring preceded by a hot dry summer ripening the wood. The show does not end with the falling of the flowers; the soil around the base of the deciduous multi stemmed shrub is layered in creamy white pearls, the fallen fused petals that make up the corolla. A native to Japan, now a firm addition to woodland gardens throughout Britain.

Maianthemum racemosum

Take a moment to visually absorb the shades of green on the immature flower buds of Maianthemum racemosum. Growing on the edge of the woodland garden it is another member of the Ruscaceae family, native to North America.
Just about reaching 1 metre in height this herbaceous clump produces upright stems covered in alternate leaves with a terminal panicle of fragrant flowers.
