Baking in the heat on a raised terrace with flower spikes hitting two plus metres in height this Watsonia x longifolia is an elegant sight. It can be seen growing in the confines of the alpine area from where Elspeth promises to select a suitable planting site in the Garden and with due care and attention move the corms during the winter. Disliking disturbance it may then take a year or two to settle before annually producing tall flowering spikes of pink petalled flowers.

Helichrysum aucheri

Helichrysum aucheri

Helichrysum aucheri is in flower on the scree. Papery flower heads on 150mm stems. Collected in Turkey but native to greater Arabia. Grown in well drained soil and loving direct baking hot sun thus ensuring regular flowering. The silvery sheen on the foliage is sadly not at its best this year due to the continual torrential downpours we have experienced.

Cacalia aff. delphiniifolia

Cacalia aff. delphiniifolia

A collection from China is growing opposite the pond lawn. Cacalia aff. delphiniifolia (aff. means ‘akin to’ used in plant nomenclature) loves an area of bare soil within a woodland fringe. However, take a look at the red tinged arching shoots that are sent out from the parent plant. This is a strong growing, colonising herbaceous perennial. If you choose to plant it, then an annual clearance from the bases of shrubs and root zones of other herbaceous material is essential otherwise expect domination. Attractive foliage in the shape of divided leaves. The terminal flower spike is multi-budded, opening white. Needing good light to flower, those plants on the edge of the border producing strong stalks. As the shade deepens, little or no sign of flower spikes.

Looking for a splash of colour in the border? Trollius chinensis ‘Gold Queen’ could be the plant you are looking for. An herbaceous perennial growing to a height of 1.3m. The terminal cup shaped bright orange sepals surround the narrow mass of petals, a floral extravaganza. Also in flower is Ligustrum delavayanum, producing panicles of miniature, white, highly scented flowers. This multibranched evergreen “Privet” is found growing through Asia. Flowering as a timely reminder that when walking around suburbia the yet to be cut Privet hedges will also be full of pollinating insects making the most of these flowers. On warm still days the scent fills the gardens and pavements about them. One good reason to put off the inevitable and enjoy Wimbledon.

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 Azalea collection is blooming. One of the best on the bank is Rhododendron luteum, reliable to flower, full of mid yellow blooms and the scent drifting through the lawn. These plants grow through S.E. Europe, Turkey and the Caucasus. Strong growing, deciduous, much branching shrubs. The flowers are followed by elongated seed capsules full of seed, much of which may be viable and can subsequently lead to self-seeding.
