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.

Stephanandra tanakae a deciduous shrub with long arching growth. Native to Honshu Japan where it was seen growing on steep NE facing rocky cliffs at 920m. Here only attaining 1m x 1m in size. In our deeper, more fertile soil the plants are reaching 2m x 2m and producing a mass of small white flowers contained in terminal panicles. Ideally grow in full sun where the flowers are much more prolifically produced than in a shaded situation. Foliage a fresh mid green with a serrated edge.

The fashion to breed tighter more compact plants for modern gardens by passed this species from Japan. Hemerocallis exaltata is a vigorous herbaceous plant, the flower spikes reaching almost two metres in height. Showy, bright yellow trumpets are seen best with the sun on them. Certainly the clump planted in the garden border is visible from a distance away across the Oak Lawn.
A gentleman by the name of Arlow Stout (1876 – 1957) crossed many species and cultivars of Hemerocallis in the United States. An academic who understood the intricacies of pollination he became a prolific hybridiser and writer. Arlow worked at New York Botanical Garden from 1911 until 1948 where he also initiated a study to produce seedless grapes.

Styrax officinalis

Styrax officinalis

Styrax officinalis; a deciduous shrub with the most attractive white flowers. These are produced on the current season’s shoots. Initially a spherical creamy bud that on opening reveals a cluster of yellow anthers held on white filaments. Reference material mentions scented flowers; it is barely perceptible, even on a warm, still, humid day.
The ovate foliage is velvety to the touch and has a vague grey tomentose sheen to the reverse.

A native to southern Europe and the Middle East. Plants were observed growing in southern Anatolia, Turkey in field margins, cultivated areas and on steep slopes at 1098m. Our plants growing near the west gate have signs of winter tip dieback, but nothing detrimental to the plant which has put on good growth through this spring and into early summer.

Corylus ferox

Corylus ferox is a native to the Himalayas and NW China, found in association with Acer, Viburnum, Hippophae, Salix, spp. Seed was collected from a 6m x 5m deciduous tree in Sichuan Province where the parent plant was growing in a gravelly loam at 2410m on a NW facing mountainside. The multi stemmed plant growing in the copse is fruiting for the first time since grown from seed in 2005. A mass of spikes not dissimilar in looks to that of a Horse Chestnut carcass. However, these spikes are attached to both the nut and cup as protection and not as a complete shell casing. The colouring is intense red going creamy white as it matures.
