Growing on the tufa scree with roots into a well-drained substrate is Chaenorhinum origanifolium. This perennial from Southern Europe is flowering well into autumn from a summer start. The clumps of trailing shoots are covered in small purple, white marked, flowers.

The corolla has the typical open mouth of the Toadflax and Snapdragons, all in the family Scrophulariaceae. Or as we should now call it: Plantaginaceae when following the Angiosperm Phylogeny Group III (APG) system of classification.

The Clematis akebioides growing at the east gate lodge is covered in flower. The buds are held on long stalks setting the flower out from the straggly stems. Opening slightly yellow they turn a burnished brown complimenting the other autumnal colours in the garden. Collected in Yunnan province, SW China where it scrambles through shrubs reaching 3 metres in height. Deciduous foliage covers the untidy mass of tangled stems that work their way into and through any plant or supporting structure to aid support.

This week sees a second member of the genus Tricyrtis in flower. T. formosana, this species standing tall and making a show in the peat walls. A profusion of mottled purple flowers, which as the tepals drop leave the stigma prominent above the immature triangular seed pod. Growing to 1 metre plus and the thin stems supporting flowers and foliage. A native too Taiwan, it was seen growing at 2650m in a shady bank at the edge of degraded open woodland of Pinus taiwaniana.

Tricyrtis macrantha has the largest flowers of the genus; pendulous yellow tepals are stunning when shown well against the foliage. It is the inner corolla that adds interest, covered with brown freckles. The internal flower parts are robust and cling together with a crystal icing topping. Ideally planted to cascade over a wall or rock to allow the pendulous growth to be shown to full advantage. Native to Japan.

Sorbus microphylla

Sorbus microphylla

The specimen of Sorbus microphylla agg fruiting profusely in the copse was collected in the Langtang National Park area of Nepal. This is the area devastated by the May 2015 earthquake. It is likely that the parent plant has been destroyed by the weight of tumbling rocks and debris. Take a walk to the copse area of the Garden and appreciate this slightly built tree growing and fruiting.

With deciduous leaves colouring and dormancy on its way, now is the time to consider tree planting. Take due account of the weather. Depending on the size of your garden choose a tree that will not dominate and overpower the gardenscape. Pictured is Betula ermanii, a deciduous Birch from Japan. Here it has made good growth and the trunk, after ten years of growth, has characteristic peeling, flaking white bark. So, a choice, fruit or forest. Many of the edible Pear cultivars also provide good yellow colour in autumn. With the added benefit of a crop of fruit. Fruit can be grafted onto a well formed rootstock of suitable vigour to suit your garden or allotment plot.

Planted at the entrance to the John Hope Gateway is Rosa hirtula. A native to Japan where it is found growing in association with, amongst others, Larix kaempferi, Cornus controversa, Juglans ailanthifolia and Acer japonica. This year the plants have a good crop of fruit, green at present, ripening brown. The dumpy, squat hips are covered in a mass of spines with a wide, flattened calyx end.  The plant itself has vicious upward facing spines on the purple coloured shoots. Growing to two metres with finely cut foliage which takes on yellow tints at this time of year.

Colour this autumn has been unrivalled. The warmth from the sun and the dry season have combined to extend the floral season. Take a last walk through the student plots within the demonstration garden. The fresh intake of horticulture students are on the cusp of grubbing everything out to prepare their plots for fresh sowings. Absorb the scent drifting off the Alyssum, a mass of white flowers. Marvel at the tall Cosmos that have not blown apart this year. The Sweet Pea towers still have pickings that would fill vases in the home, albeit with shorter stems. The real stars are two cultivars of Rudbeckia hirta, short lived tender perennials that are best treated as half hardy annuals; sowing, growing, flowering and composting each year. R. ‘Irish Spring’, with yellow petals and a green centre, the heavy morning dew settles on the foliage magnifying the leaf hairs. R. ‘Aries’ with a brown centre and markings radiating out on the petals.

With the protection of the alpine house this pan of Scilla lingulata var. ciliolata sunk into the sand bed is flowering exceptionally well. An added bonus is the scent I associate with the mass of spring flowering bulbs grown here.

Weeding through the border carefully, and before a size 10 tackety boot crushed it, eagle eyed, we spotted a seedling of the Monkey Puzzle tree, Araucaria araucana.
An unexpected find, a healthy dark green colour with the tell-tale spikes to the end of the leaves.
The two mature trees in the garden to the south of the Front Range Glasshouses, one male; one female tree are producing fertile seed. The squirrels are breaking up the dome shaped cones and dispersing and burying the seed they do not eat.

A native to the Andean mountains of southern Chile and Argentina where they grow on the slopes of volcanoes. Seed was first introduced to Britain in 1795 by Archibald Menzies, a plant collector from RBGE.
