ACER palmatum 'Ueno yama'  This tree has outstanding spring colour, arguably better even than the similar 'Katsura'. The spring growth starts early and makes a bright orange splash of colour. Summer colour tones towards green before the oranges return again in the autumn. A vigorous and hardy tree which is upright when young, broadening with age. 4m.
	ACER palmatum 'Ukon' This has now been declared synonymous with Acer palmatum 'Aoyagi'
	ACER palmatum 'Umegae'  A lovely purple leaved palmatum, but with smaller leaves than usual. They are deeply divided and finely toothed, holding their colour well all summer before turning crimson in autumn. Slow growing and suitable for small gardens. Another Japanese cultivar to have notched up its century, but still be rare in cultivation. 2m See it in our Maple Glade
	ACER palmatum 'Uncle Ghost' Another gorgeous ghost! The lobes are so deeply divided, showing wonderful pinky apricot shades in spring before maturing to the characteristic boldly veined ghostly purple colours. Compared to the others in the group, growth is cascading rather than upright.  See it in our Maple Glade
	ACER palmatum 'Usu midori' This cultivar is very similar to 'Katsura', 'Mizuho beni' and 'Ueno yama' - bearing the same bright orange young growth. It is very poorly documented, both in literature and on the web, and I've not yet grown it for long enough to fully understand how it differs from these other similar cultivars. They are all so pretty though, it really doesn't matter which one you have - but every garden should benefit from this wonderful spring display!
	ACER palmatum 'Utsu semi'  The wonderful name translates to "Skin of a Grasshopper" It actually refers to a classic Japanese love poem and should therefore convey romance and happiness. The bold bright green leaves are almost leathery. The stunning autumn colours are purple to scarlet, dotted with orange. Forms a rounded tree like shrub. 2-3m
	ACER palmatum 'Villa Taranto'  A desirable plant named after the beautiful Italian garden of the same name. The linear leaves unfold orange-crimson, becoming orange-green almost immediately. Beautiful golden yellow autumn colour. Sturdy upright habit within an eventually more rounded silhouette. 2m See it in our Quarry Garden
	ACER palmatum 'Wabi bito'  A curious plant with a variety of different shape leaves which are green in summer before developing fabulous yellow autumn colour. Although rare, it is a very early cultivar, being first mentioned as early as 1710. 2m.
	ACER palmatum 'Waka momiji' A fabulous "coral bark" maple showing wonderful contrasting bright red stems in winter. For us, this is one of the more tolerant and well behaved of all the coral bark maples. Superb yellow to orange autumn colours. Vigorous when young and upright, yet free-branching, to 5m. See it in our Maple Glade
	ACER palmatum 'Wendy' I'm taken by this one too. The rather small leaves are particularly glossy and have been described as "ivy-like". Unfurling orange-pink, maturing to bronze red and finally deep green, it is most effective. Bushy, rather spreading habit.
	ACER palmatum 'Wetumpka Red' Selected in Alabama, so this one is tolerant of heat (once established). Dark red foliage has a brownish tinge as opposed to purple, giving it a slightly different colour. Scarlet autumn colour. 3m See it in our Maple Glade
	ACER palmatum 'Will's Devine' These reticulate, almost variegated, cultivars are so hard to describe, not helped by the degree to which they vary according to light and fertiliser levels! Deeply divided leaves are suffused with a brownish-mauve glow as they unfold, becoming more green with maturity, characterised by paler mid-lobes and very conspicuous veining. Of mounded, cascading habit so training a stem up a cane is the best way to gain height and structure. This one is quite unique and stands out for me in the winter too, by virtue of bright green bark that is lightly streaked with white striations. See it in our Maple Glade
	ACER palmatum 'Wilson's Pink Dwarf'  This distinctive plant is one of the best for very bright spring colour. The young growth emerges a bright, pale shrimp pink, before turning to green such that further new growth is highlighted against its changing background colour. Orange to red autumn colours. The leaves are tiny, often with defined and pointed lobes, particularly the central lobe. Unlike the 'Corallinum' group, this one's habit is sturdily upright making it ideal for a small garden or indeed to grow in a tub. However, as is typical of these brightly coloured maples, they can be very difficult and slow to establish, though once it does so, it has great potential to tolerate even our exposed site.
	ACER palmatum 'Winter Flame'  Simplest described as a dwarf form of the Coral Bark Maple, this is the answer for everyone with a small garden to whom I have said that 'Sango kaku' is too big. Also perfect for pots. The pinky orange bark in winter extends its period of interest to give truly year round beauty. Larger plants only this year. 1-2m The picture shows the early stages of autumn colour in a shady site. It's relative lack of vigour does mean that it isn't always the easiest to grow, so avoid extremes. See it in our Winter Garden

ACER palmatum 'Yasemin' A chance Dutch seedling between A. palmatum and A. shirasawanum, it is variably categorised under both species. Large shiny purple leaves are attractively toothed along their margins and hold their colour well through summer, even in low light, before developing lovely orange and red autumn colours. Potentially vigorous once it gets going.  See it in our Maple Glade
