Betula

Berberis x stenoplzyllag must take after B. empetrifolia, for it bears tio resemblance whatsoever to darwinii, the other parent. It is an elegant, graceful shrub with long arching branches wreathed in April with yellow, sweetly scented flowers. I give it plenty of room to expand its full charm, then tip the branches which adventure too far immediately the flowers fade.

First Betula platyphylla japonica, the ghostly Japanese White Birch, a fine specimen tree up to 40 ft. high. I trim away the lower branches so that the white stem can be seen to full advantage. I saw the Western Chinese form, B. platyphylla szechuanica for the first time over a 3-acre expanse of lawn, the wide sweeping branches a graceful crown to the white column of the bole.

In spite of this deficiency it is a superb shrub of compact habit. The yellow flowers in spring followed by the bright red berries, and deep scarlet of autumn colour make this species one of the choicest barberries. Where garden space is limited I would choose the variety atropurpurea. Used as a centrepiece in a blue and white ground planting, or as a contrast with deep orange annuals, it is charmingly effective.

Betula papyrifera is the Canoe Birch and it brings much the same effect to the garden as our own native birch. The varietal form from Alaska, kenaica, has a bark which glows a warm orange and this together with a rather upright habit makes it suitable for planting in a restricted space.

Berberis linearifolia has an almost tropical air and the gayest orange-red flowers imaginable. I have six plants in a rather exposed position, and they positively light up a cold April day when in full bloom.

With B. darwinii as one parent and B. linearifblia the other, what else could the offspring, lologensis, be but superb. The habit is erect and the evergreen leaves well formed, while the flowers are yellomi, softened with a hint of peach.
