When you see a magnolia in the North blossoming before the leaves, you may be sure it is an exotic species, and if the flowers are colored you may be equally sure that it is a hybrid between two oriental species, and belongs to the group of which the type is _M. Soulangeana_. The owner may be a magnolia enthusiast, able to show you on his premises both parents of this interesting and beautiful hybrid.

The Yulan magnolia, for centuries a favorite in Japanese gardens, covers itself before the leaves appear with pure white, fragrant flowers, bell-shaped and fully six inches across. In our Eastern gardens it is quite as much at home, and though young trees are oftenest seen, the older specimens are as large as any native magnolia. This is one parent. The other is but a shrub, the purple magnolia, _M. obovata_, that must be protected against the rigors of our Northern winters. It blooms in May or June, and its purple flowers, with rosy linings, are relatively small and almost scentless. The children of this parentage get their tints of pink and rose and crimson from this purple magnolia shrub.

Splendid, hardy, fragrant, big-flowered varieties have arisen from this cross. All are small trees, suitable for planting in city yards, where they are decorative throughout the season.

The starry magnolia blooms in March or April, covering itself with star-shaped white flowers made of strap-like petals that form a flat whorl instead of a cup. This is the earliest magnolia and wonderfully precocious, blooming when scarcely two feet high.

The Southern states can grow the splendid Campbell's magnolia, which is in its glory in the high mountain valleys of the Himalayas, where it reaches one hundred feet in height. The fragrant flower-cups, from six to ten inches in diameter, shade from pink to crimson. It is rare in cultivation because it is not easy to grow, and northern horticulturists fail utterly to grow it outdoors; but the fact that it is the most beautiful of all exotic species must encourage its culture in the South, and difficulties will be overcome when the tree's peculiar needs are fully understood.
