Six species. Hardy deciduous shrubs. Ripe Cuttings. Common soil. The species most common in our gardens is H. hortensis. To obtain of this very large flowers on a very small stem, strike cuttings; do not let them branch: grow them in rich soil, and bloom them the following season.

"To get large bushes of hydrangeas in the open air, plant them in good rich soil; form a basin of clay all round them, six inches deep, and in dry weather fill it with water every evening, after they have got fairly into leaf. Towards autumn withhold watering altogether. Get their wood ripe. For winter, stuff straw between their branches, wrap them well in it, and mat them up." - Gard. Chron.
