Passion-Flower. It derives its name from the idea that all the instruments of Christ's pas-ion are represented in it. Most of the passion-flowers are natives of the hottest part of America. The rose-coloured passion-flower is a native of Virginia, and is the species which was first known in Europe. It has since been, in a great measure, superseded by the blue passion-flower, which is hardy enough to flower in the open air, and makes an elegant tapestry for an unsightly wall. The leaves of this, in the autumn, are of the most brilliant crimson; and, when the sun is shining upon them, they seem to transport one to the gardens of fairy-land.
