This plant may be propagated without seeds, as it grows fast enough from slips; treatment the same as that of the Creeping Cereus, which see.

It takes its name of Stapelia from Stapel, a Dutchman, author of some botanical works, particularly a Description of Theophrastus’s plants.

This species has usually been called Convolvulus minor by gardeners, by way of distinguishing it from the Convolvulus purpureus, to which they have given the name of major.  It is a very pretty annual; a native of Spain, Portugal, and Sicily, and very commonly cultivated in gardens.

The most usual colours of its blossoms are blue, white, and yellow, whence its name of tricolor; but there is a variety of it with white, and another with striped blossoms.

The whole plant with us is in general hairy, hence it does not well accord with LINNAEUS’S description.  It is propagated by seeds, which should be sown on the flower-borders in the spring, where the plants are to remain:  they require no other care than to be thinned and weeded.

The Passion-Flower first introduced into this country was the incarnata of Linnaeus, a native of Virginia, and figured by Parkinson in his Paradisus Terrestris, who there styles it the surpassing delight of all flowers:  the present species, which, from its great beauty and superior hardiness, is now by far the most common, is of more modern introduction; and, though a native of the Brasils, seldom suffers from the severity of our climate; flowering plentifully during most of the summer months, if trained to a wall with a southern aspect, and, in such situations, frequently producing ripe fruit, of the size and form of a large olive, of a pale orange colour.
