Passiflora
PASSIFLORA CAERULEA.--Passion Flower. Brazil and Peru, 1699. Though not
perfectly hardy, yet this handsome climbing plant, if cut down to the
ground, usually shoots up freely again in the spring. The flowers, which
are produced very freely, but particularly in maritime districts, vary
from white to blue, and the prettily-fringed corona and centre of the
flower render the whole peculiarly interesting and beautiful. P.
caerulea Constance Elliott has greenish-white flowers; and P. caerulea
Colvillei has white sepals and a blue fringe. The latter is of more
robust growth, and more floriferous than the species.
