The Cobaea is a rampant-growing soft-wooded climber with bell-shaped flowers, thriving well in any good soil but preferring a sheltered, sunny situation.

Propagate by seeds sown, in February, one-eighth of an inch deep in a hotbed, and potted off in three-inch pots. As soon as the young plants have filled the pots with roots, gradually harden them by placing the pots in a cold frame; in May, plant them out where they are to remain.
