• Packaging suited to live plants

Argyreia nervosa belongs to the Convolvulaceae, the bindweed and sweet potato family. It is a vigorous climber, able to cover a large area in a single season in good conditions.

Its heart-shaped leaves can exceed 25 cm. The upper side is bright green, the underside covered in a silky white felt that catches the light: this is where the name argyreia comes from, from argyros, Greek for silver. The flowers are large funnel-shaped corollas, mauve to purple, with a darker throat, typical of the family.

It is a tropical plant, and it does not forgive frost. In our climate, grow it in a pot, to be brought in before the first cold spells, or in a greenhouse.

It wants warmth, plenty of light, a rich, free-draining substrate and a sturdy support: the climber becomes heavy. Water regularly during growth, much less in winter. Its vigour is its main characteristic: allow plenty of space or prune.

Why are the undersides of the leaves silver?
They are covered in a down of very dense white hairs. This is a common adaptation in plants exposed to strong sunlight, and here it is the main ornamental appeal of the species.

Is it frost-hardy?
No, not at all. It must be overwintered frost-free, in a conservatory, greenhouse or bright indoor spot.

Does it grow fast?
Very. In the growing season, with warmth and light, growth is spectacular. Provide a stake or structure from planting.

Can it be grown indoors all year round?
Yes, in front of a very bright window, but it will stay more compact and will rarely flower. Flowering requires plenty of light and warmth.

This plant is sold exclusively as an ornamental and botanical collector's plant. Also worth exploring: our rare plants and our folklore plants.
