Vulvarium giganticum is a monumental perennial, endemic to the gardens of Crestignac. It is distinguished by its broad, thick, velvety foliage, which can reach a spread of nearly two metres in mature specimens.

Its particularly spectacular inflorescence generally appears in early autumn. It consists of a broad, fleshy spathe, ranging in colour from rosy cream to deep purple, surrounding an erect central spadix. In the oldest specimens, flowering may last several days.

Vulvarium giganticum favours humus-rich soils that remain moist yet are perfectly drained. It prefers partial shade and appears particularly sensitive to sudden changes in temperature and to draughts.

Growth is slow in the early years, then accelerates sharply as the plant approaches maturity. Once established, a specimen should be moved as little as possible.

Flowering remains difficult to predict. In some years, several inflorescences may appear in succession; in others, the plant remains entirely vegetative.

The gardeners of Crestignac report, however, that a prolonged period of calm may encourage flowering.

Local horticultural tradition attests to the presence of Vulvarium giganticum in the gardens of Crestignac for several generations.

The most serious botanists dispute its existence, which has so far had no observable effect on the plant.
