About
Arisaema silvestrii is a bulbous cultivar within the Arisaema genus, known for its columnar upright habit and deciduous foliage. Like other Arisaema, it produces distinctive tubular, hooded spathes enclosing small flowers on a spadix, followed by a spike of red berries. This cultivar thrives in partial shade with a north, east, or west-facing aspect, preferring moist but well-drained loam or sandy soils that are acid to neutral in pH. Hardy to UK zone H3, it suits sheltered positions and is ideal for cottage gardens, flower borders, and underplanting beneath roses and shrubs, with spring as its season of interest.
