Selenicereus grandiflorus is part of the Cactaceae family and is native to Mexico. It is epiphytic or lithophytic in growth and will use adventitous roots to climb on surrounding trees in order to seek more light and to support its weight; they can grow several metres in length. Under the right conditions S.grandiflorus will produce large sweet smelling flowers, which open at night.
Selenicereus meaning 'Moon Cereus', refers to the night bloom and the specific epiphet 'grandiflorus' comes from the Latin for 'large flowered'.
Pot: 14cm diameter.
Foliage: Approximately 30cm in length.
Secrets to success
Temperature: 24-28˚C. With cooler winter temperatures.
Light: Bright indirect light to shade with short periods of full sun.
Watering: The plant is quite resistant to drought but shouldn't dry out completely otherwise it will turn purplish brown and look unpleasant and should be permitted to dry out entirely between waterings. The adventitious roots seek out moisture in the air. Air humidity: Higher humidity is best.
Fertilising: Feed with a cactus fertiliser once a month during the growing season but this can lead to less flowers.
Potting mix: Use an airy mix containing orchid bark.
This plant is non-toxic but your pet or child may vomit if they ingest the plant.
