Christmas cacti are tropical plants native to Brazil that can live for 20-30 years, or even up to 100, and are non-toxic to pets. Unlike traditional desert cacti, they are epiphytes, meaning they grow on trees in the rainforest and need high humidity and indirect light, as well as cool temperatures to bloom. While they have “cactus” in their name, their care requirements are more like a succulent, with overwatering being a common cause of death.
Unique characteristics
Pet-friendly: Unlike poinsettias, Christmas cacti are not toxic to cats and dogs.
Tropical origin: They are not desert plants but are epiphytic succulents from the tropical rainforests of Brazil.
Long lifespan: They can live for a very long time, with some specimens living 20 to 30 years or even longer, sometimes being passed down through generations.
Care and blooming
Cooler temperatures: Despite their name, they thrive in cooler temperatures and need a period of cool, dark conditions to encourage blooming.
Light for blooms: They need light to bloom, but dislike direct sunlight, which can cause their stems to turn reddish.
Darkness for dormancy: They require a period of darkness for 12-14 hours a day for about 6-8 weeks to trigger flowering.
Watering: Overwatering is a common mistake; they prefer their soil to dry out slightly between waterings, but enjoy being misted to stay humid.
