Orchid blooms typically last between 6 to 12 weeks, depending on the species and care conditions. For example, Phalaenopsis orchids, one of the most common types, usually keep their flowers for about 2 to 3 months, though with excellent care some can bloom for even longer, up to 6 to 10 months in rare cases

. Key points about orchid blooming duration and care:

• Most orchids bloom for about 6 to 10 weeks on average, with some lasting up to 12 weeks

• With optimal light, humidity, watering, and fertilization, blooms can be prolonged. Proper care can sometimes extend blooming to several months

• After blooming, orchids enter a resting phase before they rebloom, which can take 8 to 12 months, though some orchids may rebloom sooner or multiple times a year

• Orchids can live and bloom for many years (15-20 years or more) if cared for properly, producing flowers twice a year or more

In summary, orchid flowers generally last from 6 weeks to 3 months, but with good care, some species like Phalaenopsis can maintain blooms for much longer periods, even up to 10 months or more. After flowering, orchids rest before reblooming, often annually.
