Hyacinths typically bloom once per year in early to mid-spring, with their flowering period lasting about two to four weeks depending on conditions. Individual flowers on the stalk last around five to seven days, but the overall bloom on a plant can extend up to about three to four weeks

. After blooming, the flower stalk should be cut back while allowing the leaves to remain until they yellow and die back naturally. This process helps the bulb store energy for the next season's bloom. With proper care, hyacinths are perennial and can bloom for several years, often around 3 to 5 years, although bloom quality may decline over time, especially in hybrid varieties

. In summary:

• Bloom time: early to mid-spring
• Duration of bloom: about 2 to 4 weeks total per season
• Individual flowers last about 5 to 7 days
• Perennial bulbs that can bloom for multiple years with proper care

This makes hyacinths a relatively long-lasting spring bulb bloom compared to many others, providing vibrant color and fragrance for several weeks each year
