Jasmine growth rates vary depending on the species and growing conditions, but generally, jasmine plants grow moderately to fast.

• Star Jasmine (Trachelospermum jasminoides) grows about 30 to 90 centimeters (approximately 1 to 3 feet) per year. With good care-adequate watering, fertilizing, and maintenance-it can reach up to 6 meters (about 20 feet) in length if grown as a vine or creeper

• Common Jasmine (Jasminum officinale) grows moderately fast, typically about 12 to 24 inches (1 to 2 feet) per year, reaching 10 to 15 feet at maturity when supported as a vine or pruned as a shrub

• Jasminum polyanthum is a fast grower, potentially reaching 3 feet per year and maturing within 1 to 2 years, while other jasmine species like Jasminum sambac grow more moderately, taking 2 to 3 years to mature

• Climbing jasmine varieties can grow 1 to 2 feet per year and may take 3 to 5 years to reach full size, sometimes growing up to 20 feet tall under optimal conditions

• Dwarf jasmine (Jasminum parkeri) grows more slowly, typically reaching 1 to 3 feet over 2 to 3 years, depending on sunlight, soil quality, and watering

In summary, jasmine plants generally grow between 1 to 3 feet per year under good conditions, with some species and vines capable of faster growth up to 6 feet annually. Full maturity is usually reached within 1 to 5 years depending on the variety and care
