Answer: Different clematis varieties bloom at different times, and the pruning schedule can also influence the bloom time each year. In general, clematis is slow to establish and may take several years to really bloom the way we hope for. There is an old saying that clematis sleeps the first year, creeps the second, and leaps in the third. There is also a fragrant, fall blooming white flowered clematis, so perhaps this is the one you have. The typical dark purple-flowered Jackman clematis is one of the most vigorous varieties--this is one of the reasons for its popularity.
