Took two years (including two winters) to flower. It should have vernalized without issue the first winter, but there was not a single flower after the first year. In year two, it flowered very well and were attractive. However, due to the unpredictability as to whether it will flower in one year or two (which it's not worth the wait), it is better to use a cultivar we feel more comfortable with and is more reliable.

Recommendation: Do not use again, use another cultivar.
