My black pine has a flower cluster on one of the branch tips, does this mean I will see pine cones sometime this year? What must happen for it to produce seeds? thanks
Usually the clusters are the pollen cones which will disperse pollen and then dry up and fall off. If there is a seed cone it will look very different, on JBP they are blue-ish when they first come out and they stick up above the candle. They take two years to mature I believe and seeds are normally only viable when the tree is growing vigorously (but it's possible they could be viable otherwise.) I've left a seed cone on for a year before but took it off after that when I realized it was another year to mature.
My JWP has purple pollen clusters every year, it's never produced cones. Is it true that pines are either male or female (I think the term is 'monoecious')? If so, you may have a male tree.
Pines are male and female (Dioecious)
