Blue Star Juniper (Juniperus squamata 'Blue Star') is a dwarf, evergreen shrub that is commonly used as a landscaping plant. It is known for its striking blue-gray foliage and compact, spherical growth habit.

When it comes to pollination, Blue Star Juniper is a dioecious plant, which means that there are separate male and female plants. The male plants produce pollen, which is carried by the wind to the female plants, where fertilization takes place. Therefore, it is important to have both male and female plants in close proximity for successful pollination and fruit production.

It is also worth noting that Blue Star Juniper is not typically grown for its fruit (juniper berries), but for its ornamental value. The berries are small and round, and are typically blue or black in color.
