Pollination Information for Dwarf Japanese Cedar (Cryptomeria japonica 'Globosa Nana')

Dwarf Japanese Cedar (Cryptomeria japonica 'Globosa Nana') is a coniferous evergreen shrub that belongs to the family Cupressaceae. It is a popular ornamental plant in gardens and landscapes due to its beautiful foliage and compact growth habit.

Pollination

Dwarf Japanese Cedar (Cryptomeria japonica 'Globosa Nana') is a monoecious plant, which means that it has separate male and female cones on the same plant. The male cones produce pollen, while the female cones produce seeds.

Pollination occurs mainly through wind, as the pollen from the male cones is carried by the wind to the female cones. However, pollination can also occur through cross-pollination by insects such as bees and butterflies.

Fertilization

After pollination, the pollen grains from the male cones will land on the female cones, where they will fertilize the ovules. The fertilized ovules will then develop into seeds.

Seed Dispersal

Once the seeds are mature, the cones will open up to release the seeds. The seeds are dispersed by wind or animals.

Cross-Pollination

Cross-pollination can occur between different cultivars of Cryptomeria japonica, but it is unlikely to occur between different species of the same family. Therefore, it is important to ensure that neighboring plants are of the same cultivar to maintain the desired characteristics.
