Like all holly, the Grace Hybrid American Holly requires a male pollinator plant for the female plant flowers to develop into berries. One male plant can produce enough pollen to service many female plants. Remember that the male plants have no fruit, so all energy will go to growth instead of fruit development. this is why the male plants grow faster and less compact. In formal setting, where a matching pair of holly are needed, both plants should be same sex so they will continue to grow at at similar rate. We recommend that the male be within 200 yards of the female for adequate pollination.
