Answer:
In answer to your question about growing Winterberry, Ilex vertillata, you can use the berries from current plants. If the berries are still firm enough, put them in a plastic bag and let them ferment. When soft enough (might take a week) to squish, separate the clean seed. Place the seeds in a pot. Winterberry is pretty tolerant of soils but it does grow in acidic soils in nature. Sprinkle sand (builders sand is best) over the top to cover. Place the pot(s) outside, it will need about 6 weeks of cold temperatures, out of direct sun, so it doesn’t dry out. This a very slow-growing shrub, and it may take until the following Spring before a new shoot appears.
