English ivy is a hardy, evergreen vine or groundcover. As a vine, it attaches itself by aerial rootlets to masonry walls and other surfaces such as tree trunks.
European in origin, it has glossy, dark green leaves with a prominently lobed, maple-like shape. As plants grow aerially, they develop bushier, more mature growth and develop sharper, triangular leaves with no lobes. There are hundreds of cultivars are available, most with beautifully variegated leaves of various shapes, colors and sizes.
English ivy is dioecious, meaning that single plants produce either male or female flowers. Mature plants put forth inconspicuous pale yellow-green blooms in summer and female plants produce black, berry-like fruits late in the season. These fruits are eaten and spread by birds.
Vigorous and easy to grow, English ivy can tolerate full sun to shade, though partial shade is recommended in hot climates, and prefers fertile soil with good drainage. This often aggressive vine may become invasive. It can be particularly detrimental to trees and can cause premature decline or death if allowed to grow up and overtake them.
English ivy is grown primarily for its lush foliage, which forms a cool, green cover on walls or ground. It looks great in containers and hanging baskets or can be sheared and trained as topiary. (info source: Learn2Grow.com)

|1. Soak seeds for 24 hours in a warm water
2. Stratify for 1 month in dampened peat or sand, in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium.
3. After the seeds are stratified, plant them a 3-5 mm deep in a container filled with a moist, well-drained germination medium. Tamp the soil. Cover with glass or plastic and keep the container moist, but not soggy. Seeds should germinate at room temperature. As soon as the seeds germinate, place them under bright lights or move them to a greenhouse or cold frame.
Another method is to plant seeds outdoors in well prepared beds in October or before the winter. If it does not rain, then water the seedbeds before the ground freezes. The seeds will naturally receive cold treatment during the winter. The seeds should start to germinate when the seedbed warms up in the spring.
When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter. Plant out in late spring.
