Cotoneaster horizontalis is a short shrub with a spreading habit. It is cultivated for its flat, symmetrical sprays of glossy green, deciduous leaves, and masses of bright red berries (pomes) in autumn, persisting into winter. The flowers appear in summer, and can range from pink to white. It is commonly grown as a Bonsai, and also in parks and gardens in temperate regions as hedging or groundcover. This plant has gained the Royal Horticultural Society's Award of Garden Merit!

These plants are sometimes used for bonsai, though they can be grown as a regular full-sized tree. If growing as a Bonsai, we are offering our Bonsai growing instruction booklet as an option with your seeds. It contains full-colour images and detailed information about germinating, growing, pruning and potting your new bonsai! It is the same booklet that is offered in our bonsai kit.

Hardiness zones: 5-7

Location: Sun or part sun

Seeds: These seeds are shipped as dried berries. The entire berry can be planted.

Berries/seeds per pack: 10

Note: These seeds and plants can be harmful if eaten. Ingestion can cause illness such as vomiting or diarrhea.

Germination: Pour boiling water over the berries/seeds and let stand in water for 24 hours. Plant 2-3 seeds in each pot, just under the surface of a seed-start mix. Water, and cold stratify for 90 days (a refrigerator works well). If you are starting your seeds during the cool weather, the pots can be placed in a cold garage. Once the cold period is completed, place the pots in a warm, sunny spot. You should see the first sign of germination within the next few days or weeks, depending on the variety. Generally a 10-60 day range is normal for the first signs of growth. When the seedlings are about 5cm (2") tall, remove any additional plants and leave only the strongest seedling in each pot. The removed seedlings can be planted in a garden or elsewhere if desired.
