Allow them to grow for 1 or 2 years before planting them in a permanent position. Growth in the first year is usually between 10 and 50cm depending on the time of germination and cultural techniques and developing seedlings are usually trouble free. Keep the seedlings well watered and weed free. Fresh seedlings can keep germinating for several years after the original sowing date.ĭo not expose newly sown seeds to high temperatures (above 25 Celsius). Ungerminated seeds can have the whole warm and cold process repeated again to enable more seeds to germinate. It has also been found that fluctuating pretreatment temperatures can give the best germination results and I have myself had excellent results by keeping the mixed seeds in a cold shed through the winter for the cold stage of their pretreatment and allowing the temperature to fluctuate naturally. For larger quantities it is easiest to sow the seeds in a well prepared seedbed outdoors once the warm and cold pre-treatments have finished and wait for the seedlings to appear. Small quantities can be sown in pots or seed trays filled with a good quality compost and cover them with a thin layer of compost no more than 1 cm deep. When the period of pre-treatment has finished the seed should be ready to be planted. When the dormancy has been broken it is quite possible for the seeds to germinate in the bag at these temperatures, if they do, just remove them from the bag and carefully plant them up. During this time make sure that the pretreatment medium does not dry out at any stage or it will be ineffective!įollowing this the seeds require a cold period to break the final part of the dormancy, this is easily achieved by placing the bag in the fridge at (4 Celsius or 39F) for at least 12 weeks (possibly up to 29 weeks). The leaves are bright yellow in early to mid-spring when they emerge gradually turning a bright, light green in summer. The seeds first require a period of warm pretreatment and need to be kept in temperatures of 20 Celsius (68F) for a period of around 12 weeks. Cornus mas 'Aurea' Cornelian Cherry Plant Type: DECIDUOUS SHRUBS Cornus mas 'Aurea' - This is the golden foliage form of Cornelian Cherry. Then write the date on the bag so that you know when the pretreatment was started. Place the seed mixture into a clear plastic bag (freezer bags, especially zip-lock bags are very useful for this -provided a little gap is left in the seal for air exchange) If it is not a zip-lock type bag it needs to be loosely tied. Mix the seeds into the substrate, making sure that their is enough volume of material to keep the seeds separated. The chosen substrate needs to be moist (but not wet), if you can squeeze water out of it with your hand it is too wet and your seeds may drown and die. Is deer tolerant.Seeds of the Cornelian Cherry have a deep dormancy within them, this requires a degree of patience to overcome and it is usually quite easy to get high levels of germination if the correct procedures are followed.įirst prepare a free draining substrate into which the seeds are to be mixed, this can be a 50/50 mixture of compost and sharp sand, or perlite, vermiculite. Use as a border, hedge or screen or as a specimen. Will grow in many soil types including damp clay, medium moisture to well-drained soil. Is tolerant of a wide range of pH from 5.0 to 8.0. This deciduous shrub or multi-trunked small tree has a mature height of 15 to 25 feet tall and 15- to 20-foot wide. native to central and southern Europe and parts of western Asia hardy to zone 4 Habit and Form. Berries also attract birds and other wildlife. Cornus mas Cornelian Cherry Dogwood Cornaceae. Can make a sauce similar to cranberry sauce when berries are pitted and boiled, and then ground with sugar and orange peel. Berries have an acidic tart flavor, best described as a mixture of cranberry and sour cherry. Eaten fresh or dried, need to be fully ripe to lose their tartness. This is one of the earliest shrubs to bloom, with berries which resemblance coffee berries that can be used for preserves, jams, sauces and juice that are used for syrup, drinks, and to make alcoholic beverages. Yellow flowers bloom in late winter / early spring before leaves develop and an appearance similar to forsythia, but earlier.
