Family: Cornaceae
What it is like
Cornus walteri is a deciduous Tree growing to 10 m (32ft 10in). See above for USDA hardiness. It is hardy to UK zone 6. It is in flower from May to June, and the seeds ripen from August to October. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Height (m): 10

How it is grown
An easily grown plant, it succeeds in any soil of good or moderate fertility, ranging from acid to shallow chalk. Grows well in heavy clay soils. Succeeds in full sun or light shade. Plants in this genus are notably resistant to honey fungus. This species is closely related to C. wilsoniana.
Propagating it: Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed. The seed must be separated from the fruit flesh since this contains germination inhibitors. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year. Scarification may also help as may a period of about 3 days warm stratification at 15°c before the cold stratification. Germination, especially of stored seed, can be very slow, taking 18 months or more. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage. Layering of new growth in June/July. Takes 9 months.
