Growth—

Cornus kousa chinensis is a very cold-hardy tree, tolerating temperatures down to around -25°c when dormant[1]. An easily grown plant, it succeeds in any soil of good or moderate fertility[2], ranging from acid to shallow chalk[3]. Does not like chalky soils according to other reports[1, 4]. Grows well in heavy clay soils. Prefers a rich well-drained loamy soil and a position that is at least partially sunny[5]. A very ornamental plant[2]. A number of named forms have been developed for their ornamental value[6]. Plants are slow-growing when young, they speed up somewhat after a few years but then soon slow down again[7]. This sub-species of Cornus kousa grows more freely, flowering and fruiting better in areas with cooler summers, though it barely differs in appearance from the species[5]. Plants usually start flowering when around 200cm tall[8]. Plants in this genus are notably resistant to honey fungus[3].

Propagation

Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[9, 10]. The seed must be separated from the fruit flesh since this contains germination inhibitors[9, 11]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[11]. Scarification may also help as may a period of warm stratification before the cold stratification[9, 11]. Germination, especially of stored seed, can be very slow, taking 18 months or more[11]. 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, mid summer in a frame[4]. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage[12]. Layering of new growth in early summer/July. Takes 9 months[12].
