Growth—

Cornus rugosa is a very cold-hardy tree, tolerating temperatures down to around -25°c when dormant. Succeeds in full sun or light shade[[1]. An easily grown plant, it succeeds in any soil of good or moderate fertility[2], ranging from acid to shallow chalk[3]. Grows well in heavy clay soils. Succeeds in poorly drained soils[3]. Plants commence flowering when about 100cm tall[4]. A very ornamental[2] and free-flowering plant[5]. 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[6, 7]. The seed must be separated from the fruit flesh since this contains germination inhibitors[6, 8]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[8]. Scarification may also help as may a period of warm stratification before the cold stratification[6, 8]. Germination, especially of stored seed, can be very slow, taking 18 months or more[8]. 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. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage[9]. Layering of new growth in early summer/July. Takes 9 months[9]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Cornus+rugosa>
