Cornus foemina is a deciduous shrub producing a cluster of stems up to 8 metres tall[
]. Stems are around 10cm in diameter[
]. The plant does not have rhizomes[
The plant is harvested from the wild for local use as a medicine.
Southeastern N. Anerica - Illinois to New Jersey, south to Texas and Florida
Marshes, swamps, river and stream banks, pocosin margins, interdune swales, wet ditches; at elevations up to 1,500 metres[
Cornus foemina is not a very cold-hardy plant, tolerating temperatures down to around -8°c when dormant[
Succeeds in ful sun and also in partial shade[
]. Tolerant of many soil types, it requires a moist soil and will also succeed in wetter conditions[
]. Tolerant of poor soils[
The plant starts flowering when around 150cm tall[
The globose or oblate-ellipsoid fruit is pale blue, violet plumbeous, or blue violet in colour, often turning whitish blue to white; it is 5 - 6mm long and 6 - 10mm wide, the thin layer of flesh enclosing a single, large seed[
]. We have seen no reports saying that it is edible.
A decoction of the root or bark scrapings is used as a treatment for fevers, including malaria[
An infusion (part not specified) is used to treat lost voice[
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 warm stratification 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, 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[
Layering of new growth in early summer/July. Takes 9 months[
