Cornus racemosa, commonly called gray dogwood, is a deciduous shrub which is native to Missouri and typically occurs in moist or rocky ground along streams, ponds, wet meadows, glade and prairie margins, thickets and rocky bluffs. It grows 10-15' tall and features white flowers borne in terminal racemes (hence the species name of racemosa) in late spring and grayish-green, elliptic to lance-shaped leaves (2-4" long). Foliage turns an interesting (but not always showy) dusky purplish red in fall. Terminal stems holding the flowers are distinctively red and provide interesting contrast to the clusters of small white berries which form after the flowers have dropped. Red stem color is more easily seen after the fruits are gone, and red color often persists into early winter.
Excellent when planted in groups and left alone to spread in naturalized areas or native plant gardens. Also effective in shrub borders, along streams or ponds or near buildings or when planted as a screen. Can be particularly useful because of its ability to grow in poor soils.

| Germination | 1. Soak the seeds in warm water for 24 hours. 2. Fill a nursery flat or other germination container, to within 10 mm of the rim, with a sterile germinating mix. Moisten the mix thoroughly. 3. Sow the seeds ~2 mm deep in the mix. Moisten the seeds and place the flat in a cold frame or in the refrigerator at +2-+4C (35-39F) for 60 days. Keep the seeds moist during this period. 4. Remove the flat from the refrigerator and place it in an area with indirect sunlight and where the temperature remains between +15-+20C (60-68 F). 5. Keep in good ventilated room or place. Good air circulation is required. 5. Spray the seeds periodically with room-temperature water from a misting bottle to ensure they remain moist. Seeds typically germinate within 20 days to three months. |
