Savannah White, also known as Pelargonium x hortorum, is an annual native to Southern Africa. Dummen developed this cultivar as a mid-season Geranium with superior heat tolerance among zonal varieties, good branching, and uniform flowering across the colors. This plant has an upright habit of 18-24" tall and wide, with semi-double white flowers from late spring to early fall. In addition to its long bloom season, this cultivar attracts hummingbirds, resists deer and rabbits, and flourishes in full sun or partial shade with moderate water. This Geranium is well-suited to patio containers and landscape borders. Create a striking color combination by pairing this color with Coral and Merlot Sizzle.

General Growing Tips For Your Rooted Cutting Liner
For best results with Savannah White, plant one rooted liner per 4-inch container, one or two per 6-inch container, two or three per 8-inch container, and three or four per 10-inch container. Use a well-drained soil with a pH of 6.0-6.4, EC of 2.0-2.5 (SME), temperatures of 65-75 daytime and 58-62 nighttime, and light feed (125-200 ppm N) at a 15-5-15 concentration. Keep soil moist, do not pinch, and spray Chlormequat for growth control if needed. Watch for thrips, aphids, fungus gnats, Xanthomonas, Rhizoctonia, and Botrytis.
White flowers bloom from late spring to early fall.
This plant doesn't require pinching.
Space containers for adequate airflow around the base of each plant and to allow sunlight to reach the soil level of each container. Don't allow foliage to touch.
Spray Chlormequat at 500-1,500 ppm as needed.
You may see aphids, whiteflies, thrips, spider mites, and fungus gnats.
Geraniums can be prone to a few diseases, including Xanthomonas, Rhizoctonia, Botrytis, and root rot.
Xanthomonas is a bacterial disease that causes leaf spots and death. It can lay dormant in plants and doesn't respond to bactericides. Prevent spread by removing infected plants, practicing good sanitation in your greenhouse, and watering at the base of each plant in the morning, allowing the soil to dry between waterings.
Rhizoctonia is a fungal infection that thrives in warm, moist soil, causing stems, roots, and leaves to rot. The most important preventative measure against this disease is to practice good sanitation with your planting media. Rhizoctonia will respond to fungicides.
Prevent Botrytis and root rot by watering at the base of each plant, allowing the soil to dry slightly between waterings, growing plants in full sun, and providing excellent airflow in your greenhouse. We recommend using horizontal airflow fans.
Planting Savannah White Liners
We recommend planting one rooted liner per 4-inch container, one or two per 6-inch container, two or three per 8-inch container, and three or four per 10-inch container. Use a well-drained soil and completely bury the ellepot centered or evenly spaced in the container. Six-inch containers finish in 6-10 weeks and 8-inch containers finish in 6-11 weeks.
Rooted Cuttings Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
