Pelargonium ‘Savannah® Oh So Orange’ Brightens Borders with Fiery Flair
Pelargonium ‘Savannah® Oh So Orange’, commonly known as Savannah Oh So Orange Geranium, is a dazzling choice for gardeners seeking bold, cheerful color from spring through fall. This cultivar belongs to the Geraniaceae family and is part of the well-regarded Savannah® Series, bred by Dümmen Orange. With its semi-double vivid orange blooms and exceptional resilience, this zonal geranium adds nonstop visual excitement to beds, containers, and hanging baskets.
Ornamental Appeal of Pelargonium ‘Savannah® Oh So Orange’
The standout feature of Pelargonium ‘Savannah® Oh So Orange’ is its vibrant orange blossoms. These lightly-scented, semi-double flowers appear in rounded clusters atop upright stems. They create a striking contrast with the dark green, tomentose, palmate leaves, which often show distinctive brown zones. Flowering begins in late spring and continues unabated into early autumn with proper care.
Rising to a mature height of 30–45 cm (12–18 inches) and spreading about 30–50 cm (12–20 inches), the plant maintains a compact, upright habit. This makes it a stellar “thriller” for container arrangements or a vibrant focal point in garden beds. Each stem can carry multiple blooms, contributing to a profuse and extended flowering display.
How to Grow Pelargonium ‘Savannah® Oh So Orange’
Light
To perform its best, Pelargonium ‘Savannah® Oh So Orange’ requires full sun to partial shade. Ideally, it should receive 6–8 hours of direct sunlight per day. In extremely hot regions, a bit of afternoon shade helps prevent leaf scorch and encourages lush growth.
Soil
This geranium thrives in well-drained soils with a pH between 6.0 and 7.0. While it isn’t fussy about soil type, incorporating organic matter like compost or perlite improves drainage and supports healthy root development.
Watering
Water consistently, allowing the top layer of soil or potting mix to dry slightly between waterings. Avoid waterlogging the soil, as standing moisture can lead to root rot, especially in containers. During establishment and hot periods, regular watering is essential, but once mature, the plant becomes moderately drought-tolerant.
Fertilizing
For sustained blooming, feed every 2–4 weeks during the growing season with a balanced liquid fertilizer. Container-grown plants may need more frequent feeding to support constant growth and flowering.
Pruning and Maintenance
Deadhead spent flowers regularly to prolong bloom cycles. In late autumn, once flowering slows, prune the plant back by one-third to one-half to encourage dense, bushy growth the following spring. Regular tidying also helps maintain a clean, vigorous appearance.
Propagation of Savannah® Oh So Orange
This cultivar can be propagated from cuttings. Take healthy, non-flowering stems and root them in moist, sterile potting mix under bright, indirect light. However, as a patented or trademarked variety, propagation may be restricted for commercial purposes, so always check legal permissions if producing for sale.
Pests and Diseases
Pelargonium ‘Savannah® Oh So Orange’ is relatively pest-resistant but may occasionally attract whiteflies, aphids, or spider mites. Regular inspections and good air circulation help prevent infestations. Fungal issues such as botrytis or root rot can occur if overwatered or if air circulation is poor—especially in dense plantings or humid environments.
Landscape and Container Use
This cultivar offers exceptional versatility in the garden:
- Mass Plantings: Use it en masse to create blazing seasonal borders.
- Edging and Borders: Its tidy growth habit makes it ideal for lining paths or flower beds.
- Containers and Baskets: A showstopper in patio pots or hanging baskets, where its upright growth and bright blooms add visual impact.
- Urban Gardens: Tolerates urban pollution well, making it suitable for city balconies and rooftops.
When used in the “thriller-spiller-filler” formula for containers, place Savannah® Oh So Orange at the center (the “thriller”), pairing it with cascading and mounding plants for a layered look.
Environmental Tolerances
One of the strongest selling points of this cultivar is its heat tolerance. It holds up well through hot summers without fading or wilting—ideal for USDA Hardiness Zones 10 and warmer when grown as a perennial, though it is generally treated as an annual in colder zones. Once established, it is moderately drought-tolerant and deer-resistant, making it low-maintenance for busy or novice gardeners.
