Shenandoah Coleus
Plectranthus scutellarioides 'Shenandoah'
flowerShenandoah is a striking foliage coleus variety prized for its dramatic deep burgundy and wine-red leaves with contrasting chartreuse-yellow center veining and margins. This tender perennial is grown as an annual in most climates and is valued primarily for its ornamental foliage rather than flowers. It thrives in containers and garden beds, adding bold color contrast to shade and partial-shade plantings.

Seedling
2-3 weeksSmall leaves emerge with basic coloring; plant is compact and delicate
Keep soil warm (70-75°F) and consistently moist. Provide bright indirect light. Begin fertilizing lightly at 2-3 weeks.
Vegetative Growth
3-5 weeksPlant develops multiple stems and fuller foliage; characteristic burgundy-wine coloring with yellow veining becomes apparent
Pinch out growing tips to encourage bushiness and branching. Apply balanced, diluted fertilizer every 1-2 weeks. Maintain consistent moisture.
Mature Foliage
4-8 weeksPlant reaches full ornamental size with dense, vibrant purple-red leaves and prominent yellow-green veining throughout
Continue pinching stems as needed to maintain compact shape. Fertilize every 2 weeks with a balanced formula. Watch for spider mites and mealybugs in dry conditions.
Flowering (Optional)
6+ weeksSmall purple-lavender flower spikes emerge at stem tips; foliage remains the main ornamental feature
Pinch off flower buds if you want to maximize foliage production and energy. Allow flowering if you prefer a more natural appearance.
Decline/Frost Sensitivity
Variable with seasonPlant slows growth as temperatures drop below 50°F; leaves may pale or drop; plant dies with frost exposure
In zones 3-9, bring container plants indoors before first frost (typically October). Keep as houseplant or take cuttings to propagate for next season.

Common Pests
-
Increase humidity, mist foliage, spray with neem oil or insecticidal soap every 3-4 days until controlled. Remove heavily infested leaves.
-
Spray with insecticidal soap or neem oil; isolate plant to prevent spread. Dab clusters with rubbing alcohol on cotton swab.

Uses
Ornamental container and landscape display
CraftShenandoah coleus is exceptional for creating dramatic focal points in shade gardens, container arrangements, and mixed planters. Its burgundy-wine foliage with yellow veining provides striking color contrast against other plants and hardscape. [source]
Indoor houseplant and winter propagation
HouseholdIn colder zones, Shenandoah thrives as a winter houseplant on bright windowsills or under grow lights. Cuttings root easily in water or soil, making it simple to maintain or propagate year-round indoors. [source]
Pollinator support
WildlifeWhile grown primarily for foliage, Shenandoah's delicate purple flower spikes attract bees and other beneficial insects when allowed to bloom, supporting pollinator populations in gardens. [source]
Edible foliage (some coleus varieties)
CulinaryWhile ornamental coleus varieties like Shenandoah are technically safe to consume in small amounts, they are not primarily grown for eating. Some specialty coleus cultivars are bred specifically for culinary use with different flavor profiles. [source]
Harvest Tips
Shenandoah is harvested for foliage display rather than food or seeds. Pinch stems regularly from 4-6 weeks onward to encourage bushier growth and maintain ornamental shape. Cut stems 1/4 inch above a leaf node. Foliage is prime for display from midsummer through early fall (zones 3-9) or year-round in warm climates. In zones 3-9, take 4-6 inch cuttings in late summer to propagate indoors for winter houseplant care or next season's garden.
Fun Facts
- 🌱 Shenandoah coleus cuttings root so readily in water that they can be propagated year-round indoors, making them one of the easiest plants to share with friends and family.
- 🌱 The vibrant purple-red coloring in Shenandoah leaves is produced by anthocyanin pigments, the same compounds that make blueberries blue and red apples red—providing natural UV protection for the plant.
- 🌱 Coleus is native to Southeast Asia and has been cultivated in Indonesia for thousands of years, where it was traditionally used in medicine and as a culinary herb before becoming a globally beloved ornamental foliage plant.
