This crop is suitable for growing in containers, garden plots, raised beds, and greenhouses.

Vigorous, stress-tolerant plants branch well without pinching and hold color through summer heat.
Growing Silver Shield Plectranthus in the Flower Garden
For best results, start pelleted seed indoors 6 to 8 weeks before transplanting. Surface-sow the pellets and gently press them into the media without covering them, then keep them evenly moist and warm for germination. Harden off seedlings and transplant after the last frost.
Space plants 24 to 32 inches apart in full sun to partial shade. Silver Shield prefers even moisture while establishing, then tolerates short dry periods. It is grown mainly for foliage, so pinch is not required - simply harvest or lightly trim tips to shape plants in containers.
Harvesting of Silver Shield Plectranthus
Harvest foliage stems any time once plants are established. Cut above a leaf node to encourage branching, and use fresh stems for mixed planters, bouquets, or seasonal arrangements.
About Silver Shield Plectranthus Garden Seeds
Silver Shield is a seed-grown plectranthus selected for strong branching, stress tolerance, and bold silver leaves. Plants form a mounded, upright accent that pairs well with bright flowers and darker foliage for high-contrast displays.
Use it as a centerpiece in patio pots, as a massed bedding plant, or as a foliage accent in cutting gardens where the soft silver texture elevates arrangements.
Tips From Our Gardeners
To keep foliage clean and silver, avoid overhead watering and let the soil surface dry slightly between waterings. A little morning sun with afternoon shade is a great balance in hot summer climates.
