Organic growing matter such as compost or sphagnum moss
Lantana, also called White Sage, is a tropical woody shrub that produces small clusters of tiny, colorful flowers in shades of pink, yellow, red, orange, purple and white. This perennial is evergreen in zones 9 and warmer but gardeners in cool climates can enjoy lantana shrubs as an annual or grow them in containers to be brought indoors during the winter. Lantana is a versatile and tolerant plant, perfect for growing as borders, ground cover, hanging baskets and containers and able to withstand drought, salty climates and poor soils. Though lantana's scent is not particularly appealing to humans, the fragrance, along with the plant's berries and flowers, attracts butterflies, bees and hummingbirds. Sow lantana seeds in an area where you can enjoy watching these creatures fly to and from your plant.

Choose a partially-protected planting site with full sun such as the side of a house or fence for outdoor growing; indoor gardeners should choose a window with plenty of bright sunlight.
Wait until lantana seeds turn a purplish-black color before sowing; green seeds are not yet ready to be planted.
Soak lantana seeds in warm water for 24 hours before planting them.
Prepare the planting soil: lantana thrives in well-drained, peaty soil so add plenty of organic matter such as compost or sphagnum moss.
Sow seeds in the soil at a depth of 1/8-inch.
Water thoroughly after planting, and maintain average to slightly dry soil thereafter.
Expect seeds to germinate in about eight weeks.
Lantana plants are hardy only in USDA zones 9 to 11 so gardeners in cooler climates can sow seeds in containers to protect them during the winter months or prepare to replant lantana every year if grown outdoors. Deadhead wilted flowers to encourage more blooms. A lantana plant that displays yellow leaves with brown edges is probably receiving too much water.
Lantana seeds and plants are poisonous so keep seeds safely out of the reach of children and pets and monitor their activity near established plants.
