COLEUS Rainbow Mixture Annual-One Season Plant - Height 12 to 18 inches Colorful foliage makes this an outstanding house or garden plant. A wide range of different colors on heart shaped leaves make brilliant splashes in beds, borders and containers. Easy to grow. Use partial shade or a mostly shady spot. Special Directions For Short Season Climates SOWING: Start seeds indoors in late winter through early spring. Sow in trays or flats, firm seed into soil with the back of hand. Do not cover seed with soil as it needs light to germinate. THINNING AND TRANSPLANTING: Thin or transplant seedlings to 2 inches apart when 1 inch tall or pot individually. SPACING: Leave 10 to 12 inches between plants outdoors. GERMINATION: 10 to 12 days at 70 degrees. Keep soil moderately moist during germination. Ed's Special Advice Prefers rich, moist well-drained soil. Plants can be moved in the fall for use indoors as winter houseplants. Pinch center stem when plants are 4 to 6 inches tall for bushier growth. Pick off flower heads as they form. Leaf color is best when planted in a semi-shady spot.
