Orange flowers in blue planters = Happiness! No other color cheers or makes a garden glow more than orange. Waves of low, creeping red/orange lantana look fantastic in rock gardens. Masses of tall wispy orange coreopsis work with any backround. Easy to grow deep orange marigolds, esp tall varieties, planted by seed in large mounds are stunning show stoppers from a distance. I crowd them and they do wonderfully. Neighbors stop and ask, "What are those beautiful orange shrubs...?" Ha ha!
