Orange is an evergreen citrus tree known for its fruit, ornamental foliage and fragrant flowers. They should be planted in the warmest part of the garden protected from frost and wind. Often planted close to the house near windows (for fragrance,flowers and foliage) or on a sunny wall, it is important that they are watered regularly/consistently. Plant in full sun situation, well-drained, organically enriched, slightly acidic soils, they should be mulched to protect the surface feeding root-systems. Handweeding a small circle around the base will insure grass growth does not effect the root systems if planted into a lawn area. Citrus also does very well planted in free-draining containers and pots.
