Citrus trees grown as ornamental container plants may take up to five years to produce fruit. Container-grown ornamental orange trees are usually the dwarf varieties which grow to a height of 4 to 10 feet. Limited root space has the effect of stunting tree growth even if it is a standard variety. Citrus trees are damaged at frost temperature but can be grown in wintertime indoors.
