Several distinct varieties of passion fruit with clearly differing exterior appearances exist.<ref name="morton" /> The bright yellow ''flavicarpa'' variety, also known as yellow or golden passion fruit, can grow up to the size of a [[grapefruit]], has a smooth, glossy, light, and airy rind, and has been used as a [[rootstock]] for purple passion fruit in Australia.<ref name="morton" /> The dark purple ''edulis'' variety is smaller than a [[lemon]], though it is less acidic than yellow passion fruit, and has a richer aroma and flavour.
