The peel is thin, smooth and greenish yellow when ripe. The flesh is also greenish-yellow and full of highly poly embryonic seeds (two or more plants from one seed). The interior is divided by 10 to 12 segments, quite juicy and has a higher acidity than Persian limes. Key limes have a very distinctive aroma which makes them valuable for culinary use. They make a good house plant.1

This variety typically produces fruit in the following colours:   Forest green (web) and   Apple green. The leaves of this particular variety normally show as   Sap green colour. It is a flowering edible fruit that typically grows as an evergreen, which is defined as a plant that retains leaves throughout the year. Key lime is known for its tree habit and growing to a height of approximately 2.50 metres (8.12 feet).
