Aloe vera plants are usually between 12 and 24 inches tall (30 to 60 cm). They form a beautiful rosette of long, fleshy leaves that can spread out to about 1-2 feet (30-60 cm) wide, so you'll have plenty of room to grow and enjoy them! In the right conditions, some varieties can even grow up to 3 feet (90 cm) tall — isn't that amazing?
