Clove (Floris caryophylli) The clove tree is a species of plant in the myrtle family (Myrtaceae). The cloves are the strongly fragrant and burning hot tasting dried flower buds of the plant species originally native to the Spice Islands. The clove tree grows as an evergreen tree and can reach a height of over 10 metres. The clove is a traditional incense in Asia as an additive to incense sticks. The smoke drives away evil spirits as well as insects and creates a spiritual atmosphere. Clove is also sexually stimulating and is said to attract wealth.
