It has heart-shaped, dark green leaves
Kawakawa, or Macropiper excelsum, is a small tree or shrub native to New Zealand. It is also found on Lord Howe Island, Norfolk Island, and the Kermadec Islands. The name derives from the Māori language word 'kawa', meaning bitter, which refers to the taste of the leaves.
Kawakawa is renowned for its heart-shaped, dark green leaves, which are aromatic when crushed. The leaves are about 5-10 cm long by 6-12 cm wide, with prominent veining and a short drawn-out tip. They are opposite each other on the branch and are broadly rounded. The leaves are deep green in colour when growing in the forest, but may be yellowish-green in more open situations.
The heart-shaped leaves of the kawakawa plant are one of its most distinctive features. They are often covered with holes caused by the caterpillar of the kawakawa looper moth (Cleora scriptaria). Despite this, the leaves are still beautiful and aromatic. They have a fresh, herbal green note with an underlying spice finish similar to nutmeg. This is due to the presence of myristicin, one of the bioactive molecules also found in nutmeg.
The leaves of the kawakawa plant have a variety of uses. They can be crushed and smelt, with the aroma having a stimulating and rejuvenating effect. They can be brewed into a tea, which can be drunk to soothe the digestive system. The leaves can also be chewed to cure toothaches and treat bladder problems. Dried leaves can be burnt to create an insect repellent.
