Native To Australia
Thryptomene Calycina , commonly known as Heath Myrtle or Grampians Thryptomene, is a beautiful evergreen shrub. A member of the Myrtle family, common relatives include the bottlebrush plant, myrtle and eucalyptus. The name comes from the Greek word Thryptomene, meaning “made small” (alluding to its small size) and Calycina which refers to the showy calyx of it inflorescence. Native to Australia, Heath Myrtle grows wild on the rocky mountainsides of southwest Victoria (particularly in the Grampian region) where it has been listed as a rare or threatened species.
The Thryptomene Calycina plant, classed as a dicotyledon, is a bushy shrub growing 5-8 ft. tall, with small aromatic, lance shaped leaves that are not parallel veined. The plant stems reach 24-36” in length and have a reddish tint in the summer. Although the shrub appears healthy and attractive in all seasons, the show stopper of this species is its beautiful flowers. Available in white, pink or white and pink, with yellow centers, they form spectacular calyx shaped blooms in autumn through spring. In good seasons, the blooms are so numerous that they cover the entire branch of the flower, blanketing the area in white (or pink). They also have an appealing scent.
Growing Recommendations - Thryptomene Calycina
Heath Myrtle makes an ideal shrub border, requiring light sandy loam to clay loam soil (free from lime), a ph level of 5-7, normal water levels and full sun. It is not overly susceptible to pests or diseases. It is best to keep the shrubs rounded and bushy to protect the stems from winds and snow. Young plants are obtained from cuttings and may be purchased at nurseries. Thryptomene Calycina also makes a great choice for cut flowers since its vase life is up to several weeks. Extend the vase life by changing the water every 3 days, adding a florist’s fertilizer if available.
