Light Exposure:

full sun or partial shade.

Soil type:

medium-textured soil tending towards compact. Fears water stagnation. It tolerates calcareous soils poorly.

Soil acidity:

pH 6,0 – 7,5. It has little tolerance for soils with a highly basic pH, which are often responsible for leaf chlorosis.

Italian climatic area:

Naturalized in most Italian regions, including islands. In marine locations in central Italy, in  Southern Italy, in  Sardinia, in  Sicily  and in  Liguria.

Irrigate medium-abundantly in spring-summer if it doesn’t rain for a long time; scarce in winter.

Propagation:

Pittosporum reproduces by seed and semi-woody cuttings.

Pruning:

after flowering and you will have to proceed to reduce the foliage by about a third, eliminating the terminal part of the foliage

Diseases:

It is naturally resistant to parasitic attacks. Attacks by  cochineal insects and in particular by cotonous scale insects can be very serious if action is not taken promptly.

However, it tolerates calcareous soils with a highly basic pH, which are often responsible for leaf chlorosis

PARTICULARITY

The name Pittosporum derives from the Greek pitta = “pitch” and sporos = “seed”; it therefore means “resinous seeds”, to allude to the fact that the seeds of this genus are covered in a sticky substance similar to resin. The specific name tobira is the transcription of the Japanese term tobira, abbreviation of the expression tobira no ki, which means “door tree”, as it was customary to attach twigs of this plant to the door jambs, as an  apotropaic talisman.

Annotations

They are plants much visited by  bees  for their  nectar  and, if present in sufficient quantity, can produce excellent  honey.

Resistance to salt and urban pollution.

Two interesting varieties are the “Nanum” perfect for small gardens, which has dimensions of around one meter in height and one and a half meters in width and the variegated which is instead as large as the Pittosporum tobira and certainly more delicate, but can resolve points a a little dark with an original solution and with the wonderful characteristics of the original plant already described.

In the kitchen:
