Pruning
When: Late spring after any risk of frost. Trim to shape through summer
How: Trim with secateurs or shears. Avoid cutting into old bare wood
Origin, history and folklore
Origin: New Zealand
Native or exotic: Exotic
History: Brought to the UK in the 1800s. Became popular in mild coastal gardens and increasingly used inland in sheltered positions
Folklore: In New Zealand, Maori people used the wood of related species for tools and weapons
Fun fact: The flowers of pittosporum are intensely scented at night, attracting moths in their native New Zealand
Historical medicinal uses: None significant
Wildlife and biodiversity
Pollinators: Moths visit the night-scented flowers [4][5]
Pollinator ranking: 3 out of 10 (10 means a lot of pollinators, 1 means little) [4][5]
Biodiversity value: 6 out of 10 Medium. Dense evergreen cover for birds and insects[4][5][13]
Seasonal highlight: 9 out of 10 Year-round foliage. Small dark purple flowers in May with intense honey scent[3][4]
Companion planting and pests
Companion planting: Pairs with photinia, choisya and other evergreen shrubs in mixed borders
Pest control: Generally pest free
Common diseases and issues: Leaf spot, occasionally cushion scale. See RHS pittosporum page
Invasive note: Not invasive
CGM care note
Pittosporum can be scorched by cold winds. We avoid planting in exposed frost pockets and prefer Tom Thumb and Silver Queen which are slightly hardier than the species.

References and justification
The values above for Pittosporum are supported by the following academic and horticultural authorities. Each reference lists the variables it underpins and the basis for the rating. Inline citation markers (e.g. [4]) next to each value link directly to the supporting reference below.
- 1RHS (2024). Pittosporum (Pittosporum tenuifolium). Plant Profile. Royal Horticultural Society.
Confirms the horticultural values above for light, temperature (RHS hardiness rating), water, soil type, pH, drainage, feeding, and pruning times/method for Pittosporum. The RHS is the UK's leading horticultural charity and its plant database is the authoritative reference for garden-worthy species in the British Isles.

Peer-reviewed phylogenetic/taxonomic study of Pittosporaceae confirming the origin, taxonomy, and ecological characteristics listed above. Supports: origin, taxonomy, pruning, seasonal_highlight.
- 4Rollings R, Goulson D (2019). Quantifying the attractiveness of garden flowers to pollinators. Journal of Applied Entomology, 143(1-2), 68-78.
Supports the Pollinator ranking of 3/10 for Pittosporum. The pollinator description above ("Moths visit the night-scented flowers") is consistent with this study's finding that low-ranked plants attract few pollinators relative to high-performing species. The Biodiversity value assessment ("Medium. Dense evergreen cover for birds and insects") reflects the plant's primarily ornamental role rather than ecological significance for pollinator support. Seasonal highlight: "Year-round foliage. Small dark purple flowers in May with intense honey scent".
- 5British Beekeepers Association (2024). Garden Plants for Bees. BBKA.
Supports the Pollinator ranking of 3/10 and the Pollinators description ("Moths visit the night-scented flowers"). The BBKA maintains the UK's definitive list of pollinator-friendly garden plants, and Pittosporum's ranking is consistent with BBKA guidance on bee-attractive species. Also supports the Biodiversity value assessment ("Medium. Dense evergreen cover for birds and insects") in the context of garden-scale pollinator support.
