Japanese pagoda tree
A large legume tree from China that flowers in August and September, later than almost any other temperate tree, and produces a substantial nectar flow at the thinnest point of the year. It is planted widely as a street tree, which makes it one of the more useful pieces of urban forage that nobody planted for that reason.
Caution
The seeds and pods contain cytisine-related alkaloids and are toxic if eaten in quantity. This does not affect the nectar or the honey.
Value to bees
- Nectar
- High
- Pollen
- Moderate
- As a honey crop
- Minor honey crop — a surplus only locally or occasionally
- Which bees, and why
- Worked heavily by honey bees and bumblebees in August and September. As a widely planted street tree it is one of the more significant unintentional urban forage sources in European and American cities.
- Worth knowing
- A good late nectar source and moderate pollen, at a genuinely useful point in the season.
Flowering
- In flower
- July to September (northern hemisphere)
August and September in most of Europe, and among the latest-flowering temperate trees.
- When nectar flows
- Substantial from a mature tree, and valuable specifically for arriving after the main summer flows have ended.
- Year-to-year variation
- Trees must be mature to flower well, which takes a decade or more. Where they are planted in numbers as street trees the collective flow can be considerable.
Growing it
- Conditions
- Full sun, tolerant of drought, pollution and compacted urban soil, which is why it is planted along streets.
- Size
- 15-25 m tall with a wide crown.
- Native range
- China and Korea, despite the common name. Planted widely as a street and park tree across Europe, North America and Asia.
- Suits
- Large gardens
- Takes ten to fifteen years to flower, so plant it for the long term.
- Exceptionally tolerant of urban conditions — drought, pollution and root restriction.
- The fallen flowers and pods make a mess on paving, which is the usual complaint against it.
What it looks like
A broad spreading tree with pinnate leaves and large loose panicles of creamy-white pea flowers in late summer, followed by distinctive constricted green pods like strings of beads.
