Definition
Meaning
A flowering shrub, scientifically known as Buddleja, that produces dense clusters of small, fragrant flowers which attract butterflies and other pollinators.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation ('бабочка куст'), which is nonsensical. The correct equivalent is the plant name 'буддлея' (buddleya).
- The word 'bush' does not mean the same as Russian 'куст' in all contexts; here it is accurate.
Common Mistakes
- Spelling as one word: 'butterflybush'. It is a compound noun, typically written as two separate words.
- Confusing it with 'buttercup' (a different flower) or 'butterfly weed' (a different plant, Asclepias).
