Bidens aurea Hannay's Lemon Drop (1lt)

Bought back by the Compton, d'Arcy and Rix botanical expedition to Mexico in 1990 this lovely and hardy form of Bidens has particularly large lemon yellow flowers with broad white tips to the petals. It grows to around 1.2m high x 60cm wide and seeds freely.  An lovely addition to any border in well drained soil in sun. Choice!
