Thank you for your congratulations.
Fleur, I have tried two ways of growing Bidens ferulifolia : the first in partial shade under Nerium olander. In this place, it grows slowly, rather low, and blooms in a sporadic way, mainly when the weather is warm. The second way : in full sun all the days of the year (in due South), sheltered from the cold wind (The "Mistral") : then, it's blooming amazingly all the year, even the winter, with a lot of flowers, and forming higther plant. Unmistakably, it grows better in sun ...but need more wather for that ! (nb : in this place, it's in zone USDA 10a)
Mike, I'm going to try to propagate Epilobium canun 'Western hills from cuttings or to layer. If that walks (it's never win for me !), I send it to you. Thank you for the correct name of lantana montevidensis; I'm going to modify that.
