Title: Ranunculus acris Citrinus v Sulphureus
Post by: mark smyth on November 28, 2010, 10:00:45 PM

Does anyone grow these two buttercups - Ranunculus acris Citrinus and R. acris Sulphureus.

Googling them they seem to be very similar. What's the difference?

In my experience, Mark ... absolutely nothing, apart from the name.

Just as I thought

Isn't R. acris the field buttercup of every farmer's paddocks? a really menace here and in my lawn. I can't imagine anyone choosing to grow it.

Yes R. acris grows in fields especially damp ones. I would have thought the pest in your lawn is the creeping buttercup R. repens that has lots of great looking cultivars over here.
