Ranunculus acris Citrinus v Sulphureus

[mark smyth]

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?

[ranunculus]

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

[mark smyth]

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.

[mark smyth]

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.
