Anyone referring to a flower named 'Buttercup' elicits all kinds of confusion. Are they referencing a Ranunculus, using a generic term for jonquils that bloom freely in the South, increasingly as an alias for One of the several daffodils registered under that name? We offer the historic Rev. Engleheart jonquilla 'Buttercup', a strong grower with large flowers more reminiscent of a historic small cup. Rare. Brings intense happiness to the gardener. Smells good.
