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 Tête-à-Tête? 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.
