Buttercups are also known by their botanical name Ranunculus . The peony multi-petaled type flowering blooms are extremely vibrant in color and very showy. Good as cut flowers in bouquets or for small pots. Easy to grow and are deer resistant. Ranunculus bulbs are widely available at retail nurseries and mail-order catalogs in mixed colors. However ranunculus in single colors are unique and caught our eye as they make for striking color displays in the garden. We have identified this color to be special.
