What a wonderful collection! Double Early Tulips combined with a blue surface of Grape Hyacinths! It almost looks like the large flowering Double Tulips are taking a swim in a blue sea of Grape Hyacinths (Muscari Armeniacum). This collection has great naturalizing potential. We ship top-size bulbs for optimal performance.
