FLOWER BULBS

The nursery’s main product was initially Narcissus bulbs.
Today, greenhouses, shade netting and open fields are used to grow several varieties of Narcissus from the Tazetta group, Ornithogalum dubium and thyrzoides, Ranunculus, Scilla peruviana, Leucojum aestivum, Allium silver spring and others.
    What began with Narcissus has expanded into a wide portfolio, including several Tazetta varieties, Ornithogalum dubium, Ranunculus, Scilla, Leucojum, Allium, and more. Asa Flower Bulbs was the first to cultivate Ornithogalum dubium commercially, and remains the world’s primary supplier, exporting to Europe, the U.S., Asia, and South America.

    With over 50 years of expertise, the nursery continues to develop new varieties through careful breeding and selection — combining tradition, innovation, and global reach.

    ENDLESS
    FIELDS

    Our connection to Ornithogalum dubium runs deep. Years ago, we began experimenting with this unique South African species, learning how to adapt it to commercial cultivation. Since then, it has become one of our signature varieties — known for its bold color, graceful structure, and dependable performance. We take pride in being among the first to help bring dubium into homes and gardens around the world, and continue to refine it season after season.
