Red and White. Giant Amaryllis are easy and thrilling to grow indoors, and a great gift for a child or the home bound person. Unlike many other amaryllis bulbs on the market, our large hybrid bulbs will produce two 18-24" stems, each bearing 4 or 5 huge, long lasting flowers that are over 8 inches in diameter. Ever grown an amaryllis inside the house? It's a snap. There can be rain, cold or snow outside, but all you do is water this "magic lily", and it zooms into growth. In just a few days, the stems arise, and in a few weeks the enormous flowers begin to open--huge lily blooms up to 8" across! It only takes 6 to 10 weeks from first watering to full bloom and you'll have a big show for over a month. Cooler fresh bulbs stored in our temperature controlled bulb storage rooms. Amaryllis bulbs stored in warehouses have a much shorter blooming period.
