This evergreen hybrid has deeply veined, glossy leaves that grow up to 1 ft (30 cm) long. It's a beautiful plant even when not in bloom. But the star-shaped, snowy-white flowers that appear in summer are a sight to behold -and fragrant, too. Amazon Lily flowers resemble narcissus, featuring a cup in the center of each bloom, tinged with green. The flowers are about 3 in (8 cm) wide and grow in clusters on thick, upright stems that may need staking to hold them up. You can expect 3 or more flowers per stem.
