91. Autumn Snowdrop
Autumn flowering snowdrops are bulbous perennials that add color and interest to fall gardens. Many cultivars are artfully crafted with nodding white flowers consisting of outer petals that enclose inner petals and green to grey leaves. Snowdrops are worthy of their beauty, and several have earned the Award of Garden Merit from the Royal Horticultural Society.
Autumn Snowdrops are best planted in groups to create a compelling image. They are relatively easy to grow and fit perfectly in border fronts, woodland gardens, rock gardens, and naturalized areas.

This robust herbaceous perennial plant grows in upright clumps 4-7 feet tall. It blooms from midsummer in a profusion of bright golden petals with a contrasting pale green central disk that matures into a rich brown color.

94. Aztec Lily
Otherwise known as Sprekelia formosissima, Aztec Lily is native to Mexico’s rocky hillside. It is a member of the Amaryllis family, and the unique red flowers are simply irresistible and a bit reminiscent of the amaryllis. The large flowers that grow individually at the end of the sturdy but hollow cylindrical scapes are among its most distinguishing factors. Its flowering pattern is unique, but its foliage is similar to that of tulips or daffodils. After establishment, Aztec Lily does well in droughts, making them an excellent flower for drought-prone areas, although you’ll need to constantly water it during the growing season.
