Certain plants thrive in the transitional period between summer and winter. These Indian summer bloomers unleash a final floral display just as many other plants enter dormancy. While Indian summer only lasts a few weeks, proper care allows Indian summer plants like alstroemeria to survive and even flourish through winter’s grasp.

Caring for Alstroemeria Through Winter

Of all the Indian summer plants, few bloom as vigorously or lend such vivid color as the alstroemeria. Often called the Peruvian lily, alstroemeria bears elegant clusters of pink, orange, red, purple, yellow, or white blooms. As a perennial, the alstroemeria returns year after year when cared for properly.

To help your alstroemeria not merely survive but positively thrive in winter:

• Cut back the foliage after the plant becomes dormant in late autumn. This prevents disease and helps the plant conserve energy.

• Apply a 4-6 inch layer of mulch around the base to insulate roots from extreme cold. Shredded leaves, bark chips, or compost work well.

• On extremely cold nights, cover plants with frost cloth or an inverted bucket to protect from freeze damage.

• Water sparingly during winter dormancy, providing just enough moisture to keep roots from drying out completely.

• Divide overgrown clumps in early spring to rejuvenate the plant’s vigor.

Growing Alstroemeria as a Potted Plant

While traditionally grown in gardens, alstroemeria also thrives in containers when given proper care:

• Select a pot at least 12 inches wide and deep to accommodate the plant’s tuberous roots.

• Use a well-drained potting mix and include pebbles or other drainage material at the base of the pot.

• Move the potted plant to a sheltered area like a covered porch or unheated garage once winter arrives.

• Water sparingly over winter, taking care not to oversaturate the soil.

• Apply liquid flower fertilizer every 2-3 weeks during the active growing season for abundant blooms.

Other Indian Summer Plants to Enjoy

While the alstroemeria steals the show, other plants join the display of color in autumn:

• Ornamental peppers – Mostly grown for their vivid fruit, ornamental pepper plants also produce delicate white blooms in fall. The peppers persist on the plant even after frost.

• Marigolds – These classic bedding plants bloom until hard frost. Marigolds come in a rainbow of colors including red, orange, yellow, white, and multi-colored varieties.

• Chrysanthemums – Available in a staggering range of shapes, sizes, and colors, chrysanthemums unfurl their flowers until freezing temps shut them down. They make excellent cut flowers.

• Asters – Closely related to the daisy, asters produce abundant single, semi-double, and fully double blooms in purple, pink, red, white, and other shades. Deadheading spent flowers encourages re-blooming.

• Sweet alyssum – This dainty annual features clouds of tiny white or purple flowers from early summer into fall. It thrives in light shade and releases a delicate, honey-like fragrance.
