Pair the Astra White with other plants with white flowers for a monochromatic look, or mix and match the Astra White with colorful companions. The blooms support pollinators like bees and butterflies, but the Balloon Flower is deer resistant. Grow the Astra White Balloon Flower in zones 4 through 9.

Feed the Astra White Balloon Flower every two weeks using a balanced, water-soluble plant food. Deadhead the plant to encourage another flush of flowers. Removing spent flowers allows the plant to redirect energy into new bud growth. Trim all growth to ground level after the last of the flowers fade.
