Thalia geniculata Photograph June 22. Moore Farms, Lake City, South Carolina. More dramatic, taller and without the pest problems but similar to giant canna’s. Flag adds tropical drama to pots, bogs or any garden waving it’s arrow shaped leaves and purple flowers above head. Why isn’t it used everywhere? Flowering Time: Mid-June through Summer. Flowers are interesting but this is primarily a foliage plants. Foliage: The dull green leaves are held like flags on tall, brilliant stems. It reaches 10 feet tall. Stunning stems! Growth Rate: Fast enough to be used as an annual. Ultimate Height: 10 feet.
Special Care: Plant in moist spots, with rich soil. Will even grow at the edge of a pond. Does not tolerate drought. This will seed itself in-- new plants come up near by. In harsh winters, it may die, but the seeds still come back. May get grasshopper damage in later summer. Gardening Tips: Plant right near a walkway, or in a pot to appreciate the towering leaves and red stems. Cut off lower and small leaves to show off the stems. Collect seeds to spread around in your garden. Sun to light shade. Suggested Combinations: Nice with low grasses and fine textured groundcovers ferns. Try it behind a medium sized shrub to add summer height and textural interest. Nice erupting from a pot or pond of water lilies.
