Chameleon Indian Summer Calibrachoa

CHAMELEON® Indian Summer is a color-shifting calibrachoa whose flowers open in changing orange and yellow expressions as light and seasonal conditions change, with orange and yellow tones noted for Indian Summer by Monrovia. Its semi-trailing growth and long summer display make it useful in baskets and containers, where the changing mix of hues can be seen close up. ## Form and flowering Plant Source International lists this variety as an annual calibrachoa, 6–12 inches tall, with a semi-trailing habit. Tried & True describes color continuing through summer until the first hard frost, with flowers changing in response to light, day length, and other seasonal factors. Its cited width of 20–24 inches differs from PSI’s tighter 8–12 inch spacing, which is a planting spacing rather than mature spread. ## Siting Use a well-drained potting medium and provide full sun to partial shade. PSI lists part sun to shade, while Tried & True recommends full sun or partial shade; adjust exposure for local heat and light. The spreading stems make the plant suitable for hanging baskets and mixed containers. ## Maintenance Water when the surface begins to dry, but do not let the root ball dry completely. Tried & True advises regular feeding for continuous bloom.
