Callie® 'White' Calibrachoa

Callie® ‘White’ is a trailing calibrachoa with pale, bell-shaped flowers that bring a clean light note to containers and garden edges. Its compact vertical growth and spreading stems make it especially useful in hanging baskets, window boxes, and mixed planters. ## Flowers and habit [Syngenta’s Callie® White profile](https://www.syngentaflowers.com/emea/nl/product/flower/70052153) lists it as Calibrachoa hybrida with white flowers, trailing growth, part sun to full sun exposure, spring and summer flowering, and a series size of 4–8 inches tall by 12–16 inches wide. The [RHS profile](https://www.rhs.org.uk/plants/227197/calibrachoa-callie-white-cal-white-callie-series/details) records ‘Cal White’ and ‘Cal Wiiten’ as synonyms for Callie White. The RHS also describes calibrachoas as tender perennials commonly grown as annuals, with a mostly trailing habit and trumpet-shaped flowers over a long period. ## Siting Grow the plant in a bright position; part sun is useful in hot areas or where container soil dries quickly. Callie’s spreading stems can trail over the edge of a basket or soften the rim of a pot, while a row of plants can brighten a sunny border. Syngenta’s [Callie culture guide](https://www.syngentaflowers.com/ams/sites/g/files/kgtney2381/files/media/document/2025/09/29/culture_vegetative_calibrachoa_callie_2025.pdf) recommends full sun and notes that production media should dry between irrigations. ## Maintenance Water when the potting mix starts to dry, and make sure containers drain freely. The [RHS recommends regular deadheading for Million Bells](https://www.rhs.org.uk/plants/120084/petunia-million-bells-series/details); remove faded flowers for a tidier display, or leave them if the basket remains neat. Pinch or trim a few long stems if the plant becomes uneven, particularly in a mixed basket.
