More About Cuphea ‘FloriGlory® Diana’

Cuphea ‘FloriGlory® Diana’ is an improved Mexican heather selection prized for its exceptionally dense flowering and tidy, compact habit. The small lavender-purple blooms appear continuously along fine-textured foliage, creating a soft, cloud-like look that lasts from late spring until frost.

As part of the FloriGlory® series, ‘Diana’ was bred specifically for uniform growth, improved branching, and higher flower count. Unlike older Mexican heather types that could become loose or uneven, this variety stays neat and well-shaped with minimal maintenance.

Why We Like It (Our Trials)

In our trials, ‘FloriGlory® Diana’ has been extremely dependable through heat, humidity, and long summer conditions. It fills in evenly, maintains a clean mound, and continues flowering steadily without the need for deadheading.

We especially appreciate its versatility. It works beautifully as a low edging plant, a filler in mixed containers, or a mass planting where its fine texture and consistent bloom create a polished, cohesive look. Bees and small pollinators visit regularly throughout the season.

FloriGlory® Diana vs. Other Cuphea

‘FloriGlory® Diana’ is a more controlled and compact alternative to larger-growing selections like Vermillionaire® and Hummingbirds Lunch. It maintains a tidy habit that works well in containers, distinguishing it from the looser growth of ‘Bat Face’. While it doesn’t match ‘Vermillionaire®’ in sheer bloom count, it offers better symmetry and less legginess. Its refined structure makes it especially suitable for retail-ready plantings.

Compared to FloriGlory® Maria, ‘Diana’ often reads slightly stronger in branching and overall balance, though both share similar breeding goals. When placed next to David Verity, ‘Diana’ appears more compact and intentional, with fewer gaps in the canopy. Unlike Mexican Heather, it still provides showy individual flowers rather than texture alone. ‘FloriGlory® Diana’ fits best where polish and predictability are essential.
