More About Vinca ‘Titan™ Polkadot’

Vinca ‘Titan™ Polkadot’ is a distinctive member of the Titan Series, known for its oversized blooms and eye-catching color pattern. The crisp white petals paired with a contrasting pink eye create a lively, classic vinca look that reads clearly even from a distance.

Plants maintain a tidy, mounded habit with excellent branching, making them well suited for mass plantings where uniformity and visual consistency are important.

Why We Like It (Our Trials)

In trials, ‘Titan™ Polkadot’ delivered steady flowering and clean foliage through prolonged heat and dry conditions. Plants remained uniform and well-shaped without stretching, even in exposed full-sun locations.

We value it as a high-contrast option within the Titan Series when bright, cheerful color is needed without sacrificing durability.

Titan™ Polkadot vs. Other Vinca

Titan™ Polkadot is the most playful option in the Titan™ Series, defined by its bold eye pattern rather than solid color. Compared to Titan™ Pure White, it adds contrast and visual movement instead of a clean monochrome look. Against Titan™ Icy Pink, it feels more graphic and energetic. Despite the pattern, it maintains the same uniform habit as the rest of the series. This makes it both expressive and reliable.

Compared to the Cora® Series, Titan™ Polkadot emphasizes scale and structure, producing noticeably larger blooms on upright, well-supported plants. Cora® Cascade Polkadot, by contrast, prioritizes trailing growth and movement, creating a lighter, more playful presence in containers. The Titan form reads bolder and more intentional in beds and borders, while the Cascade version feels relaxed and expressive. This difference makes Titan™ Polkadot better suited for structured plantings, with Cora® Cascade Polkadot excelling where flow and motion are the goal. I use Titan™ Polkadot when I want a pattern without sacrificing the upright structure.
