Titan-ium™ Mixture Vinca

Titan-ium™ Mixture is a raw-seed mix of the colors in the Titan-ium™ vinca series. Its upright, mounded plants flower from late spring through summer into late summer and provide a coordinated warm-season display in sunny beds, borders, and containers. [Breeder description](https://www.panamseed.com/Products/063709995003332/vinca-titan-ium-mixture/) ## Form and flowering The Titan-ium™ series has a branching, mounded and upright habit. Breeder specifications list mature dimensions of 14–16 inches tall by 10–12 inches wide; the catalog’s existing metric values are consistent with these approximate ranges. The mixture contains all colors in the series; individual flower colors vary among seedlings. PanAmerican notes that Titan-ium™ has high resistance to some aerial Phytophthora strains; resistance does not mean immunity.

UF/IFAS species guidance for Catharanthus roseus notes that plants tolerate dry conditions and should not be overwatered, while exact needs vary with site and cultivar. Plant after frost danger has passed and use in sunny borders, mass plantings, or containers where the compact flowering mound can be seen. [UF/IFAS species guidance](https://ask.ifas.ufl.edu/publication/fp112) ## Maintenance Water new plants while they establish, then let the soil drain between waterings. Reduce watering during cool or rainy periods and avoid persistently wet soil, which can encourage root problems. Remove damaged flowers or foliage as needed to keep the planting tidy; routine shaping is generally limited.
