Trinity Grace Diascia

Trinity Grace Diascia (Diascia barberae 'Trinity Grace') is an elegant, cool-season perennial that enchants with large, pristine white flowers carried on upright, wiry stems above a compact mound of bright green foliage. The generously sized blooms are notably larger than typical Diascia varieties, giving Trinity Grace a refined, airy presence that is equally at home in containers, hanging baskets, and the front of the border.

Grown from professional-grade nursery stock, Trinity Grace Diascia arrives with a strong, well-established root system ready to bloom prolifically in the cool temperatures of spring and fall. Its tidy, mounding habit and clean white flower color make it an exceptionally versatile plant — beautiful as a standalone specimen, as an elegant filler in mixed container designs, or as a soft, romantic edging plant along pathways and garden borders.

• Large, Pristine White Blooms: Notably oversized white flowers — larger than standard Diascia varieties — are produced abundantly on upright stems, creating an airy, refined display that brings cool, romantic elegance to containers and garden beds throughout the cool season.
• Cool-Season Powerhouse: Thrives in the mild temperatures of spring and fall when many summer annuals are not yet at their best, making Trinity Grace an essential plant for extending the garden's color season from early spring through late autumn.
• Compact & Container Perfect: A naturally tidy, mounding growth habit makes this variety ideal for patio containers, window boxes, hanging baskets, and front-of-border edging, where its white blooms brighten and lift any planting combination.
• Excellent Cut Flower Potential: Long, wiry stems bearing clusters of white flowers cut beautifully for fresh arrangements, adding a delicate, cottage-garden quality to bouquets and floral designs.
• Professional Grade Root System: This plant arrives with a healthy, well-developed root system that establishes quickly and delivers a reliable, generous bloom display throughout the cool growing season.

This 4" healthy live plant thrives in full sun to part shade with moderate, consistent moisture and good drainage. As a cool-season perennial, Trinity Grace Diascia performs best when temperatures range between 45–70°F and may go semi-dormant or decline in the peak heat of summer, often rebounding beautifully in fall when temperatures cool. It is suited to USDA Hardiness Zones 7–9 as a perennial and is grown as a cool-season annual in colder climates. Mature height reaches 10–14 inches with a spread of 12–16 inches. Deadhead spent flower stems regularly to encourage continuous bloom production throughout the season.
