Allyson Heather (Cuphea hyssopifolia 'Allyson') Allyson Heather is a compact, finely textured subshrub bearing masses of small lavender-purple flowers from spring to frost. Its mounded habit and glossy, heather-like foliage shine in borders, containers, and warm-climate beds. Distinctive Features Prolific, self-cleaning blooms cover the plant for an extended season, attracting pollinators without deadheading. Dense branching and tiny leaves create a neat, uniform mound that holds color and form in heat. Growing Conditions Sun Exposure: Full sun to partial shade, with afternoon shade in hot climates. Soil: Well drained, moderately fertile soil; amend heavy clay for drainage. Water: Keep evenly moist to establish; moderate water thereafter with brief drought tolerance. USDA Hardiness Zones: 9 to 11. Mature Size: 1 to 2 ft tall and 1 to 2 ft wide. Ideal Uses Focal Point: Continuous bloom and fine texture anchor small-space plantings. Edging: Low, tidy mounds define paths and bed lines. Containers: Reliable season-long color in porch pots and window boxes. Pollinator Gardens: Nectar-rich flowers support bees and butterflies. Bedding Displays: Uniform habit suits mass plantings in warm sites. Low Maintenance Care Watering: Water deeply, then allow the top inch of soil to dry before the next cycle. Pruning: Shear lightly once or twice in the season to refresh shape and promote rebloom. Fertilizing: Feed monthly in spring and summer with a balanced, dilute fertilizer. Mulching: Apply a 1 to 2 inch mulch layer to conserve moisture and suppress weeds. Notes: Frost sensitive; grow as an annual in cool climates or overwinter indoors. Why Choose Allyson Heather? Long Bloom Window: Flowers steadily from spring through frost without heavy grooming. Heat Ready: Performs well in summer conditions with minimal stress. Compact Form: Neat mounds fit tight spaces and formal designs. Pollinator Friendly: Small tubular flowers attract beneficial insects. Versatile Use: Equally effective in beds, borders, and containers. Plant in morning sun with light afternoon shade, provide sharp drainage, and shear lightly midseason to keep the habit dense and flowering.
