Alonia™ Big Grape Angelonia angustifolia

Alonia™ Big Grape is an upright, mounding Angelonia angustifolia with large grape-purple flower spikes and narrow green leaves. Danziger describes it as an early-flowering, heat-tolerant ALONIA™ cultivar for containers and landscapes, with flowers that support pollinators. ## Landscape Use Repeat it through a sunny border, group it for a block of color, or use it in a patio container. The breeder lists typical dimensions of 14–16 inches high and 12–14 inches wide; the existing catalog measurements fall within those ranges. Its upright spikes rise above the foliage without the scale of a large shrub. ## Siting and Seasonal Display Provide full sun and fertile, well-drained soil that remains moderately moist. Angelonia tolerates summer heat and humidity and is often grown as an annual outside warm, frost-free regions. The [North Carolina Extension Plant Toolbox](https://plants.ces.ncsu.edu/plants/angelonia-angustifolia/) describes the species’ long summer bloom and moist, freely drained soil; [Oklahoma State Extension](https://extension.okstate.edu/programs/oklahoma-proven/plant-profiles/summer-snapdragon) notes its use in beds, mixed borders, and containers through summer and until frost. Flower color and timing can shift with climate. ## Breeder [Danziger’s Alonia™ Big Grape profile](https://www.danzigeronline.com/catalog/annuals/alonia-big-grape/) identifies the cultivar and reports an upright habit, large flowers, early flowering, heat tolerance, pollinator value, and pot/landscape suitability. [Ball Seed’s plant information](https://info.ballseed.com/PlantInfo/?phid=004905464052078) independently lists 14–16 inches high, 12–14 inches wide, and sun to partial-sun exposure. ## Maintenance Keep root-zone moisture even while plants establish and during extended dry weather; containers may need more frequent watering. Routine deadheading is generally unnecessary. Remove declining stems at season’s end, and replace plants after frost where winters are cold.
