Impreza™ Formula Mix Impatiens

Impreza™ Formula Mix is a trade-named *Impatiens walleriana* product currently listed within Bill Moore & Company’s Impreza Impatiens offerings. PanAmerican Seed’s 2016 catalogue describes the Impreza® series as compact and well-filled, with historical series measurements of 6–8 inches high and 12–14 inches in spread. ## Selection and series history The current [Bill Moore listing](https://www.billmooreco.com/pricelist_print.php?vendor_no=548) names the exact Formula Mix selection but does not enumerate its component colors. PanAmerican’s [2016 catalogue](https://www.panamseed.com/documents/catalogs/14520_PASKieft_2016Catalog-LowRes.pdf) describes reduced upward stretch, good garden fill, and uniform finishing across the Impreza series; its dimensions are historical series-level context. ## Growing conditions The [North Carolina Extension Gardener Plant Toolbox](https://plants.ces.ncsu.edu/plants/impatiens-walleriana/) describes I. walleriana as a bedding plant often grown as an annual outside tropical climates. It prefers part to full shade and moist, well-drained, organic-rich soil. Partial sun is possible with adequate water, while excessive sun can scorch foliage; hot, dry spells can increase watering needs. ## Maintenance Keep the soil moist but freely draining and check moisture during hot, dry weather. If plants become leggy in late summer, NC State recommends trimming back the top third to encourage new blooms and refresh the plant.
