Nierembergia spp.
Cupflower is a tender perennial, which is grown and used as an annual in New Jersey. This genus offers several species to choose from, and many cultivars are available offering various shades of blue and purple. Perky, cup-shaped flowers bloom May to frost. Cupflower prefers consistently moist soil, and is not able to tolerate heat and humidity. Use mulch in your garden beds to keep the soil moist, and find a protected place along borders in your yard. Try planting Cupflower in your rock garden, mixed containers, and hanging baskets for a full season of enjoyment of this long-blooming plant.
