We love this beautiful iris, with its frilly, deep blue and white petals and its luminous yellow throat that makes it light up from the inside. Magical! And since City Lights are re-blooming irises, you get to see them light up twice a year—they'll flower in late spring and then again in early fall. They'll grow up to 38 inches tall, so they're perfect for borders and as a backdrop. Make sure you plant the rhizomes in well-drained soil, give them lots of sun, and fertilize them after the first set of blooms has faded. Tip: Since irises bloom at different times depending on their size, combine several types together for an even longer blooming period. City Lights look great with Frequent Flyers! And, good news: they're deer- and rabbit-resistant.
