This collection produces a sweep of 1 1/2" flowers in white marbled pink, rose, red and yellow, and 4 o'clock is about the time the striped, trumpet-shaped flowers open, suffusing the air with a sweet, orange-blossom scent. Plants attract hummingbirds by day and moths by night. Great for border or container. Plant in average, well-drained soil after last frost, and this annual will reward you with a summer full of colors.
