The clear crisp flowers and glossy green leaves of vinca are so perfect you may be tempted to rub them to see if they are real. Also known as periwinkles, vincas are useful in borders, flowerbeds, rock gardens and containers and provides instant color wherever it grows. They come in a wide variety of colors from white, different pinks and lavender. Vinca is drought tolerant and requires almost no maintenance to keep it looking terrific. It performs best if you water the plants whenever the top inch or so of the soil feels dry to the touch. Take care not to overwater this plant; it's easily susceptible to root rot.
Keep potted vinca blooming well by fertilizing regularly with any general-purpose garden fertilizer. If you have good or average soil, you typically don't need to fertilize vinca growing in gardens and landscapes. It doesn't require deadheading, or the removal of faded flowers, to continue blooming, making it a wonderfully low-maintenance annual flower for sun.
