Lavender comes in different colors and sizes, making it a perfect plant for nearly every garden. English lavender, for example, is a tough, hardy plant that is a reliable bloomer that requires little care or maintenance. Choose Phenomenal lavender for its adaptability to both very cold winters and hot, humid summers. It is also a go-to option for drying and use in potpourri. For gardeners with small spaces to fill, Hidcote lavender is just the ticket. Compact plants grow to only 12 inches tall, but still produce lots of fragrant, purple-blue flowers.
