Few perennials are as striking or as storied as the iris. Known for its sword-like foliage and intricate, frilly blooms, iris brings a sense of elegance and drama to any garden. While the name covers a broad genus with hundreds of species, most New Jersey homeowners are familiar with bearded iris, which blooms in late spring, or Siberian iris, which adds a graceful texture in early summer. With cultivars in nearly every color imaginable, iris offers landscape designers and DIY gardening enthusiasts both versatility and flair.
Iris generally thrives in sunny locations with well-drained soil. Most iris varieties grow between 1 to 3 feet tall and work well in borders, near walkways, or as a standalone focal point. In terms of care, iris is relatively low-maintenance once established, though bearded iris should be divided every 3–4 years to maintain bloom vigor. With proper spacing and sunlight, it will reward you with strong vertical structure and show-stopping color year after year.
