When thinking deer resistant plants and flowers, several come to mind. None are guaranteed, as a hungry deer will eat whatever is available. However, there are options that are they are less likely to try. Deer tend to stay away from more fragrant and prickly plants and their instinct keeps them away from poisonous.
Lavender is also a great choice for our area as it requires full sun and well drained soil. A perennial shrub, up to three feet tall and four feet wide, lavender is not only beautiful, but smells heavenly too. Placing lavender along a walkway or in a garden with a seating area allows the most benefit from this beautiful multi-purpose plant. Dried lavender blooms can be used as a seasoning in the kitchen, edible garnishments and brewing teas. The darker the blooms, the more fragrant and intense in flavor it becomes.
Purple coneflower is as lovely as it is tough. This perennial is so easy to grow in any sunny spot. It will bloom through summer into the fall, drawing butterflies and birds. It is low maintenance, spreading easily and is not bothered by pests. Its daisy looking flowers make it a great choice if you enjoy cut flowers brightening your home.
