Deer browse regularly here, coming in from the wooded areas all around us. They have Never even snipped our lavender. We have 2 areas, one in front , and one in back with a total of 8 plants. We have had the plants for about 10 years. The bees love them and buzz like crazy when the lavender blooms from late June to late July. The bees never bother with us. I have learned that deer avoid most herbs, strong scented plants, and greyish leaves. That would be lavender.
