See my little green friends?
My rose bed is planted with other things such as parsley, fennel, agastache, lavender, and Russian sage
in order to attract butterflies, bees, and hummingbirds because they are such good pollinators. Interestingly, the caterpillars have a very distinct preference for either fennel or parsley, depending on the variety of caterpillar. Monarch caterpillars love the fennel, as you can see in the photo.
