Assuming you can recognize what species you have, and you feel confident it’s an angustifolia (or you’re prepared for the more bitter taste of an intermedia), then yes! (See above for our recommendations against eating other lavender species.) Dried bud is the best for cooking with, though fresh lavender flowers can absolutely be used for garnish or to add a pop of color to a lavender drink.
If you aren’t sure of the species you’ve got, or you don’t have lavender in your yard, don’t fret – we sell our culinary lavender in a jar, a grinder, and even in bulk. So no matter your price point (or recipe needs), we’ve got you covered.
