Hmm, I'll have to look into those. I already have a couple of citron/citronella-scented plants - a couple of mints and one gum (a nice tree from the Eucalyptus family.) What other kinds are there?
So far, I have mints, wintergreen, rosemary, lavender, two Eucalyptus species, lemon bay and the lemon-scented gum. I've noticed some cedar seedlings sprouting in my bog pots this year so those will probably become an official part of the collection soon, too. I like them because not only do they have strong, attractive scents, but are also very colorful and have interesting textures to their leaves. I was inspired to start collecting these kinds of plants by teaching gardens. I read about one for the blind that was full of plants with various scents and textures, and I saw another on TV that was for kids with learning disabilities that featured edible plants with distinctive shapes and colors. I'm really interested in ecology and biology education, and I like the idea of using plants and gardening to get kids into science.
