Thanks!
I have never considered having a planter by the door but it’s a wonderful suggestion.
I have Lavender and lemon verbena in the herb garden. Don’t have citronella grass but have lemon geranium which is supposed to repel mosquitoes.
I’ll have to hunt for the holy basil. Maybe get seeds. I’ve never seen it locally in nurseries.
There may be other sources that do just as well but I ordered the print catalog from this company in Charles City, Virginia and my mom was very happy with the plants she’s received. Not especially cheap, especially on the native species, but there aren’t too many places to get them. The link is to their list of insect repellent plants that they have in their nursery that they will sell and ship to you:

I went down the list of plants that are toxic to dogs and lemon verbena as well as citronella grass (lemongrass) are on it. I’ve used it myself on my dogs to no ill effect, however don’t let them eat it.
