Do you want to grow lemon verbena seeds in Illinois, but don’t know when to start them?
Starting lemon verbena seeds is not as easy as it seems.
- Lemon Verbena Seeds must be consistenly watered, receive at least 8 hours of sunlight a day, & be kept at room temperature of at least 70 degrees Fahrenheit.
So if you don’t consistently water them they won’t germinate. If they aren’t in a room that is at least 70 degrees Fahrenheit they won’t sprout. And if it receives 8 hours of sunlight the plant itself won’t grow.
- Because Illinois’s growing season is not long enough, lemon verbena seeds cannot be sowed outside and should only be started indoors.
Because of this, I’m going to teach you the ideal time to start lemon verbena seeds indoors in Illinois:

When to Start Lemon Verbena Seeds Indoors
Depending on the type of lemon verbena, it takes roughly 70-84 days (10 to 12 weeks) to grow lemon verbena from seed indoors before you can transplant them into your garden.
The approximate date of when you should start your lemon verbena seeds indoors can be found by:
- Finding the last average frost date HERE
- And then subtract 84 days from it
You can also find the average last frost date for most major cities in the below chart that I have created:
To help ensure the greatest success of your lemon verbena seeds germinating you should:
- Use a heat mat to ensure the gardening pot remains at 70 degrees Fahrenheit
- Use a grow light to control how much light your lemon verbena seeds receive
- Water your seeds with a spray bottle to ensure your seeds are not overwatered
It should also be noted that you will not want to introduce your lemon verbena plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bear vegetables.
