Hi, thank you for watching! As a general guideline, most lupins are tolerant of temperatures down to about 20°F (-6°C) once they are established. Typically you should wait until the danger of frost has passed in your area. In Zone 7, this generally means after the last expected frost date, which can vary depending on your specific location! Generally, if they have a couple of their true leaves, you should be okay to plant out. Hope this helps.
Thank you for your videos, they're so brilliant and helpful❤❤❤
How long do you keep them in those pots before planting into the ground?

Would love a field of lupus in Maine
They create beneficial soil so growing them in a field will make the soil rich and healthy.
My seedlings are about 4 inches tall. At what temp are they hardy to? I'm in zone 7 & after hardening off, when should I plant out?
