I absolutely love Lupines, but no matter what I do, mine seem to think they're annuals. I'm in either zone 5 or 6, and they definitely should do well in this zone. Last winter was our mildest in over 100 years. Still, my Lupines didn't survive. What on earth could I be doing wrong? I seem to have a fairly green thumb except for this one plant!

Wish I could help you but I've had no luck with them either in zone 5.

Maybe grow them only on the southside, or in some other slightly warmer and protected micro-climate?

I'm glad it's not just me, and I wish you could help me, too.

I've tried them in various different locations. I'm wondering if it has anything to do with how deep I'm planting them or with the soil. Do they require a certain kind of soil?

You need low pH soil. Soil supplemented with aged manure is good, and it probably helps to add a little more compost each year. Do you live in a high pH area? If so it will take more attention than normal. And also remember that cement tends to leach a little lime into the areas next to it, raising the pH.

Not sure if this information can help you in any way but I have never planted lupine, yet they are all over my property, multiplying year after year. I am in zone 5 and it seems that the seeds from the current plants are spread by the birds and grow. These are the purple colored ones. I had tried a pink lupine plant but it did not survive. I have collected the seeds from the lupine flowers (once they are dried up and before the birds get to all of them) and given them to my daughter, for whom they grew.

That's some great advice. I really don't know for sure about our soil, but that one thing could be what's causing the problem.

I wonder how it would work if I started them by seed. I know I could buy seeds. Would this be a good time of the year to try planting them?
