Hi Corey and welcome! So glad you found the migration route from DG
.
My gardens are heavy clay and some lilies have never done well here. In particular I am lucky to keep those lankongense hybrids for more than a year. They do not like being wet in the winter! These include Judith's Lace series, Chris North's hybrids and others. They may well do better for you in your sandy soil.
A few of us here like to grow lilies from seeds, and being a member of NALS gives you access to their seed sale. It is a very inexpensive way to acquire one of a kind lilies. Myself, I'm partial to those down facing lilies and I have grown a number of them from seeds.
I hope you have a camera and will post some photos come summer. Here in the Pacific Northwest we will have a long, dreary, wet winter so thinking of summer is a favorite pastime.
