Welcome, Alex! We look forward to seeing pictures of your garden. Your description of your surroundings sounds breathtaking! The topography here is hilly and has been a challenge for us, too. We live in the foothills of the southern Appalachians. We have had to build terraced beds on hillsides for our daylilies. We have to make the best of what we have. Sounds like you have, too. Can't wait to see it through your pictures!
We also have learned much from the knowledgeable folks here. This forum is a great place to learn and share.
