    Everything looks fantastic. I am especially fond of eriongonums. You have some lovely specimens.

      Thanks Elaine. Eriogonums are wonderful and I’d love to grow more. Haven’t had much luck from seed, but occasionally get some cuttings to root. They are one of my favorites.

    I love every one of these flowering plants. We even have a couple of overlaps – Callistemon viridifolorus and Phlomis fruticosa (albeit not blooming on the same schedule). The Phuopsis reminds me of Pentas, although I like the form and foliage of your plant better. I love that Penstemon and the nodding onion Allium too.

    1. Botanica Chaotica

      I remember being surprised how early your Phlomis bloomed. Definitely a different schedule/environment. The Phuopsis is nice-looking early in the season, but gets all leggy right about now and doesn’t rebloom, although I haven’t cut off the old flowers to see if that helps. Sort of hoping it will reseed.

    Looking lovely. Penstemon pinifolius and the Erygiums and Eriogonums. The parking lot save is important food for some tiny pollinator–so it’s beautiful in its own way, too.

    Did you create a berm and then add rocks over the top? Healthy, happy plants–worth the effort.

    1. Botanica Chaotica

      Depends which rock garden, hb. Several rock gardens are berms of sand and gravel on top of our clay, but the back rock garden is all clay with rocks laid on top.

    I have never even heard of Phuopsis sylosa – it’s fabulous in its starry way! I’m a big fan of the buckwheats too – especially that little umbellatum. We had a big patch of it on the way into the office at Joy Creek, dotted with Agave parryi. If I ever move somewhere where I have enough sun, I will be sure to plant some.

    1. Botanica Chaotica

      It sounds like there was so much that I missed at Joy Creek. I was only there a few times before it closed and we never really had time to wander the gardens to see what was what. I enjoy seeing buckwheats out in the wild, but wow are they are to identify!

    A lot of wonderful looking plants that I mostly have not heard of. Some great rocks as well.

      Thank you Linda!
