These are some of the new perennials in my garden, I finish off the landscape with double-sided castle brick edging. Snapdragon has lots of blue-lilac snapdragon-like 0.5" flowers. It is not deer resistant, but it's heat tolerant. Can you use the Chaenorrhinum seeds to grow a new plant?
Smaller deer resistant plant with little yellow flowers, the leaves make a woolly mass 1-2" high, foliage is scented when crushed. Good part is it only needs minimum care, spread quickly in poor loose soil, but will decline in appearance in humidity. It is perfect for rock garden, or in pockets on a stone wall. It can be used as groundcover with interesting texture.
