White flowered hellebores, jack-in-the-pulpits, hyacinthoides 'White City', and Camassia leichtlinii 'Alba' (I think this plant reverted from the overpriced 'Semiplena').   Stunning arrangement of greens and whites. 

Japanese maple branch and a couple of Smilacena racemosa.   Long graceful lines and arches.   Good color contrast with maroon and green maple leaves against bright green smilacena.   Texture contrast is most noticeable in long vase like.

Japanese maple branches, Siberian iris, wall iris, columbine, Spanish bluebells.    Good complimentary colors.
