Sun Zones 5, 6, 7, 8, 9 Red flowers
This selection of Painted Daisy is a great favorite with customers.

Early summer. bloom 2 ft. x 2 ft.

Shade, Part Shade Zones 4, 5, 6, 7, 8 Green White flowers
Tellima grandiflora 'Red' is a selection from one of our Pacific Northwest Natives. This is one of the earliest local natives that we introduced to our gardens. It has gently naturalized, weaving around other woodland treasures to give continuity to a bed. This form has red hints in its heart-shaped leaves and stems and pink in the small fringed flowers. The airy inflorescences create a pointillist pattern reminiscent of heuchera and tiarella flowers. Late spring to summer. bloom 32 in. x 12 in.

Sun, Part Shade Zones 5, 6, 7, 8, 9 10 Deep Pink flowers

Summer. bloom 12 in. x 12 in.
288-001 Teucrium scorodonia 'Crispum' 
Sun, Part Shade Zones 7, 8, 9 Greenish flowers
Because of its rhizomatous nature and the fact that it is evergreen, this makes a fine groundcover in dry woodland borders. Its gray green foliage is very distinct, the substantial leaves being dimpled and crimped along their borders with a little white visible from the underleaf in the crimping. The loose racemes of pale flowers seem almost an after-thought. Yet another added feature in favor of Teucrium scorodonia 'Crispum' is that deer seem to ignore it. Summer. bloom 10 in. x 12-15 in.
081-012 Thalictrum lucidum ( Shining meadow rue ) 
Sun, Part Shade Zones 5, 6, 7, 8, 9 Pale Yellow flowers
