|what type of plant and/or shrub can be used in extreme shade, no sun ever or direct sun, no shade ever..|
|There are very few plants that will grow in both deep shade and direct sunshine so I'm wondering if you have two separate sites - one in deep shade and the other in full sunshine? If so, here are some plants for you to consider. Shade first:
The evergreen groundcover epimedium thrives in shade and this one is a tidy clumper, good for squeezing into crowded gardens. Its flowers are a combination of purple and white, and the new spring foliage is becomingly flushed with red. Cornus canadensis (unalaschkensis) Bunchberry; Partial to full shade, humus-rich soil. Spring flowers; bright red berries in summer. Grows 2"-10". Gaultheria ovatifolia (Slender Wintergreen); Adaptable, best in moist shade and acid soil. Flowers in late spring to summer. Evergreen. 4?8" tall. Linnaea borealis (Twinflower) Partial to full shade. Late spring flowers. Low (1") evergreen. Spreads readily by stolons. False Lily-of-the-Valley; Moist shade to partial shade. Spring flowers. Plant only where you want it to spread! 3? 12" Oxalis oregona (Wood Sorrel) Wet or dry shade. Spring/summer flowers. 2? 6" Vancouveria hexandra (Inside-out Flower) grows in sun to shade; flowers in spring. 4? 16" Adiantum pedatum (aleuticum), called Maidenhair Fern. Grows best in moist shade. Deciduous. Delicate, lacy fronds. 12?30".
