Shade Plants for Drier Gardens

Although nothing grows is complete darkness (plants will etiolate, or weirdly stretch though) except for some parasitic plants, these plants will hold their own in many shade cursed areas in your garden. 

Aspidistra elatior

Commonly called the "Cast Iron Plant" for good reason; this slow growing but hardy Taiwanese native can take all kinds of abuse including abysmal light levels and infrequent watering (once established). 


Pronounced like 'calliope', this Chinese native thrives in bright shade to partial sun and moderate water -but will survive a moderate dry spell no worse for the wear after it has been established for at least a year or two. In part sun you can expect them to flower with either white or blue spiky blooms, but if they are planted in mostly shade, then they probably will not. 

 Mondo Grass

Ophiopogon japonica, commonly called 'Mondo Grass',i s a lily-like ground-cover that looks kind of like grass if you like lumpy lawns. It is, however, a good ground cover plant for shady areas and, once established (a process which can take some time), can tolerate short to moderate periods of drought. Pictured above are standard sized and dwarf Ophiopogon japanica. 


Nandina, a dwarf variety, growing in the shady part of the entrance walk at the Arboretum.

Nandina, commonly called 'Heavenly Bamboo', is an ubiquitous element of many Southern California gardens for a good reason; it is incredibly tolerant of low light, low water and low maintenance. Also a Chinese native (are you noticing a trend here?), some people worry about the toxicity of its berries to cats and Cedar Wax Wings -however in low light it tends not to produce as many (if any) berries as in full to half day sun. 




Clivia x cyrtanthiflora
Hailing from the Southern parts of Africa, this strap leaved, winter and spring flowering plant is tough. Although it does enjoy water when it's blooming, when it's not it can go two weeks or more between watering. There are several different varieties including one with a yellow flower. Sometimes you will plant Clivia and it has a hard time blooming. The secret is to plant them in bottomless pots or very close (less than a foot) from each other. For some reason being crowded seems to induce more bloom. 


Asparagus densiflorus 'meyerii'. 
Not the one you eat but the ornamental kinds like A. densiflorus 'meyerii' and A. aethiopicus (syn. sprengeri). Once established these hardy plants may be hard to control, just remember that they can spread via bulbs that they copiously produce underground. 


Once established these Hibiscus family members with the unfortunately misleading common name of "Chinese Maple" are extremely hardy in some fairly shaded areas once they are established (this I know from personal experience -I had one in a completely shaded area of a house I once had and it would not die no matter how badly I ignored it).  It comes in low growing and somewhat vine-like bushy varieties, the latter which have proved themselves survivors. 


Mahonia oiwakens subsp. lomariifolia

Mahonia repens
This group of hardy shade loving plants is native to the west coast of the United States and Asia and is one of the few plants to produce yellow flowers in the shade. Mahonia repens is a low growing ground-cover whereas Mahonia oiwakens subsp. lomariifolia is tall (up to 6-7 feet) and beautifully lanky. 


Variegated Carrisa

Dwarf and standard C. macrocarpa
This African native not only is an excellent dry area part shade to bright full shade ornamental, its ripe berries are edible! Several varieties are available including a dwarf and variegated type. What's the drawback to its seeming perfection? It is somewhat frost tender, and can experience considerable (though recoverable) die-back in cold years. 

Amaryllis and Amaryllis Hybrids 

Amarygia hybrids, a cross between Brunsvigia and Amaryllis. 
 Commonly called 'Naked Ladies', these South African bulbs produce beautiful pink blooms on stalks with no foliage in the hottest part of the summer, usually mid to late August. They will reliably bloom in bright shade, filtered sun, or even half day to full sun.


Various species and varieties of Sansavieria. 
Ultimately hardy, these African natives thrive on neglect -just don't water them too much. They grow in half day to full sun, but will gracefully tolerate (and even thrive) in filtered sun to bright shade.
