Ajania

Ajania pacifica ( Silver & Gold Chrysanthemum )
A vigorous bushy subshrubby perennial native to Japan that can reach a maximum size of 2.5 x 5.5 ( rarely over 2 ) feet. It is usually found on the shoreline on Honshu Island in the wild. There are few better border plants to brighten up a drab autumn landscape. It also makes an excellent container plant and groundcover.
The attractive semi-evergreen leaves, up to 3 x 1 inches in size, are deep green edged silver above, woolly white beneath.
The golden-yellow flowers up to 0.7 inches in width are borne in clusters, up to 4 inches wide, during October, November and in mild years into December. The flowers attract butterflies and hummingbirds.
Hardy zones 4 to 9 in full sun to partial shade on any well drained soil. Very tough and drought tolerant. Cut back hard after flowering. Deer do NOT eat this plant.

Grewia

A genus of close to 150 species of trees, shrubs and vines that are mostly native to Asia, Australia and Africa. Some are hardy in temperate climates but most are restricted to the tropics.
The foliage on most is oval with finely serrated margins.
Most Grewias prefer full sun on moist, well drained soil.
Old plants can be renovated by hard pruning before growth begins in spring. Otherwise little pruning is needed however they can be tip pruned ( not sheared ) to keep them more compact.
Propagation can be either from half-hardened cuttings or seed.

Grewia biloba
A moderate to fast growing shrub, reaching up to 12 x 10 feet, that is native to central & eastern China & Korea. Some records include: fastest recorded growth rate - 3 feet; largest on record - 16 x 20 feet.
The deciduous ovate leaves are up to 5 x 4 ( rarely over 3 x 1.5 ) inches in size. The foliage is mid-green turning to bright yellow during autumn.
The creamy-white to yellow flowers are borne on clusters during late summer.
They are followed by small orange to red, two-lobed fruits.
Hardy north to zone 5 ( not fully tested in North America ) in full sun to partial shade. It is hardy in southern Michigan but in the Chicago area is typically a perennial rather than shrub after most winters. It has been known to tolerate as low as -22 F but does require hot summers thus growing poorly in much of western Europe and the British Isles.





Grewia occidentalis
A fast growing shrub to small tree native to South Africa. The largest on record is 26 x 15 feet though usually much smaller.
The leaves are up to 4 inches in length.
The flowers, up to 1.5 inches wide are light pinkish-purple.
The flowers are followed by purple-red 4-lobed fruits up to an inch wide.
Hardy zone 8 to 11

Muhlenbergia capillaris ( Pink Muhly Grass )
A long-lived, clump-forming hardy perennial grass reaching up to 5 x 6.5 ( rarely over 4 ) feet.
Native to southeastern North America ( from eastern Kansas to southern Ohio to Massachusetts; south to central Texas to Louisiana to south Florida ), it is endangered in the wild in Indiana, West Virginia, Connecticut, New Jersey and Maryland, and is extinct in the wild in Ohio, Pennsylvania and Massachusetts.
The fine textured foliage is wire-like and blue-green to deep green.
The foliage clump is topped from mid-August through October by pink cloud-like inflorescences up to 10 x 8 inches in size.. The flower inflorescences are exceptionally beautiful when backlit by the sun. Occasional deep irrigation during late summer will enhance autumn blooming.
Hardy zones 6 to 9 ( extinct western Massachusetts population was likely hardy to zone 5 ) in full sun on very well drained soil. It is not eaten by deer. Extremely drought, heat, salt and poor soil tolerant. Mostly found on sandy and rocky soils in the wild and does not need much fertilizer. Pests and disease problems are very rare.
Great for urban garden and against white stucco walls.
Also a great plant for drought plagued parking lot islands.
Cut plants to ground during late winter to make room for fresh new growth.

Muhlenbergia emersleyi 'El Toro' ( Bullgrass )
A very attractive, evergreen, clumping grass, reaching up to 3 x 4 feet. It forms a denser clump than Muhlenbergia rigens. The species is native to hilly oak woodlands in most of Arizona, New Mexico and western Texas.
The coarse foliage is blue-green. The leaves are wider than that of Muhlenbergia rigens.
The showy flower spikes are fluffy and rose-purple, eventually fading to tan.
Hardy zones 6 to 9 ( the species only hardy to zone 7 ) in full sun to partial shade on well drained soil. It is clay tolerant and very drought / heat tolerant. Soak weekly during summer during the first season, biweekly the following summer to establish new plants. Established plants can be soaked every 3 weeks. Deer resistant. Cut clumps back hard during early spring every other year to eliminate thatch.

Muhlenbergia lindheimeri ( Lindheimer Muhly Grass )
A moderate growing, perennial grass, reaching a maximum size of 4 x 5 ( rarely over 2.5 ) feet, that is native to the Edwards Plateau of Texas as well as northern Mexico.
The fountain-like foliage is blue-green. The foliage is deciduous and clumps are cut back hard during early spring.
The purplish, turning to silvery fountain-like plumes, up to 5 feet high, are borne during autumn.
Hardy zones 7 to 9 in full sun. Very heat, drought, clay, salt, alkaline soil, mediterranean climate and deer tolerant.

Muhlenbergia 'Pink Flamingo'
A narrow, upright, vigorous hybrid, reaching up to 5 x 4 feet. It is a hybrid between Muehlenbergia rigens and the Gulf Coast Muhly Grass.
The very narrow foliage is blue-green.
The soft pink flower spikes are borne during early autumn.
Hardy zones 6 to 10 in full sun on very well drained soil. It is extremely heat, drought as well as humidity tolerant, making it a great landscape plant for both the desert southwest and the southeastern U.S.
Great for the confined urban garden and against white stucco walls.
Also a great plant for drought plagued parking lot islands.
Deer resistant.

Muhlenbergia reverchonii ( Autumn Embers Muhly Grass )
A perennial grass, reaching up to 3 x 2 feet, that is native from southwest Oklahoma to northern Texas.
The finely-textured foliage is mid-green.
The flowers appear in a very attractive pinkish-red, haze during autumn.
Hardy zones 5 to 9 in full sun on very well drained soil including clay. It is extremely heat and drought tolerant, making it great for the inner city as well as suburban strip mall landscaping. Considering it's native range, it is very tolerant of the heat + humidity combination found in the southeast. It is highly deer resistant.

Muhlenbergia rigens ( Deer Grass )
A very attractive, fast growing, ornamental grass, reaching up to 5 x 7 ( rarely over 4 ) feet, forms a dense, evergreen clump of gray-green foliage turning to buff-tan during winter. It is native from northern California to central Texas; south into northern Mexico.
Hardy zones 6 to 9 in full sun to partial shade on rich, well drained soil. Extremely adaptable and very drought tolerant. It is not prone to pests or disease. Cut back hard every 3 years to renovate.
