Common Names
Railliardia montana Mann var. robustior Sherff is commonly known as the Haleakal? silversword, robust silversword, or simply the silversword. Its Hawaiian name is ‘?hinahina.
Uses
Railliardia montana Mann var. robustior Sherff is primarily grown as an ornamental plant due to its striking looks and uniqueness. It is also used for medicinal purposes by Hawaiians to treat various ailments like respiratory problems, stomach issues, and joint pains.
General Appearance
Railliardia montana Mann var. robustior Sherff is a perennial herb that grows from a decumbent stem with fibrous roots. The plant can reach up to 80 cm in height and has long narrow leaves that are covered in silvery-white hair. The inflorescence is a dense cluster of yellow flowers that grows at the end of a long stalk. The silversword's most striking feature is its silver-sheened foliage, which comes from the dense covering of tiny hairs that reflect the sun's intense rays and protect the plant from dehydration and ultraviolet radiation. The plant is a prime example of adaptive radiation by which the plant community has evolved in Hawaii to occupy a diverse array of niches.
Light Requirements
Railliardia montana Mann var. robustior Sherff thrives in partly shaded to fully sunny areas. However, it prefers locations where it can receive direct sunlight for at least 6 hours per day. When grown indoors, providing bright and indirect light is essential for its growth.
Temperature Requirements
This plant species does well in moderate temperatures ranging from 15°C to 28 °C. However, it can tolerate a temperature range of 0°C to 35°C without significant harm when grown in an appropriate soil medium. Temperatures below 10°C can cause severe damage to the plant and halt its growth.
Soil Requirements
When it comes to the type of soil, Railliardia montana Mann var. robustior Sherff requires well-draining soils rich in organic matter. It can grow well in different soil types, including sandy and loamy soils. The ideal soil pH range for optimal growth is 5.5 to 7.5.
Most importantly, Railliardia montana Mann var. robustior Sherff requires soil with adequate moisture retention capacity. Overly wet soil can lead to root rot, which can be detrimental to the health of the plant. A soil mixture consisting of peat moss, perlite, vermiculite, and regular garden soil in equal amounts can provide an excellent growing medium for this plant.
Cultivation and Care of Railliardia montana Mann var. robustior Sherff
Railliardia montana Mann var. robustior Sherff is a beautiful and hardy perennial plant that is native to Hawaii. Here are some tips on how to properly care for this plant:
Cultivation Method
Railliardia montana Mann var. robustior Sherff is easy to grow and care for. It grows best in well-drained soil with a slightly acidic pH of 6.0 to 6.5. It prefers full sun exposure, but it also grows well in partial shade.

Propagation of Railliardia Montana Mann var. Robustior Sherff
Railliardia Montana Mann var. Robustior Sherff, commonly known as mountain daisy, is a perennial herbaceous plant belonging to the Asteraceae family. The plant is native to western North America, primarily found growing in alpine and subalpine meadows, rocky slopes, and forest margins. Propagating the plant is relatively easy and can be accomplished through a variety of methods.
Propagation through Seeds
Propagation through seeds is the most common method of propagating Railliardia Montana Mann var. Robustior Sherff. The plant produces seeds that are tiny and can be collected when matured. After harvesting the seeds, they should be properly cleaned, and the damaged seeds should be eliminated. Sow the seeds in well-draining soil that is rich in organic matter. The soil should be kept moist until the seeds germinate, which usually takes about two to four weeks. The seedlings should be transplanted into their permanent growing location when they reach four to six inches in height.
Propagation through Cuttings
Railliardia Montana Mann var. Robustior Sherff can also be propagated through stem cuttings. Take stem cuttings of about four to six inches long from a healthy plant. Remove the lower leaves from the cuttings and dip the cut ends into rooting hormone. Plant the cuttings in a well-draining soil mixture that is moist but not waterlogged. Keep the soil moist and the cuttings in a shaded location until they root, which usually takes around four to six weeks. Once the stem cuttings have established roots, they can be transplanted to their permanent growing location.
Propagation through Division
Propagation through division is another method of propagating Railliardia Montana Mann var. Robustior Sherff. This method involves dividing the crown of the plant into smaller sections. The best time to divide the plant is during the early spring when the plant starts actively growing. Carefully remove the plant from the soil and identify the growing points on the crown. Using a sharp and sterilized tool, divide the crown, making sure that each section has at least one growing point. Plant the divided sections in well-draining soil and keep the soil moist until the plant gets established in its new location.
Overall, propagating Railliardia Montana Mann var. Robustior Sherff is relatively easy and can be achieved successfully through the use of seeds, stem cuttings, or division. All the methods described above are excellent options, and the choice of method depends on the grower's preference.
