Nototrichium sandwicense var. kolekolense Sherff, also known as Kolekole Pass silversword, is a rare and endangered plant species that is endemic to the island of Oahu, Hawaii. This subshrub belongs to the Asteraceae family and has adapted to grow in unique environmental conditions.
Light Requirements
Kolekole Pass silversword requires full sunlight to grow and thrive. It is a heliophyte or a plant that thrives in direct sunlight. As such, it is typically found growing on open, rocky terrain or cliff edges where there is little shading from surrounding vegetation. In cultivation, these plants need to be placed in areas with direct sunlight exposure for at least 8 hours per day.
Temperature Requirements
Nototrichium sandwicense var. kolekolense Sherff is adapted to grow in tropical climates, where temperatures range from 70 to 80°F in the day and 60 to 70°F at night. These plants are also adapted to tolerate occasional temperature drops to freezing or near-freezing temperatures. In locations with cooler temperatures, cultivation should take place in greenhouses or indoor settings where temperature can be regulated to remain within the preferred range.
Soil Requirements
Kolekole Pass silversword prefers well-drained, rocky or gravelly soils. These plants grow in high elevation areas with limited soil development, which often requires good drainage to prevent root rot. In cultivation, growers should aim to use well-drained loamy soils or a suitable mix of perlite, vermiculite, and coarse sand. ensuring that the roots don’t become waterlogged while also packing enough nutrients to support plant growth.
Cultivation methods
Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff is a rare and endemic plant species found only in Hawaii. It requires well-draining soil with consistent moisture and partial shade to thrive. It is best to start with seeds or cuttings collected from healthy plants, as they are more likely to adapt to local growing conditions. It is important to plant them in a location with partial shade and protect them from harsh winds that can damage the plant.
Watering needs
Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff requires regular watering to maintain consistent moisture but should not be left in waterlogged soil. One way to maintain proper moisture levels is to check the soil regularly and water when it feels dry to the touch. It is best to water in the morning or evening and avoid watering during the hottest parts of the day to prevent water evaporation.
Fertilization
It is recommended to use a slow-release fertilizer with a balanced ratio of nutrients to keep the Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff healthy. Fertilizers with too much nitrogen can cause excessive leaf growth at the expense of flower production. Apply fertilizer according to the instructions on the package and avoid overfertilizing, as it can lead to root burn and other problems.
Pruning
Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff does not require extensive pruning but should be pruned regularly to maintain its shape and ensure optimal health. Remove any dead or diseased leaves and stems as soon as possible to prevent the spread of disease. Remove any growth that is obstructing air circulation or interfering with other nearby plants. Pruning can be done at any time of the year but is best done in late winter or early spring before new growth begins.
Propagation of Nototrichium Sandwicense (Gray) Hbd. Var. Kolekolense Sherff
Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff or Kauai Eke is an endangered plant that is endemic to the Hawaiian island of Kauai. Propagation of this species can help in conserving and increasing its population. The plant propagates mainly via seeds and vegetative means.
Propagation via Seeds
Seeds of Nototrichium sandwicense can be collected from mature and healthy plants. The seeds should be sown immediately for better germination rates. The ideal time to sow the seeds is during the spring or early summer months, as the weather and temperature are favorable for the growth of the plant.
The seeds can be sown directly in the soil or in seed trays. Before sowing, the soil should be prepared by adding organic matter that can retain moisture. The seeds can be sprinkled on top of the soil, and a thin layer of soil should be added on top of the seeds. The soil should be moistened regularly for better germination rates.
The seedlings should be monitored and weeded regularly. The seedlings can be transplanted to their final location once they are mature enough, and the soil and weather conditions are favorable.
Propagation via Vegetative Means
Nototrichium sandwicense can also be propagated via vegetative means such as stem cuttings or division of rhizomes. Stem cuttings should be collected from healthy and mature plants during the growing season. The cuttings should be around 6-8 inches long and should be taken from the base of the plant with a sharp and sterile tool.
The cuttings should be treated with a rooting hormone and planted in well-draining soil. The soil should be kept moist, and the cutting should be placed in a shaded location until roots develop. Once the roots develop, the cutting can be transplanted to its final location.
The division of rhizomes is another vegetative means of propagation. Rhizomes are fleshy underground stems that produce roots and shoots. Healthy rhizomes can be dug out from the parent plant, and the rhizomes can be divided into sections that contain healthy roots and shoots. The sections can be planted in well-draining soil and kept moist until growth and development occur.
Disease and Pest Management for Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff
Like any other plant, Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff is susceptible to diseases and pests. Here are some of the common diseases and pests that might affect the plant and ways to manage them.
Common Diseases
Fungal diseases: The most common fungal diseases that affect Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff are root rot and leaf spot diseases. These diseases can weaken the plant and affect its growth and productivity. To manage fungal diseases, avoid overwatering the plant, improve air circulation, and trim diseased parts of the plant. Fungicides can also control the spread of fungal diseases.
Viral diseases: Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff is also susceptible to viral diseases such as mosaic virus and leaf curl virus. These diseases are spread by insects and can cause mottled leaves, stunted growth, and reduced yields. To manage viral diseases, remove infected plants, control the insect vectors, and practice good sanitation.
Common Pests
Scale insects: Scale insects are common pests that attack Nototrichium sandwicense (Gray) Hbd. var. kolekolense Sherff. They suck the sap from the plant, causing yellowing and wilting of leaves.
