Helichrysum pachyrrhizum Harv. var. huillense Hiern is a shrubby plant that grows well in warm and dry conditions. The plant is native to the southern parts of Africa and is commonly found in the Namib Desert. It is well adapted to the arid conditions of the desert and can survive even in poor soil conditions.
Light Requirements
Helichrysum pachyrrhizum Harv. var. huillense Hiern requires plenty of sunshine to grow well. The plant needs direct sunlight for at least six hours a day to thrive. Therefore, it is essential to plant the shrub in a location that receives enough sunlight. Failure to receive enough sunlight may lead to stunted growth, fewer blooms, and loss of vigor.
Soil Requirements
The plant prefers well-draining soil with low fertility. The soil should be sandy or rocky to prevent waterlogging, which may lead to root rot. The shrub can grow in poor soil conditions with a low nutrient profile, making it suitable for growth in the desert.
Temperature Requirements
Helichrysum pachyrrhizum Harv. var. huillense Hiern is tolerant to high temperatures and can grow in areas with temperatures ranging from 15-40°C. However, it is sensitive to frost, and the plant may die if exposed to freezing temperatures. Therefore, it is crucial to protect the plant during the cold season by covering it with a frost cloth or moving it indoors.
Water Requirements
The plant is drought-tolerant but requires water during the establishment period. After the shrub is well established, it can survive extended periods of drought. Overwatering may cause root rot, which may lead to the death of the plant. Therefore, it is advisable to water the plant occasionally, but deeply.
Fertilizer Requirements
The plant does not require regular applications of fertilizer. The shrub can grow in low nutrient conditions; therefore, applying fertilizer may encourage the growth of unwanted vegetation. However, if the soil is highly infertile, it is advisable to apply a slow-release fertilizer with a low nitrogen content.
