Dutchman's Gold
Dutchman's Gold, botanical name Lotus berthelotii, is an evergreen sub-shrub native to the Canary Islands, growing to a height of 30-90 cm depending on the variety. It has lax, willowy, finely-divided greyish-green foliage from which small yellow and white daisy-like, single or double flowers appear in the summer. The blooms are favoured by pollinators, and attract bees and butterflies. The flowers are followed by hard woody capsules containing a number of black seeds.
During the summer growing season, when temperatures are high and the plant is flowering, Dutchman's Gold needs regular watering. Water thoroughly until water comes out of the pot’s drainage holes. During the winter months, water sparingly, but don’t let the soil dry out completely or the plant may suffer. Also, avoid overwatering as this may lead to root rot.
Dutchman's gold prefer sunny conditions and can also withstand partial shade. Too much shade, however, will encourage the plant to become leggy and less able to form a tight mound. Protect plants from extreme midday heat in the summer to avoid sunburn.
Dutchman’s Gold plants enjoy relatively warm temperatures and do not tolerate extreme cold. Ideal temperatures should range between 65°F (18°C) to 77°F (25°C). Temperatures below 50°F (10°C) can affect the growth of the plant.
Dutchman’s Gold enjoys a humid environment with sufficient air circulation. Generally, high humidity is not necessary as long as the plant is not exposed to periods of draughts. However, increased humidity can be beneficial for the foliage and when the plant is flowering.
Dutchman’s Gold prefers well-draining soil with a neutral pH. It also prefers a peat-based potting mix, with a small proportion of perlite for aeration. Since the plant will not tolerate wet soil, use soil with good drainage, such as cactus/succulent potting mix.
During the growing season, apply a balanced liquid fertilizer every two weeks. Avoid application of fertilizer when the flowering period begins. During cold winter months, reduce the amount of fertilizer applied to fertilize only once. When fertilizing, use a liquid fertilizer that is specially formulated for cactus and succulents. Also, be sure to dilute it to half of the recommended concentration to avoid root burn.
Dutchman’s Gold are quite resistant to pests, however, it can suffer from common ailments, such as root rot, root-knot nematodes, spider mites, aphids and caterpillars. If you see any of these pests on your Dutchman’s Gold, it is important to act quickly to minimize damage, otherwise, the plant may die. To get rid of root rot, overly moist soil should be replaced with well-draining soil. To get rid of root-knot nematodes, the soil should be treated with a nematode-killing soil drench. To prevent or get rid of spider mites, pest-killing soaps and oils can be used. To prevent or get rid of aphids, insecticidal soaps can be used, or ladybugs can be released in the area. To get rid of caterpillars, sprays containing B.t can be used.
Repot Dutchman’s Gold every 2-3 years for optimal growth. When repotting, use a pot that is one size bigger than the existing one. Make sure that the pot has drainage holes as good drainage is essential for the health of the plant. Before repotting, make sure that the current soil is moist. Use a potting mix that is specially formulated for cactus plants or succulents to ensure the best drainage. Also, add a layer of gravel at the bottom of the pot before adding the soil.
Prune or trim Dutchman’s Gold to keep its compact shape every once in a while. Cut or pinch off any long and unruly stems or shoots that threaten to unbalance the symmetrical shape of the plant. Pruning should be done after flowering in the spring.
Mulching is not essential for Dutchman’s Gold but it can help protect the plant from extreme temperatures and conserve the moisture in the soil. Use a light layer of mulch, such as shredded bark or wood chips, on the surface of the soil.
Dutchman’s Gold can be propagated from seeds or by cuttings. Sow the seeds inside and slightly cover them with soil. Keep the soil moist and keep the temperature between 65-77°F (18-25°C). It may take about a month for germination. For cuttings, take semi-hardwood or hardwood cuttings from the spring growing season and insert them into the soil. Keep the soil slightly moist and provide bright but indirect sunlight. After about a month, the cutting should begin to root.
Young plants may need support to help them hold up their weight as they grow and mature. If necessary, use a stake or trellis to support the plant and keep it upright.
Dutchman’s Gold do not need a rest period, but they may benefit from one during periods of extreme cold or drought. During this period, reduce the amount of water and fertilizer given to the plant and provide protection from extreme temperatures.
Dutchman’s Gold is not known to be toxic to pets. However, it is still best to keep pets away from the plant, especially if they are nibblers.
