Light Requirements
Lotus heermannii var. eriophorus thrives in full sun or partial shade. The plant requires an adequate amount of direct sunlight to produce healthy foliage and blooms. It should be planted in an area that receives six to eight hours of direct sunlight a day.
Temperature Requirements
This plant variety can withstand a wide range of temperature and climate variations. It grows optimally in USDA hardiness zones 8 to 11. Lotus heermannii var. eriophorus prefers moderate temperatures with not too hot during the day and not too cold at night. During periods of harsh cold, it goes dormant and dies back to the ground.
Soil Requirements
The plant typically grows well in a variety of soils, including sandy, loamy, or clayey soils. It prefers well-drained, moist soils and can tolerate drought for brief periods. Soil pH should be neutral and range between 6.5 to 7.5. Additionally, it should be fertilized annually to maintain robust health and promote good flowering.
Cultivation Method
Lotus heermannii var. eriophorus is a perennial herb that can grow up to a height of 3 feet and spread over an area of 6 feet. It requires full sun exposure and moderate watering. The plant can adapt to various types of soils and can even grow in saline soils. However, it is recommended to grow it in well-drained soil with a pH level of 6 to 8. The plant can be propagated by seeds or stem cuttings.
Watering Needs
Lotus heermannii var. eriophorus requires moderate watering to thrive. The plant prefers moist soil but can tolerate minimal drought once established. The frequency of watering should be reduced during the winter season. Overwatering can lead to root rot and wilting of the plant. Watering the plant in the early morning or late evening is recommended to reduce water loss due to evaporation.
Fertilization
Lotus heermannii var. eriophorus is a light feeder plant, and therefore, it does not require frequent fertilization. A well-drained nutrient-rich soil is enough to provide the plant with the required nutrients. However, if you want to promote plant growth and flowering, you can add a balanced all-purpose fertilizer once every two months during the growing season. Avoid over-fertilization as it can lead to weak stems and leaves.
Pruning
Lotus heermannii var. eriophorus does not require frequent pruning but may need occasional grooming. Deadheading spent flowers and removing dead, yellow or discolored leaves encourages healthy plant growth. You can prune the plant at the beginning of the growing season to encourage branching and new growth. Trim back any old or weak stems to promote better air circulation and prevent overcrowding.
Propagation methods for Lotus heermannii (Dur. & Hilg.) Greene var. eriophorus (Greene) Ottley
Lotus heermannii (Dur. & Hilg.) Greene var. eriophorus (Greene) Ottley, commonly known as Heermann's lotus, is a California native perennial plant. This plant species is a drought tolerant and low maintenance plant, which makes it an excellent candidate for propagation. Here are some propagation methods:
Seed Propagation
Seed propagation is the most common method to propagate Lotus heermannii var. eriophorus. The best time to collect seeds is after the pod has dried on the plant. Once collected, remove the seeds from the pod and store them in a cool and dry place until you are ready to plant. In the fall season, sow the seeds in the soil and cover them lightly with soil. Keep the soil moist, and in a few weeks, the seeds will germinate and grow.
Division Propagation
Lotus heermannii var. eriophorus can also be propagated by dividing the existing plant. The best time to divide the plant is in the early spring before new growth appears. To divide the plant, dig it out of the soil and remove the excess soil from the roots. Then, use gardening shears to cut the plant into several sections. Make sure each section has enough roots to support growth. After that, replant each section as soon as possible.
Cuttings Propagation
Cuttings propagation is also a practical method to propagate Lotus heermannii var. eriophorus. Take a cutting from the parent plant in the spring season, making sure it has at least two leaf nodes. Remove the bottom leaf node and then dip the cutting in rooting hormone to stimulate root growth. Put the cutting in a container filled with moistened potting soil mix and keep it in a warm and humid place. After a few weeks, the cutting should develop roots, and you can transplant it into the soil.
