Lotus crassifolius (Benth.) Greene var. otayensis Moran ex Isely is a plant species that belongs to the pea family, Fabaceae. It is more commonly known as Otay lotus or Otay deervetch. This plant is native to southern California and northern Baja California, where it can be found growing in a variety of habitats ranging from rocky hillsides to sandy beaches.
General Appearance
The Otay lotus is a low-growing perennial herb that typically reaches a height of 4-12 inches and a spread of 2-4 feet. It has a prostrate growth habit, meaning that it spreads out along the ground, forming a dense mat of foliage and stems. The leaves are thick and succulent, with a bluish-green color and rounded shape. The plant produces small, yellow pea-like flowers that bloom from late winter to early spring.
Uses
Lotus crassifolius (Benth.) Greene var. otayensis has long been used for its medicinal properties by Native American tribes in the region. The leaves and stems of the plant were used to make a tea that was believed to have a variety of healing effects, including reducing fever and relieving gastrointestinal issues. Some tribes also used the plant as a food source.
In addition to its medicinal and culinary uses, the Otay lotus is also used in landscaping and erosion control. Its prostrate growth habit and ability to form dense mats of foliage make it an excellent ground cover, particularly in sandy or rocky soils. It is also drought-tolerant and requires little maintenance, making it a popular choice for xeriscaping and other low-water gardening techniques.
Growth Conditions for Lotus crassifolius var. otayensis
Light: This plant thrives in direct and full sunlight, making it an excellent choice for open areas with abundant sunlight.

Cultivation of Lotus crassifolius var. otayensis
Lotus crassifolius var. otayensis is a hardy aquatic perennial plant that requires a lot of sunlight to thrive. The plant can be grown in garden ponds, ornamental pools, and other water features.
Watering needs
This plant is adapted to grow in water, so it requires a lot of moisture to thrive. Water levels should be maintained at a depth of around 2 to 3 feet. The plant should not be allowed to dry out, as this can cause stress and damage to the roots.
Fertilization
It is essential to feed lotus crassifolius var. otayensis regularly for healthy growth. Fertilization should be carried out during the growing season, which typically runs from spring to autumn. A balanced fertilizer with a high phosphorus and potassium content is recommended.
Pruning
Pruning is essential for maintaining the health and appearance of lotus crassifolius var. otayensis. Dead leaves and flowers should be removed promptly to prevent them from rotting in the water and attracting pests and diseases. Additionally, pruning can also be used to manage the size and spread of the plant.
Propagation of Lotus crassifolius (Benth.) Greene var. otayensis Moran ex Isely
Lotus crassifolius (Benth.) Greene var. otayensis Moran ex Isely, also known as Otay Mountain lotus, is a perennial herbaceous plant that belongs to the family Fabaceae. This plant is native to Southern California, particularly in San Diego and Baja California.
Propagation by Seed
The easiest and most common method of propagating Lotus crassifolius var. otayensis is through seeds. Seeds can be directly sowed on prepared soil in the fall or winter, and will usually germinate in the following spring. To improve the germination rate, scarify the seeds by rubbing them gently with sandpaper or nicking the seed coat with a sharp blade before sowing. Alternatively, you can also soak the seeds in warm water overnight to soften the coat. After sowing, keep the soil consistently moist and provide bright, indirect light.
Propagation by Division
Lotus crassifolius var. otayensis can also be propagated through division. This method involves splitting the plant into smaller sections, each with its own roots and shoot system. This method is best done in spring or fall, when the plant is not actively growing. To divide the plant, carefully remove it from the soil and shake off any excess soil. Use a sharp, sterile knife to cut the plant into two or more sections. Each section must have at least one shoot and a portion of the root system. After dividing, plant each section in a prepared pot or bed, and keep the soil consistently moist. Avoid direct sunlight until the new growth is established.
Propagation by Cuttings
Another method of propagating Lotus crassifolius var. otayensis is through cuttings. This method involves taking a stem cutting from the plant and rooting it in a pot or tray. The best time to take cuttings is in spring or summer when the plant is actively growing. Select healthy stems that are at least 4 inches long and cut them just below a node. Strip the bottom leaves from the cutting and dip the cut end in rooting hormone powder. Place the cutting in a pot or tray filled with a well-draining potting mix, and cover it with a plastic bag to create humidity. Keep the soil moist and in bright, indirect light. The cutting will take root in 2-4 weeks and can be transplanted into a larger pot or bed when it has established new growth.
Disease Management
Lotus crassifolius (Benth.) Greene var. otayensis Moran ex Isely is generally a hardy plant, but there are a few diseases that can affect it.
One common disease that affects Lotus crassifolius is root rot, caused by soil-borne fungi. To prevent root rot, it is important to plant the seedlings in well-draining soil and avoid overwatering. In case of infection, remove the infected plants and treat the remaining ones with a fungicide.
Another disease that affects this plant is leaf spot, caused by the fungus Cercospora. Leaf spots appear as small, brown spots on the leaves, and can result in defoliation if not treated. Remove the infected leaves and apply a fungicide. It is also important to practice good sanitation by removing dead leaves and debris from the plant and surrounding area.
Pest Management
Lotus crassifolius (Benth.) Greene var. otayensis Moran ex Isely is also susceptible to some pests, which may cause significant damage if not controlled.
The most common pest that affects this plant is the spider mite. Spider mites are tiny, sap-sucking insects that feed on the undersides of leaves, causing yellowing and stippling. To control spider mites, spray the plant with insecticidal soap or neem oil. It is also important to keep the plant well-hydrated and avoid letting it dry out, as dry conditions can encourage spider mite infestations.
Another pest that can affect this plant is the caterpillar of the silver-spotted skipper butterfly. These caterpillars feed on the leaves of the plant and can defoliate it if not controlled. To manage caterpillar infestations, handpick the caterpillars off the plant and dispose of them. You can also apply an insecticide, but make sure to choose a product that is safe for butterflies, as they are important pollinators.
Finally, aphids can also infest Lotus crassifolius. These tiny insects feed on the sap of the plant and can cause stunted growth and yellowing leaves. To control aphids, spray the plant with a strong stream of water to dislodge them, or apply insecticidal soap or neem oil.
