This species is endemic to California and can be found in various regions such as the southern Sierra Nevada, the Tehachapi Mountains, and southwestern deserts.
Common Names
Aside from its scientific name, Hoover's lomatium is also commonly referred to as Hoover's biscuitroot, Hoover's desert parsley, and Hoover's lomatium parsley.
Uses
Indigenous people used the roots of this plant as a food source and a medicinal herb. The roots were used to soothe sore throats, coughs, and colds. The dried roots were also made into a tea to treat gastrointestinal problems. The Hoover's lomatium plant is now primarily used for its ornamental purposes in gardens and landscapes. The plant is drought-tolerant and can grow in dry soil, making it a favorite among gardeners who prefer low-maintenance plants.
General Appearance
Hoover's lomatium has an attractive appearance with its delicate, fern-like leaves and unique yellow-green flowers that bloom from February to April. The plant grows up to 30 inches in height and has a rounded shape. The foliage is grey-green and forms a basal rosette. The stems are leafless and hollow, and each stem supports up to 15 small flowers, which have five petals. The plant's roots are long and tuberous, enabling it to withstand long periods of drought.
Light Requirements
The Lomatium hooveri plant grows best in full sun to partial shade. It requires at least six hours of direct sunlight a day. Inadequate light can result in weak stems, reduced flowering, and the inability to produce seeds. Too much sunlight can cause the leaves to scorch and lead to the wilting of the plant.
Temperature Requirements
The plant is adapted to grow in warm and dry conditions. It can tolerate temperatures between 20°C to 30°C, but it is most productive when temperatures range from 25°C to 27°C. It is also able to withstand periods of drought and survive in areas with low humidity. Temperatures below 15°C, however, can damage the plant and inhibit its growth.
Soil Requirements
Lomatium hooveri prefers well-draining soil that is rich in organic matter. A soil pH of 6.0 to 7.5 is ideal for the plant’s growth. The root of the plant grows deep, and it is able to obtain nutrients from the soil. The soil should be moist, but not waterlogged, to prevent the plant from developing root rot. When planting, it is recommended to add a layer of compost or peat moss to improve the soil’s nutrient content.
Cultivation Methods
Lomatium hooveri thrives best in areas with full sun exposure, but it can grow in partial shade. It needs well-draining soil with a pH range of 6.5 to 7.5, which requires the amendment of soil ahead of planting to provide essential nutrients. It is advisable to plant in the fall or early spring, and you can propagate Lomatium hooveri using seeds, cuttings, or divisions.
Watering Needs
Lomatium hooveri is drought-tolerant, but it still requires regular watering to maintain healthy growth. Water your plant moderately, depending on the weather, and avoid overwatering to prevent fungal infections and root rot. Check the soil moisture level before watering, and water deeply enough to reach the roots, but not excessively.
Fertilization
Lomatium hooveri does not require frequent fertilization, but it still needs essential nutrients to thrive. Fertilize your plant once every year, using a balanced slow-release fertilizer in the spring. Do not apply fertilizer during the fall when the plant is preparing to go dormant for winter.
Pruning
Lomatium hooveri does not require pruning, but you may trim the dead or damaged stems to maintain its shape and remove diseased or damaged tissue. Prune your plant in the early spring before new growth appears. Cut the stem about 1/4 inch above the healthy bud or side branch at a 45-degree angle. Avoid pruning during the fall, as it may trigger new growth that can stress the plant during the winter.
Propagation of Lomatium hooveri
The plant Lomatium hooveri is a beautiful perennial herb that belongs to the Apiaceae family. Propagation is critical if you want to increase the number of these plants in your garden or natural habitat. The following are some of the propagation methods that you can use:
Seed Propagation
The most common method of propagating Lomatium hooveri is by using its seeds. The seeds of this plant are relatively easy to collect, but you need to ensure that you collect them at the right time. Wait until the seeds are fully developed and have turned a brownish-red color. Once you have collected the seeds, store them in a dry place until you're ready to plant them.
The seeds of Lomatium hooveri have a hard seed coat. You can scarify the seed coat by gently rubbing it with sandpaper or nicking it with a sharp blade. This process allows the seed to imbibe water and germinate. You can then sow the seeds in a well-drained potting mix. Keep the mix moist and warm, and you can expect the seeds to germinate within a few weeks.
Division Propagation
Division propagation involves dividing the plant's roots and transplanting them into different areas to grow. This method is suitable for mature plants that have formed dense clumps. Carefully dig up the plant, and divide the roots using a sharp knife or shovel. Ensure that each division has enough roots and foliage to establish itself in its new location. Transplant the divisions into their new location and water them regularly until they have established themselves.
Cuttings Propagation
You can also propagate Lomatium hooveri by using stem cuttings. Choose healthy stems from the parent plant, and cut them to about 4-6 inches in length. Remove the leaves from the bottom half of the cutting, leaving only a few leaves at the top. Dip the cuttings in rooting hormone and plant them in a well-drained potting mix. Place the cuttings in a warm, bright location, and keep the soil moist. Within a few weeks, the cuttings should develop roots and start to grow.
Propagation of Lomatium hooveri is not difficult, and with the right conditions, you can expect excellent results. Whether you decide to use seeds, division, or cuttings propagation, ensure that you follow the recommended procedures to encourage healthy plants' growth.
