Description of Abutilon newberryi S. Wats.
Abutilon newberryi S. Wats., also known as Newberry's Indian mallow or the white abutilon, is a plant species that belongs to the Malvaceae family. Its name is derived from its discoverer, John Strong Newberry, who was an American geologist.
Origin
Abutilon newberryi S. Wats. is native to southern California, Arizona, and northwestern Mexico. It is commonly found in desert regions, particularly in rocky canyons or washes.
Common Names
Aside from Newberry's Indian mallow and white abutilon, the plant also has other names such as hoary abutilon, Indian mallow, and velvetleaf.
Appearance
The white abutilon is a shrub that grows up to 1.5 meters in height. It has rigid branches that are covered in a layer of fine, woolly hairs. The leaves are palmately lobed and resemble the shape of a hand, with 3-5 long and slender lobes that are toothed at the edges. The white abutilon's flowers are white to pale yellow in color and have five petals. They are relatively large, measuring up to 5 cm in diameter, and bloom between April and July. The plant produces small, woody fruits that resemble little cheese wheels.
Uses
The white abutilon has been used historically by Indigenous people for various medicinal purposes, including treating sore throats and respiratory issues. The plant's seeds have also been used to make a type of flour. Today, the white abutilon is grown as an ornamental plant in gardens and landscapes due to its attractive appearance and drought tolerance.
Light Conditions:
The Abutilon newberryi S. Wats. plant prefers partial to full sun exposure for optimal growth. It can tolerate some shade but blooms better in bright sunlight. The plant requires at least six hours of direct sunlight per day.
Temperature Conditions:
The Abutilon newberryi S. Wats. plant thrives in warm temperatures. It needs a minimum temperature of 60°F (16°C) to grow correctly. The optimum temperature range for this plant is between 70°F (21°C) to 85°F (29°C). Cool temperatures below 50°F (10°C) can cause damage to the plant's leaves.
Soil Requirements:
The Abutilon newberryi S. Wats. plant prefers well-drained soil with organic matter. The soil pH should be neutral to slightly acidic, between 6.0 to 7.5 pH. The plant can tolerate slightly alkaline soil but may experience nutrient deficiencies. To ensure good drainage, the soil should be amended with organic matter, such as compost or peat moss.
Cultivation Methods
Abutilon newberryi S. Wats., commonly known as Newberry's Indian mallow, is a plant native to the south-western United States and northern Mexico. This plant can be cultivated in well-drained soil with a pH range of 6.0-8.0. It prefers partial shade to full sun and requires moderate watering.
Watering Needs
Abutilon newberryi S. Wats. needs moderate watering. During the growing season, the top inch of soil must be allowed to dry out before the next watering. Overwatering should be avoided as it can lead to root rot and other diseases. In the winter or dormant season, the watering needs can be reduced.
Fertilization
Abutilon newberryi S. Wats. requires fertilization once a month during the growing season. A balanced fertilizer with an N-P-K ratio of 10-10-10 is suitable for this plant. Organic fertilizers like fish emulsion or compost can also be used. The fertilizers must be applied on moist soil and not on dry soil to prevent fertilizer burn.
Pruning
Pruning is not necessary for the Abutilon newberryi S. Wats., but it can be done to maintain the shape and size of the plant. Pruning must be done after the flowering season, which is usually in late fall or early winter. Any dead or diseased branches must be removed to promote healthy growth. The new growth can be lightly pruned to shape the plant.
Propagation of Abutilon newberryi S. Wats.
Abutilon newberryi S. Wats. can be propagated through both seed and vegetative propagation methods.
Seed Propagation
Collect mature seed pods from the plant and allow them to dry out completely before opening them to extract seeds. Sow the seeds in well-draining soil mixed with organic compost and cover them with a thin layer of soil. Moisten the soil and place the pot in a warm, brightly-lit location, but not in direct sunlight. Keep the soil moist and within 2-3 weeks, and the seeds will germinate.
Vegetative Propagation
Abutilon newberryi S. Wats. can be propagated through cuttings as well. Take cuttings of young and tender stems, around 10-12 cm in length, using a sterilized blade. Remove the lower leaves from the cuttings, leaving only the top few leaves. Dip the cuttings in a rooting hormone and plant them in a pot filled with a well-draining medium. Keep the pot in a warm, humid location with indirect light. In 3-4 weeks, the cuttings should develop roots and start producing new growth.
