Origin and Common Names
Eragrostis x pseud-obtusa De Winter, also known as Sporobolus × wrightii Munro ex Scribn. & Merr. var. wrightii, is a hybrid plant species that originated from crossing Eragrostis obtusa and Eragrostis spicata. This plant is commonly called savannah lovegrass or weeping lovegrass.
General Appearance
Savannah lovegrass is a warm-season grass that grows best in sunny open areas with well-draining soils. The plant can grow up to 3 feet tall and has fine-textured, light green leaves that are about 1/8 inch wide and 4-12 inches long. It has a moderate drought tolerance and can spread through rhizomes and seed heads.
The seed heads are made up of delicate, branching inflorescences that resemble a weeping willow tree, giving the plant its common name. These inflorescences are composed of long, silky white hairs that can be used decoratively in floral arrangements or as an alternative to traditional hay for feeding livestock.
Uses
Savannah lovegrass is primarily used for ornamental purposes, including landscaping and erosion control. It is a popular choice for revegetating disturbed or damaged areas, as it spreads quickly and helps stabilize loose soils. Additionally, it provides a natural habitat for small animals, such as birds and insects.
In some regions, savannah lovegrass is also used for forage for grazing livestock. The plant has a high nutritive value, with a crude protein content ranging from 8-13% and a digestibility rate of 50-60%. However, its use as forage is limited due to its low tolerance for heavy grazing and its tendency to become invasive in some areas.
hereLight Requirements
Eragrostis x pseud-obtusa De Winter is a plant that requires full sun exposure for optimal growth. Intense sunlight encourages healthy growth, resulting in better plant development, strong stems, and an increase in foliage.
Temperature Requirements
The Eragrostis x pseud-obtusa De Winter can easily adapt to a broad range of temperatures. However, it thrives best in temperatures ranging from 70 to 80 degrees Fahrenheit. Temperatures exceeding 85 degrees Fahrenheit may lead to stunted growth and wilting of the plant.
Soil Requirements

Cultivation Methods
Eragrostis x pseud-obtusa De Winter typically thrives in well-draining soils, with a pH level between 6 and 7.5. These grasses perform best in full sun and can tolerate high temperatures.
It's essential to plant Eragrostis x pseud-obtusa De Winter in a location with good air circulation, and the soil needs to be moist, but not excessively wet. This plant should be planted at a depth no greater than the height of the root mass.
Watering Needs
Water the grasses regularly, providing 1 to 2 inches of water per week. In times of drought, the grass may need more frequent watering. However, be sure to monitor the soil, as too much water can harm the roots, and lead to diseases like rot.
Fertilization

Pruning
Eragrostis x pseud-obtusa De Winter requires minimal pruning, mainly when it comes to removing any dead or damaged leaves or stems. Wait until spring to begin trimming the plant. Be sure to avoid pruning too low, as this can damage the crown of the plant.
Propagation of Eragrostis x pseud-obtusa De Winter
Eragrostis x pseud-obtusa De Winter is a fascinating ornamental plant, which is propagated by seeds and division of the clumps.
Propagation by seeds
The propagation of Eragrostis x pseud-obtusa De Winter by seeds is easy and effective. You can collect the seeds when the plant reaches maturity and dry them in the sun for a few days. After that, you can plant the seeds in a well-draining soil mix, water them, and put them in a warm place with enough sunlight. The seeds will germinate in a few weeks, and you can transplant them when they reach a suitable size.
Propagation by clump division
Another effective way of propagating Eragrostis x pseud-obtusa De Winter is through clump division. You can divide the plant in spring or early autumn by separating the root ball into smaller sections. Each section must have a healthy root system and a few plant shoots. After separating the sections, you can plant them in individual pots or directly in the ground. Water the plant regularly, and new growth will emerge within a few weeks.
Propagation of Eragrostis x pseud-obtusa De Winter is an easy and rewarding process, and you can enjoy this ornamental plant in your garden or home in no time.
Disease Management
Eragrostis x pseud-obtusa De Winter is relatively disease-free. However, it is still susceptible to some fungal and bacterial diseases. The most common diseases that affect this plant are root rot, leaf spot, stem rot, and rust.
The preventive measures for these diseases are to ensure proper soil drainage, avoid overhead watering, and maintain good airflow around the plant. Additionally, you can use fungicides to control the spread of fungal and bacterial diseases. Always read and follow the label instructions for effective application.
