Cultivation of Collinsia torreyi Gray var. latifolia Newsom
Collinsia torreyi Gray var. latifolia Newsom loves a well-draining soil and a spot that receives at least 6 hours of sunlight every day. This wildflower can tolerate a wide range of soil types but prefers slightly acidic soil with a pH range of 5.5 - 6.5.
The ideal time to sow the seeds of Collinsia torreyi Gray var. latifolia Newsom is during fall or early spring. Make sure to plant the seeds at a depth of 1/8 inch, spaced about 10 inches apart. While sowing, it is advisable to cover the seeds with a thin layer of soil in order to protect them from getting blown away by the wind.
Watering needs of Collinsia torreyi Gray var. latifolia Newsom
Collinsia torreyi Gray var. latifolia Newsom requires moderate watering to thrive. While it is essential to keep the soil moist during the germination stage, once the plant establishes, you can reduce the watering frequency. Water the plants only when the soil is dry to the touch.

Pruning Collinsia torreyi Gray var. latifolia Newsom
Collinsia torreyi Gray var. latifolia Newsom does not require pruning to maintain its shape. However, deadheading the spent flowers can encourage the plant to produce more blooms. You can cut back the plant after the flowering season to promote bushier growth.
Propagation of Collinsia torreyi Gray var. latifolia Newsom
Collinsia torreyi Gray var. latifolia Newsom is a stunning plant native to California and is commonly known as Torrey’s blue-eyed Mary. Propagation of this plant can be achieved through various methods including seed propagation and vegetative propagation.
Seed Propagation
The most common method of propagation of Collinsia torreyi Gray var. latifolia Newsom is through seed propagation. The seeds can be collected from mature plants and sown in suitable containers in a controlled environment. The seeds should be sown in well-draining soil, and the containers should be placed in a location that receives partial sunlight. The soil should be kept moist but not too wet as this can cause the seeds to rot. Germination usually occurs within two to three weeks after sowing.
Vegetative Propagation
Collinsia torreyi Gray var. latifolia Newsom can also be propagated vegetatively through stem cuttings. The stem cuttings should be taken from mature plants during the growing season and rooted in well-draining soil. The soil should be kept moist until new growth emerges. The rooted stem cuttings can then be transplanted into containers or directly into the garden.
Another method of vegetative propagation is through division. The mature plant can be carefully dug out of the ground, and the root system can be divided into sections. The sections should each have leaves and roots attached and can then be replanted into suitable locations. Watering should be done regularly until new growth emerges.
Regardless of the propagation method chosen, it is important to maintain good care of the newly propagated plants until they are fully established. This includes providing adequate water, fertilizer, and protection from pests and diseases.
Disease and Pest Management for Collinsia torreyi Gray var. latifolia Newsom
Collinsia torreyi Gray var. latifolia Newsom, commonly known as giant blue-eyed Mary, is a beautiful plant native to California. Like any other plant, it is susceptible to disease and pest attacks. However, with proper management techniques, these problems can be controlled, paving the way for the healthy growth of the plant. Below are some of the common diseases and pests that might affect Collinsia torreyi Gray var. latifolia Newsom and how to manage them.
Diseases
1. Powdery mildew: Powdery mildew is a fungal disease that affects Collinsia torreyi Gray var. latifolia Newsom, resulting in a white powdery coating on the leaves and stems. This coating weakens the plant and reduces its productivity. To manage powdery mildew, you can apply sulfur-based fungicides or neem oil to the plant's affected areas. Additionally, you can ensure that the plant receives adequate sunlight and has enough space for air circulation, preventing the spread of powdery mildew.
2. Leafspot: Leafspot is a bacterial disease that causes the leaves of Collinsia torreyi Gray var. latifolia Newsom to turn brown or yellow, resulting in defoliation if not treated. You can manage leafspot by removing and destroying any infected leaves, increasing air circulation around the plant, and using copper-based fungicides.
Pests
1. Spider mites: Spider mites are tiny pests that affect Collinsia torreyi Gray var. latifolia Newsom, causing yellow speckling on the leaves and stunted growth. To manage spider mites, you can handle the plant gently, spray it with water to dislodge the insects, use insecticidal soap, or release predator insects such as ladybugs and lacewings.
2. Aphids: Aphids suck sap from the plant's leaves, causing them to wilt and turn yellow. Additionally, aphids secrete honeydew, a sticky substance that attracts ants and other insects. You can manage aphids by introducing natural predators such as lacewings, ladybugs, or parasitic wasps, spraying the plant with water, or using insecticidal soap.
By adopting the above disease and pest management strategies, you can protect your Collinsia torreyi Gray var. latifolia Newsom plant, promote its growth, and enjoy the beauty of its blue-eyed flowers.
