It is commonly known as Goodding's Purple Aster and is an evergreen perennial that can usually grow up to 2 feet tall. The herbaceous plant is native to the Sonoran Desert regions of Arizona, California, and Northern Mexico.
Propagation Methods
Machaeranthera pinnatifida ssp. gooddingii can be propagated from seeds or cuttings. Here are some details on the propagation methods:
Propagation from Seeds
One of the easiest methods to propagate Machaeranthera pinnatifida ssp. gooddingii is by using seeds. The seeds are available in the market or can be collected from the plant. The best time to sow the seeds is in the spring as the temperature range is ideal.
Once the seeds are collected, place them in a container with a well-draining soil mix. The optimal temperature range for the seeds to germinate is between 70°F to 75°F. Ensure to keep the soil moist, but not soggy. The seeds can take up to 2 weeks to 2 months to germinate, and once the seedlings grow, transplant them to individual pots with adequate spacing.
Propagation from Cuttings
Propagation of Machaeranthera pinnatifida ssp. gooddingii can also be done through cuttings. It's best done in the spring or the fall when the plant is actively growing. Cuttings can be taken from the stem tips, preferably with a pair of sterilized snips.
Once cut, remove the lower leaves and dip the end of the cutting in rooting hormone. Root the cutting in a well-draining mix like perlite or vermiculite for at least 2 to 3 weeks. Ensure that the cuttings get enough light and stay moist throughout the process. Once rooting occurs, you can transplant the cuttings into individual pots or out in the garden.
In conclusion, Machaeranthera pinnatifida ssp. gooddingii is a gorgeous plant that can be easily propagated by seeds or cuttings. Both methods are easy to follow, and you can quickly expand your garden with more of these beautiful flowers.
Disease and Pest Management for Machaeranthera pinnatifida (Hook.) Shinners ssp. gooddingii (A. Nels.) B.L. Turner & Hartman
Machaeranthera pinnatifida (Hook.) Shinners ssp. gooddingii is a hardy native plant, but like any other plant, it is susceptible to certain diseases and pests. Here are some of the common ones and how to manage them.
Diseases
Root Rots
Root rots are fungal infections that affect the root system of the plant. Symptoms include drooping foliage, discoloration of leaves, and stunted growth. To manage root rots, it is essential to prevent waterlogging. Ensure adequate drainage and do not over-water the plant. In severe cases, it may be necessary to remove affected plants.
Leaf Spot
Leaf spot is a fungal disease that causes circular spots on the leaves, which gradually turn brown and fall off. The fungus thrives in humid conditions and can spread quickly. To manage leaf spot, remove and dispose of affected leaves, and avoid overhead watering. Fungicides may be necessary in severe cases.
Bacterial Wilt
Bacterial wilt is a bacterial disease that affects the vascular system of the plant, causing it to wilt and die. It is spread by insects and contaminated soil. To manage bacterial wilt, remove and dispose of affected plants, practice crop rotation, and avoid using contaminated soil. Insecticides may be necessary to control insect vectors.
Pests
Aphids
Aphids are tiny, soft-bodied insects that suck sap from the plant, causing distorted leaves and stunted growth. To manage aphids, spray the plant with a strong stream of water or use insecticidal soap.
Spider Mites
Spider mites are tiny arachnids that also suck sap from the plant, causing yellowing of leaves and webbing on the plant. To manage spider mites, use a strong stream of water to wash the plant, or use insecticidal soap or a pesticide specifically designed for spider mites.
Beetles
Beetles, such as the flea beetle, can cause extensive damage to the plant by feeding on the foliage and leaving behind small holes. To manage beetles, use insecticides or sticky traps.
By following these disease and pest management practices, you can keep your Machaeranthera pinnatifida (Hook.) Shinners ssp. gooddingii plants healthy and thriving.
