Machaeranthera havardii, commonly known as Waterfall, prefers to grow in full sun to partial shade. In its natural habitat, it is found on rocky ledges or in crevices where it receives plenty of sunlight. However, it can also grow in areas with higher shade if provided with enough light.
Temperature Requirements
This plant grows best in areas with warm temperatures, between 60-85°F (16-29°C). It is known to be quite tolerant of high temperatures, but if the temperature drops below 25°F (-4°C), it may suffer from frost damage. So, it is recommended to grow it in areas where the temperature stays above freezing point.
Soil Requirements
Machaeranthera havardii thrives in well-draining soil with neutral to slightly acidic pH (6.0-7.5). It can grow in a wide range of soils, including rocky, sandy, or loamy soils. However, it does not do well in heavy clay soils that retain moisture. It is important to avoid overwatering, as this plant is adapted to arid conditions and can tolerate some level of drought.
Cultivation Methods
Machaeranthera havardii, also known as Waterfall, is a native North American perennial that is commonly grown as an ornamental plant. This plant thrives well in full sun and can tolerate partial shade. It is adaptable to various soil conditions but prefers well-drained soil. When planting, ensure the plant is spaced at least 18 inches apart from each other. Water the plant and mulch around it to conserve soil moisture.Watering Needs
Waterfall Machaeranthera havardii enjoys evenly moist soil, so ensure that it receives regular watering during dry seasons. The plant requires about 1 inch of water per week, and the soil should be allowed to dry to a depth of about 1 inch before the next watering to prevent root rot. Water deeply instead of frequent light watering. You can tell if the plant needs watering when the soil around it starts drying out.Fertilization
To grow healthy blossoms, Machaeranthera havardii requires periodic feeding with balanced fertilizers. Fertilize the plant every two to three months during the growing season to promote blooming. Do not fertilize the plant during the winter when it is dormant. Compost and well-rotted manure would be a great organic option. Be careful with fertilizing the plant with excess nitrogen, as this may result in lush foliage at the expense of blooms.Pruning
Pruning can be done to eliminate spent blossoms, to promote new growth, and to maintain the plant size and form. Cutting off the blossom stem below the flower will encourage more flowers, and the plant will remain bushy. Prune the stems back to the basal foliage in late autumn or early spring to remove dead leaves and stems. Cut back about a third of the plant's size to maintain its shape and prevent overgrowth.Propagation of Machaeranthera havardii (Waterfall) Shinners
Machaeranthera havardii, also known as Waterfall, is a popular ornamental plant due to its attractive purple-blue flowers. It is a low maintenance perennial plant that can be propagated by various methods.
Seed Propagation
One of the easiest ways to propagate Machaeranthera havardii is by seed. Collect seeds from the mature plants that have spent flowers and seeds. The best time to sow the seeds is in the fall or early spring. Sow the seeds in soil that is moist and well-draining. Cover the seeds with a thin layer of soil. Germination should occur in two to three weeks. The seedlings should be transplanted to their permanent location when they are large enough to handle.
Division
Another method of propagating Machaeranthera havardii is by division. Division is done in the fall or early spring when the plant is dormant. Carefully dig up the plant and gently separate the root ball into smaller sections with a sharp knife or pruning shears. Each section should have a healthy part of the root system and a healthy stem. Replant the separated sections in their permanent location, water well and mulch lightly.
Cuttings
Propagation of Machaeranthera havardii can also be done by taking cuttings. Take cuttings in the summer when the plant is in its growing stage. Cuttings should be taken from healthy and mature plants, choosing a stem that is not flowering. Cut the stem below a leaf node and remove the lower leaves. Dip the cut end of the stem in rooting hormone powder and insert it in a soilless potting mix. Keep the soil moist and place the cutting in a shaded area. Once the roots have developed, plant the cutting into its permanent location.
These are the different propagation methods that can be used to propagate Machaeranthera havardii. It is an easy-to-grow plant that can be propagated readily with minimal effort and supplies. With proper care and maintenance, the propagated plants will bloom beautifully and provide year-long eye-catching flowers.
