Verbena neomexicana (Gray) Small is a hardy plant that grows well in different types of soils. Here are the growth conditions that are suitable for this plant:
Light
Verbena neomexicana prefers full sun exposure to grow optimally. The plant requires a minimum of six hours of direct sunlight daily. If grown in a shady location, the plant tends to sprawl and become leggy.
Temperature
Verbena neomexicana thrives in warm temperature conditions. The plant is highly tolerant of heat and drought. It grows well in USDA hardiness zones 5 to 9, which have typical temperature ranges between 15 to 30 degrees Celsius.
Soil Requirements
Verbena neomexicana prefers well-draining soils with a slightly acidic to neutral pH range of 6.0 to 7.5. The soil should have good organic matter content and be rich in nutrients. It can grow in sandy and rocky soils as well as clay soils but well-draining soils are preferable to avoid root rot.
Cultivation Methods
Verbena neomexicana (Gray) Small is a perennial herbaceous plant that thrives well in well-draining soils and ample sunlight. It requires a minimum of six hours of bright sunlight daily to grow optimally. For best results, plant it in early spring in soil with a neutral pH ranging between 6.5-7.5.
The plant requires adequate spacing, as overcrowding can stunt growth. The distance between plants should be at least 10-12 inches for optimal growth.
Watering Needs
Consistent watering is necessary for Verbena neomexicana (Gray) Small. Young plants should be watered thoroughly, and the soil should be kept moist. Once it is fully established, the plant is drought-resistant and can withstand periods without water.
Avoid overwatering or allowing the soil to be continually wet, as this can lead to root rot or fungal diseases. Instead, wait until the top inch of soil is dry before watering.
Fertilization
Verbena neomexicana (Gray) Small benefits from moderate fertilization. A balanced fertilizer, like a 10-10-10, should be applied in early spring, and again in mid-summer. Slow-release fertilizers are also a good option, as they provide a steady supply of nutrients over an extended period.
Be careful not to overdose with fertilizer, as too much can harm the plant's health.
Pruning
Pruning is not always necessary, but it can help maintain the plant's health and shape. Deadheading spent blooms can encourage new growth and prolong the blooming season.
If the plant becomes too unruly, it can be cut back to 6-8 inches in early spring to promote new growth and denser foliage.
Propagation Methods
Verbena neomexicana (Gray) Small, commonly known as New Mexico verbena, can be propagated through several methods such as cuttings, seeds, and division.
Propagation through Cuttings
Propagation through cuttings is one of the simplest and easiest methods for Verbena neomexicana. Take cutting from the stem, ensure that it has a node and 2-3 leaves, and then dip it in rooting hormone. Plant the cutting in a potting mixture that is well-draining and keep it moist. Typically, roots will emerge within two to three weeks.
Propagation through Seeds
Propagation through seeds is a common method for Verbena neomexicana. Collect the seeds from the plant and sow them directly in the soil. The seeds require sunlight for germination and moist soil to develop. It typically takes around 2 to 3 weeks for the seeds to germinate.
Propagation through Division
Verbena neomexicana can also be propagated through division, which is one of the best methods to propagate mature or established plants. To propagate using this method, carefully uproot the established plant and separate its root clumps into smaller sections. Once separated, repot each section in well-draining soil and ensure they receive adequate water and sunlight.
