Slender Vervain Verbena rigida
ABOUT
Verbena rigida, commonly known as slender vervain, is an attractive perennial plant with a bushy and sprawling habit. It is characterized by its rough, square-shaped stems and elongated leaves that have a rough texture and are deeply veined. These leaves are usually dark green in hue, providing a backdrop for the showy flowers. The slender vervain blooms profusely with small, tubular flowers that are tightly clustered along upright, terminal spikes. These vibrant flowers can range in color from purple to violet and are known to attract butterflies and other pollinators. The slender vervain typically blooms from midsummer through the fall, presenting a long season of color in the garden. Its striking flower spikes rise above the foliage, creating a textural and visual contrast. The overall appearance of slender vervain is that of a low-maintenance, sun-loving plant that brings a burst of vivid color and an airy, open structure to a planting space, perfect for borders, rock gardens, or as a part of a mixed herbaceous border.

- Water
The rigid verbena, or Verbena rigida, prefers a moderate watering routine, allowing the soil to dry out slightly between waterings. In general, rigid verbena should be watered once every week with about 1-2 inches of water, adjusting for rainfall and temperatures. Overwatering can lead to root rot, so ensure good drainage in the soil. During hot, dry periods, you may need to water more frequently. For container-grown plants, check the soil moisture level more often since pots can dry out faster.
- Light
Rigid verbena thrives in full sunlight conditions, requiring at least 6 to 8 hours of direct sunlight daily for best flowering and growth. It is an ideal plant for spots in the garden that receive long hours of unfiltered sun. However, in extremely hot climates, a bit of afternoon shade can prevent scorching.
- Temperature
Rigid Verbena fares well in a wide range of temperatures, but it grows best when the temperature stays between 65°F and 85°F. The plant can tolerate a minimum temperature down to 15°F, although it may die back to the ground with heavy frost. It can withstand high temperatures as long as it receives adequate moisture.
- Pruning
Pruning the rigid verbena helps to promote bushier growth and more flowers. It's best pruned in early spring or after flowering to remove dead flowers and encourage a second bloom. Typically, pruning can be done every few months during the active growing season to maintain shape and health.
- Cleaning
As needed
- Soil
Verbena bonariensis, commonly known as rigid verbena, thrives in well-draining, loamy or sandy soil with a pH of 6.0 to 7.5. For the best soil mix, combine two parts garden soil, one part compost, and one part perlite or coarse sand to ensure proper drainage.
- Repotting
Rigid verbena, often known as Verbena bonariensis, generally does not require frequent repotting as it is mostly grown as an annual. If grown as a perennial, repot every 2-3 years or when it outgrows its container.
- Humidity & Misting
Verbena bonariensis, also called rigid verbena, prefers a moderate humidity level but is quite adaptable and can tolerate the typical range found in most outdoor environments.
- Suitable locations
Indoor
Place rigid verbena in bright, indirect light with good air flow.
Outdoor
Plant rigid verbena in full sun with well-draining soil.

7-11 USDA
- Life cycle
Verbena rigida, commonly known as slender vervain, begins its life as a seed, which, when conditions are right—warm temperatures and moist soil—it germinates and emerges as a seedling. The seedling grows into a vegetative state with elongated, lance-shaped leaves and a sturdy stem, through which it undergoes vegetative growth and development. During the flowering stage, typically in late spring to summer, the plant produces dense, slender spikes of small, vivid purple flowers that are attractive to pollinators like bees and butterflies. After pollination, the flowers develop into small, brownish nutlet fruits, each containing seeds for the next generation. As the growing season ends, if the conditions are not favorable for overwintering, the plant may die off, completing its annual life cycle, or it may behave as a perennial in warmer climates by entering a period of dormancy before sprouting again in the spring. Dispersal of seeds occurs through wind, water, or animals, facilitating the spread of slender vervain to new locations where the life cycle starts anew.
- Propogation
Propogation time
Spring-summer
Propogation: The most popular method of propagating Verbena rigida, commonly known as rigid verbena, is through seed. Sowing can begin in late winter to early spring, typically around February to March for many regions. You can start the seeds indoors using seed-starting trays or small pots filled with a well-draining soil mix. Place the seeds lightly on the soil surface, pressing them gently into the soil without covering, as verbena seeds need light to germinate. Keep the soil moist but not soggy, and maintain a temperature between 70 and 75 degrees Fahrenheit (21 to 24 degrees Celsius) to encourage germination, which usually occurs within 14 to 30 days. Once seedlings are large enough to handle and after the risk of frost has passed, you can transplant them outdoors, spacing them about 10 to 12 inches (25 to 30 centimeters) apart to allow for growth and air circulation.
