ABOUT
The 'Toronto' is a flowering perennial known for its vibrant and showy blooms. The flowers are typically a rich purple or violet color, sometimes with white centers and a tubular shape, which give a lovely splash of color in gardens. They are clustered together at the tips of the stems, creating dense, rounded clusters that add to the plant's visual appeal. The foliage of the 'Toronto' is equally attractive, comprised of small, lance-shaped leaves that are sometimes slightly toothed. These leaves are arranged on the stem in a way that they form a lush, green background that makes the purple flowers stand out even more prominently. The overall structure of the 'Toronto' is spreading and mounding, creating a full-bodied appearance that works well as ground cover or when planted in masses. The texture added by both its leaves and flowers can provide a soft, yet lively character to garden spaces. Its long blooming period and adaptability to a wide range of growing conditions make it a popular choice for gardeners looking to add lasting color and interest to their landscapes.

Water
The Canada Vervain should be watered regularly to maintain evenly moist soil, especially during the warmer seasons. Water deeply once or twice a week, allowing the soil to slightly dry between waterings. During prolonged dry spells, you may need to increase watering frequency. Each watering session should consist of enough water to soak the soil to a depth of about 6 inches. Be cautious of over-watering; ensure the plant is in well-draining soil to prevent root rot.
Light
Canada Vervain fares best in full sunlight to light partial shade. The ideal location would receive at least 6 to 8 hours of direct sunlight each day, which promotes healthy growth and abundant flowering. Avoid deep shade as it can result in leggy plants with fewer flowers.
Temperature
Canada Vervain thrives in a temperature range between 60°F and 85°F. It can tolerate a minimum temperature of around 50°F. However, temperatures dipping below this can harm the plant. Always protect the plant from frost, which can be detrimental.
Pruning
Pruning Canada Vervain is beneficial for promoting bushier growth and more blooms. Prune lightly throughout the growing season to remove spent blooms and encourage new ones. The best time to perform a more significant pruning is in early spring to shape the plant and prepare it for new growth.
Cleaning
As needed
Soil
Canadian Vervain 'Toronto' thrives best in a well-draining soil mix with a pH ranging from 6.0 to 7.5. An ideal mix would be equal parts of loam, sand, and peat to ensure proper drainage and aeration. Regular garden soil can also be amended with organic material and perlite to improve its structure and fertility for this plant.
Repotting
Canadian Vervain 'Toronto' typically doesn't require frequent repotting and can be done every 2-3 years, or when it outgrows its current container. Ensure that the new pot has ample drainage holes and only increase the pot size gradually to prevent stress to the plant.
Humidity & Misting
Canadian Vervain 'Toronto' is tolerant of a wide range of humidity levels but performs best in moderate humidity. Avoid environments that are too dry or extremely humid to maintain the health and vigor of the plant.
Suitable locations
Indoor
Place Canadian Vervain 'Toronto' near a sunny window and ensure good air circulation.
Outdoor
Plant Canadian Vervain 'Toronto' in full sun to partial shade in well-draining soil.
Hardiness zone

Life cycle
Glandularia canadensis 'Toronto', commonly known as Toronto Verbena, begins its life cycle as a seed that germinates in spring when the soil temperature increases. Once germinated, the seedling emerges and establishes a root system while developing its first set of true leaves. As it matures during the growing season, the plant experiences vegetative growth, producing stems and leaves, and ultimately starting to branch out. The Toronto Verbena then enters the flowering stage, typically in late spring or early summer, showcasing clusters of vibrant flowers that attract pollinators. After pollination, it sets seeds which are then dispersed by wind or wildlife, and the plant may die back if it is an annual variety or become dormant in winter if it is a perennial. Finally, if the conditions allow, the seeds will overwinter and begin a new life cycle the following spring.
Propogation
Propogation time
Spring-Summer
The most popular method of propagating Glandularia canadensis 'Toronto', commonly known as Canadian Vervain or Toronto Verbena, is through stem cuttings. This technique is typically performed in late spring or early summer when the plant is actively growing. To propagate, choose a healthy, non-flowering stem and cut a 4 to 6-inch (approximately 10 to 15 cm) section just below a leaf node. Strip off the lower leaves and dip the cut end in rooting hormone to encourage root growth. Insert the cutting into a pot filled with moist potting mix or a mixture of perlite and peat. Cover the pot with a plastic bag or place it in a propagator to maintain humidity, and place it in indirect light. Roots usually develop within a few weeks after which the new vervain plant can be transplanted into the garden or into individual pots.
