- Species and varieties: Convolvulus tricolor, commonly known as Dwarf Morning Glory or Bindweed, is a species of flowering plant in the bindweed family, Convolvulaceae. It is native to the Mediterranean region and is known for its vibrant, tricolor flowers that typically feature blue, white, and yellow hues.
- Hybrid or heirloom: Convolvulus tricolor is generally available as an heirloom variety, meaning it is open-pollinated and has been passed down through generations without genetic modification. This makes it a popular choice for gardeners looking to preserve traditional plant varieties.
- Pruning and training: Convolvulus tricolor requires minimal pruning. Deadheading spent flowers can encourage more blooms and extend the flowering period. It can be grown as a ground cover or trained to climb on supports, although it does not have tendrils and may need some assistance to climb.
- Fertilization needs: This plant is not particularly demanding in terms of fertilization. A balanced, all-purpose fertilizer applied once a month during the growing season can promote healthy growth and abundant flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
- Hardiness zones: Convolvulus tricolor is suitable for USDA hardiness zones 7-10. It thrives in warm climates and can tolerate mild frost, but it is not suitable for extremely cold regions.
- Climate requirements: This plant prefers full sun and well-drained soil. It is drought-tolerant once established but performs best with regular watering during dry periods. It is ideal for Mediterranean climates but can also be grown in other regions with similar conditions.
