Dwarf Morning Glory

Convolvulus tricolor

The Story

Plant Bio

Convolvulus tricolor, dwarf morning glory, is a bushy annual from the Mediterranean and North Africa, twelve to eighteen inches high and about as wide. Thick hairy angular stems form a dense cascading mound, and funnel-shaped flowers one to three inches across open in deep blue with a white and gold throat, giving the three colours of its name.

It is a morning glory that does not climb, which makes it a safe choice where its twining relatives would be a menace — it mounds and cascades instead, suiting baskets and pot edges. The flowers open with the sun and close by mid-afternoon or in dull weather, so plan for a morning display rather than an all-day one.

Uses & Benefits:

Ornamental UsesIntense tricolour funnels of blue, white and gold on a neat cascading mound.
Practical UsesThrives on poor dry soil, needs no support, and never becomes the nuisance a climbing morning glory can.
Ecological BenefitsBees, butterflies, moths and hummingbirds all visit the open flowers.

Planting

How to Grow

  1. Sow direct after the last frost in full sun.
  2. Give it any freely drained soil; poor is fine.
  3. Do not feed, which favours leaf over flower.
  4. Water sparingly once established.
  5. Expect flowers to close by mid-afternoon.
  6. Deadhead lightly to prolong the season.

Pro Tip

Unlike its climbing cousins this one mounds and never twines, so it can go where a true morning glory would be a mistake.
