Persian Speedwell Speedwell

Veronica persica

The Story

Plant Bio

Veronica persica, Persian speedwell, is a low sprawling annual weed from Europe and Asia, four to eight inches high, now found in lawns and cultivated ground worldwide. Small scalloped oval leaves sit along prostrate stems, and single sky-blue flowers with a white lower lip open on slender stalks from late winter onward.

It is one of the first flowers of the year in a lawn, opening in mild spells from January, and early bees use it when almost nothing else is available. Each flower lasts a single day. It is an annual, so it dies after seeding rather than persisting — improving lawn density does more to reduce it than any amount of pulling.

Uses & Benefits:

Ornamental UsesSmall clear sky-blue flowers with a white lip, opening earlier than almost anything else.
Practical UsesNone deliberate; it is a weed of lawns and cultivated ground.
Ecological BenefitsA genuine early nectar source for bees emerging in mild winter spells.

Planting

How to Grow

  1. Expect it in thin lawns and disturbed soil.
  2. Improve lawn density to reduce its foothold.
  3. Hoe or pull seedlings before they set seed.
  4. Recognise it as an annual, not a perennial weed.
  5. Leave patches in rough grass for early bees.
  6. Avoid bare soil, which it colonises fastest.

Pro Tip

It is an annual, so cutting off seeding is the whole control — a dense lawn does more than any weeding programme.
