Species and variety notes
The straight species is tall and transparent; compact strains are easier in small beds.
A better small-space verbena than the full-height species.
Best use: cut and garden display. Tradeoff: match timing and spacing to the rest of the bed.
compact, pollinator, edge plant90-110 days24-30 inches tallUse only where height and self-sowing are acceptable.
Best use: cut and garden display. Tradeoff: needs edge placement or support so it does not shade smaller crops.
