Veronica ‘Royal Candles’ is a compact and vigorous speedwell known for its dense spikes of deep violet-blue flowers. This cultivar forms a neat mound of dark green foliage that sends up numerous upright flower spikes beginning in early summer. The rich blue blooms create a strong vertical accent in perennial borders and are highly attractive to bees and butterflies. ‘Royal Candles’ is valued for its improved branching habit and extended bloom period, often producing additional flowers when spent spikes are removed.
