(='Blau Saphir') Blue Flax is a favourite perennial, performing especially well in hot, sunny areas. This compact selection forms a bushy mound of small, ferny green leaves, bearing loads of small sky-blue flowers for weeks on end. Trim plants back in midsummer to encourage repeat blooming in the autumn. Excellent for edging, in the rock garden, or in mixed containers. Also suitable for naturalizing in a meadow situation. Short-lived but usually will self seed. Drought tolerant once established.
