Last Review
Features
Large clusters of flowers (white, pink or blue), in summer; flower form depends on cultivar, some have "lacecap" flowers (small fertile flowers surrounded by showy fertile flowers), others have a globose form (all larger, sterile flowers); summer foliage is a lustrous, bright green.
Culture
Full sun to partial shade; moist, well-drained soil is preferred.
Notes
<p>Blue flower color will only be produced in acid soils, usually in the 5.0-5.5 range.</P>
<p>This shrubs grows in zone 5, but does not usually flower there. This species flowers on last year's wood and in zone 5 the plant dies down to the ground so there is no old wood. New cultivars are being selected for flowering on new growth (see cultivars).</P>
