We lust after Victorian golden-leaved heliotropes such as the French variety Albert Delaux described in 1892–an ephemeral beauty lost to history. However, newer heliotropes, such as 'Fragrant Delight', still have that irrepressible fragrance so valued by past gardeners. Summer to frost, vanilla-scented amethyst flowers bloom in sprays over dark green quilted leaves. Water and fertilize regularly and evenly for the best growth and flowering.
