Tightly packed blooms of snowy-white, many of which will be fully double and perfume the air with a sweet and spicy clove scent on strong, single stems. Traditionally a staple of cottage gardens, stocks have long been popular both for bedding and for providing cut flowers, but ‘Avalanche White’ would look stunning in a dark or metallic pot in a contemporary scheme, endearing itself to a whole new generation of gardeners. A hardy biennial when grown in summer for flowering early in the season of the following year, it is most commonly grown as an annual from a sowing in early spring.
How to care for Matthiola incana Avalanche:
Plant in a sunny spot with well-drained, fertile soil, adding well-rotted compost to the planting area and backfill. Space Matthiola about 30cm (12in) apart to allow good air circulation and reduce the risk of mildew.
Keep watered during dry spells and apply a monthly, liquid, general-purpose fertiliser during the growing season. Pinch out the top as they grow to encourage branching and more flower spikes, cutting back the main stem once flowers have faded to encourage side shoots to bloom too.
