Description

Hollyhock ‘Polarstar’ offers towering presence and crisp, luminous beauty. This striking cottage garden classic sends up tall, sturdy spires lined with large, single white flowers, each centred with a soft yellow eye that seems to glow in summer light. Its upright, architectural habit makes it perfect for adding height to borders, softening walls, or creating a graceful screen, while its open blooms are a magnet for bees and butterflies. Part of the Spotlight series, it blends traditional charm with improved vigour, delivering cottage garden elegance that lifts any planting scheme. Ultimate height: 1.5m (4.9ft) to 2.5m (8.2ft). Ultimate spread: 1m (3.2ft).

How to Grow
Plant out Hollyhocks in sunny borders in fertile, well drained soil. Choose a position that is sheltered from strong winds. Space hollyhock plants at least 60cm (24") apart to improve air circulation and help prevent hollyhock rust.

For more information and guidance check out our Gardening Guides.

More Info
Feed and water regularly until hollyhocks are fully established. Support their tall stems with bamboo canes as the flower spikes develop. In autumn, cut back the old foliage and faded hollyhock flower stems, and apply a mulch of well rotted manure or garden compost to the base of the plant.
