Blooming from May to September, it reaches a height and spread of 45cm, making it ideal for borders, containers, and pollinator-friendly gardens. Hardy and low-maintenance, this variety thrives in full sun or light shade with free-draining soil and is a favourite of bees and butterflies.

PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant Nepeta racemosa ‘Snowflake’ is in spring. Warmer soil temperatures allow the roots to settle in quickly, encouraging healthy growth and flower production throughout the season.
• Autumn: Alternatively, planting in early autumn gives Nepeta racemosa ‘Snowflake’ enough time to establish its roots before winter dormancy, resulting in a strong start come spring.

Site Selection

• Sunlight: Nepeta racemosa ‘Snowflake’ thrives in full sun but also performs well in light shade. Choose a site that receives at least 5–6 hours of sunlight a day for the best flowering results.
• Soil: This perennial prefers free-draining soil. Avoid locations where water tends to pool. Enhance drainage by mixing in coarse sand or grit, and enrich the soil with compost to improve texture and fertility.

Planting Instructions

1. Prepare the Hole: Dig a hole twice as wide and the same depth as the root ball of your Nepeta racemosa ‘Snowflake’.
2. Soil Enrichment: Combine compost with the removed soil to improve nutrients and drainage.
3. Planting: Place the plant so the top of the root ball is level with the soil surface. Backfill gently, firming the soil around the base.
4. Watering In: Water thoroughly after planting to help the roots settle. Ensure excess water drains freely to prevent root rot.

Watering Requirements

• During Growth: Nepeta racemosa ‘Snowflake’ is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry between watering.
• Dormant Period: Reduce watering significantly during winter. Only water if prolonged dry periods occur.

Feeding

• Apply a balanced, slow-release fertiliser in early spring to support new growth and flowering.
• A second light feed in mid-summer can prolong the flowering season of Nepeta racemosa ‘Snowflake’.

Pruning

• Deadheading: Regularly remove spent flower spikes to promote continuous blooming.
• Cutting Back: After the final flush of flowers in autumn, cut back Nepeta racemosa ‘Snowflake’ to just above ground level. This tidies the plant and encourages vigorous growth the following spring.

Mulching

• Apply a layer of mulch in spring to retain moisture, suppress weeds, and regulate soil temperature. Use organic mulch such as bark chips or compost.
• Refresh mulch in autumn to offer added root protection and boost soil health.

Supporting the Plant

• Nepeta racemosa ‘Snowflake’ typically has a compact growth habit and doesn’t usually require staking. However, in windy or exposed gardens, a low support ring may help maintain shape during peak bloom.

Final Tips
