Brunnera 'Sea Heart'
- Few plants have foliage quite like Brunnera 'Sea Heart', its green-etched, silver leaves illuminating flower beds wherever they're found.
- A great option for groundcover, this brunnera also sports wonderful blue blooms throughout the heart of spring. The delicate single flowers work beautifully against the backdrop of silver foliage.
- Brunneras look brilliant as part of a woodland planting scheme, but they actually cope well with all light levels, from deep shade right the way through to sunny spots.
- A relatively compact, clump-forming perennial, 'Sea Heart' also grows nicely in containers on a patio terrace or balcony.
- 'Sea Heart' is certified as one of the Royal Horticultural Society's Plants for Pollinators, indicating its benefits to pollinating insects like bees and butterflies.
