Size: On maturity, Sea Kale typically reaches a height of about 75cm (approx. 30 inches) with a similar spread, or more . A well-grown plant makes an impressive spectacle with its hefty flower stems rising above the broad, wavy-edged leaves, the flowers are also sweetly scented.
Blooming Season: The plant flower spikes shoot up around May and June a standing high above the foliage and covered in an array of honey-scented, white blossoms, adding an ethereal charm to your garden.
In June, it was the standout plant in The Pylon Garden.

Growth & Maintenance Tips
Sea Kale, although it can be robust and hardy, still requires a touch of tender care to ensure its optimal growth. Below are some tips to help you on your Sea Kale nurturing journey:
1. Soil Conditions: This plant prefers a well-drained, sandy, or loamy soil with a slightly alkaline pH for optimal growth. Consider testing your soil’s pH balance and amend it accordingly to suit the plant’s needs.
2. Watering: Sea Kale can be somewhat drought-tolerant once established. Still, it’s important during the plant’s formative years to maintain consistent watering, being careful not to overwater and risk root rot.
3. Fertilizing: To assist with robust growth, apply a slow-release, balanced fertilizer in the early spring. This will provide your Sea Kale with all the essential nutrients it needs to bloom.
4. Pruning: It’s good practice to cut back flower stems after blooming to prevent self-seeding, unless you wish for it to proliferate. Additionally, remove any dead, diseased, or broken leaves to maintain overall plant health. See the video below👇
5. Wintering: Sea Kale is known for its hardiness, it will over winter easily in Irish gardens
