Aloha Centaury - Organic
The Aloha cornflower is a floriferous annual variety that instantly brings a sense of freedom and movement to the garden. Its delicate flowers, borne on slender, supple stems, open in a palette of bright and harmonious colors, evoking the flowering meadows of yesteryear while blending perfectly into contemporary gardens.
Derived from the annual cornflower ( Centaurea cyanus ), the Aloha cornflower is distinguished by its abundant and prolonged flowering. It naturally attracts attention without ever overpowering other plants, easily finding its place in borders, light flowerbeds, or at the heart of a flowering vegetable garden. Its rapid growth and airy habit make it a valuable ally for filling spaces and adding dynamism to landscaping.
In the garden, it is undemanding and tolerant, preferring well-drained soil and a sunny location. Once established, it requires little care and offers continuous flowering throughout the summer, especially if you take the time to regularly remove faded blooms.
