🌸 Ageratum mexicanum Floss Flower ‘Tall Red Flint’ – Tall Ageratum with Rich Red Fluffy Blooms
‘Tall Red Flint’ is a striking tall-growing floss flower (ageratum) variety producing dense clusters of soft, fluffy flowers in deep red to crimson tones.

Unlike compact bedding ageratums, this variety offers extra height, making it ideal for borders, cutting gardens, mixed beds, and pollinator-friendly plantings.
Key Features
● Fluffy, pom-pom–like flowers in rich red shades
● Taller habit than standard ageratum varieties
● Long flowering season from summer to autumn
● Excellent for borders and cut flowers
● Easy to grow and very reliable
