Description
Malva 'Primley Blue' or mallow is a charming plant that brings a delightful pop of colour to your garden with its elegant, blue to purplish flowers. These blooms are delicately laced with darker veins, creating an intricate and striking contrast that catches the eye. Malva 'Primley Blue' forms a neat, ground-hugging mound, making it perfect for filling gaps in borders or softening edges. Growing to a height of around 50-70cm, it strikes a lovely balance between presence and subtlety.
What makes Malva sylvestris 'Primley Blue' particularly appealing is its versatility and low-maintenance nature. It thrives in well-drained soil and enjoys a sunny or partially shaded spot, making it a reliable addition to a variety of garden styles. Whether planted in a mixed border or as a ground cover in more naturalistic settings, Malva 'Primley Blue' adds both texture and colour. Its spreading habit ensures it fills in spaces beautifully, while the delicate flowers offer long-lasting beauty from summer into autumn. For gardeners looking for a hardy, easy-to-grow perennial that offers vibrant colour with little fuss, Malva 'Primley Blue' is the perfect choice.
Our Malva 'Primley Blue' plants are supplied as a root ball with healthy growth, ensuring a strong start. They are carefully shipped in our unique cardboard box, designed to keep them safe and in top condition. This ensures they arrive healthy and ready to thrive in their new home.
Malva is called mallow from the Old English mealwe, cherished since ancient times for its soothing leaves and cheerful, hibiscus-like blooms.

Useful information
-
Soak the Malva 'Primley Blue' roots in water for 3-6 hours prior to planting
Plant your "Mallow" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
