Round 'n Purple ornamental allium stands out for its impressive height and striking visual impact in any border. This variety is known for its large, dense, globe-shaped flower heads packed with deep purple, pigment-rich florets. Carried on tall, upright stems, these blooms create a bold feature that draws the eye, making it an ideal choice for those seeking structure and colour without complicated care requirements. Even beginner gardeners will find it easy to grow, as it thrives without the need for specialist knowledge or attention.
For best results, plant the Round 'n Purple allium bulbs in autumn - September to October is the ideal window. This timing allows the bulbs to establish strong roots before winter sets in.
Each bulb should be planted at a depth of around 15 cm. This ensures optimum protection from frost and gives the bulb the conditions it needs to develop fully.
Leave 20-25 cm between bulbs when planting. This spacing gives each plant enough room to grow and ensures that the tall flower heads can form impressive, well-shaped clusters.
Round 'n Purple reaches an impressive height of 90-120 cm, making it one of the taller garden bulbs available. Its vertical presence means it works well both as a backdrop to lower perennials and as a companion to lilies or foxtail lilies.
This allium comes into flower from May to June. During this period, its tall stems are topped with large, spherical heads made up of hundreds of tiny purple stars, delivering a dramatic display at the start of summer.
Round 'n Purple is fully hardy and does not require lifting for winter. The bulbs withstand low temperatures with ease, which keeps maintenance simple and reliable year after year.
Ideal for perennial borders, naturalistic gardens, or as a striking single feature, Round 'n Purple also makes an excellent cut flower. The blooms keep well in vases and are suitable for drying. Their strong scent helps deter rodents, adding a practical benefit. This variety pairs attractively with lilies, foxtail lilies, and perennials with contrasting foliage or flower colours. As one of the top quality bulbs and plants for visual impact, it is a popular choice for those looking to enhance their planting schemes with long-lasting structure.
