Product description

Allium 'Quattro' is a popular perennial herb, famously nicknamed a "four-in-one" plant because so many of its parts are edible. The primary part used for its culinary value is its flat, grass-like leaves, which provide a mild and savoury flavour that is often described as a perfect mix between chives and garlic. However, its edibility doesn't stop there; the attractive, globe-shaped purple flowers can also be eaten, along with the young flower stalks and the small corms that form at the base of the plant.

When it comes to planting and maintenance, this is an easy-to-grow, clump-forming perennial that is very adaptable. It is not fussy about its light conditions and will thrive in locations with either full sun or partial shade. The main requirement for it to grow well is providing it with soil that is kept moist but remains well-drained. As an added benefit to the garden, its attractive purple flowers are known to be very popular with pollinators.

Please Note: When purchasing plants please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only - The plant will be supplied in a growers pot.

Instructions

Top Tip

The showy flowers of Allium 'Quattro' are not just for decoration; sprinkle the individual florets over salads for a burst of spicy, garlic-chive flavour. This variety is sterile, meaning it won't self-seed and become a nuisance like some other ornamental alliums.

How to Water

Water Allium 'Quattro' regularly during the growing season to ensure the soil remains evenly moist but never waterlogged. Once established, it is relatively drought-tolerant, but consistent moisture helps produce the best flowers and foliage.

How to Plant

Plant Allium 'Quattro' in a sunny or partially shaded spot with well-drained soil, ensuring the bulb is covered but the foliage remains exposed.
