Welsh Onion(Allium fistulosum)Herb in 9cm Pot

Welsh onion is a bulbous bunch forming herbaceous perennial with a strong onion or garlic scent, it produces cylindrical bulbs, pencil thick stems and hollow leaves up to 30cm. Producing a pretty umbel of bell shaped yellow-white flowers on a leafless stem, this mid-summer show can be quite lovely. They do have a culinary use but can also be grown to feature in flower borders and beds especially popular in Cottage style planting and Informal Gardens. They enjoy full-sun to partial shade but also like to be kept moist. Dead-Head After flowering to allow all the nutrients back onto the bulb and avoid self seeding unless this is desired.

Herb Usage

Despite the common name Welsh Onion has nothing to do with Wales they are in fact probably from Asia and are regularly used as an ingredient in Asian cuisine. They are particularly important in China, Japan, and Korea, hence the other English name for this plant, Japanese bunching onion. Welsh onions can be used as a scallion or salad onion, would be, they are also quite often referred to as these but whether you sprinkle them raw over salads with all their vitamins intact or cook them in a stir fry, green onions have high levels of vitamins A and C and calcium along with compounds that promote heart health and may help prevent cancer, they may be the most nutritious onions you can grow.

    Welsh Onion Plants

    Posted by Richard Baker on 3rd Aug 2021

    The plants from Hooks Green seem to me exceptional. Strong, growing well and full of roots. Obviously balancing the size and the need to transport them is obviously a complex matter. The base pot size is therefore quite small, but it does mean that they need transplanting or planting out quite soon after arrival. The packing is brilliant, usually with a stake, holding the plants safely in the outer box but also light and recyclable. The plants come very quickly but still need a water soon after arrival. The postage and packing cost is a great facility but it is more economical the more plants you order. Highly recommended indeed.
