A butterfly and bee-friendly classic, Gladioli corms are easy to grow and thieve in all soil types, in full sun or partial shade. When supplying corms, we measure the circumference of the bulb and display this is cm, making it easier for you to select the variety most suitable for you. Supplied direct to your door, in breathable bags to ensure they arrive fresh and ready to plant on arrival in either borders, beds or containers. Available to order online from December through to May, with delivery from mid-January through to May, depending on variety chosen.

First-size 8/10cm corms - Our smallest sized corms, perfect for planting in larger groups within the border where they will create a superb value for money display, with flowers a little smaller than the largest sized bulbs.

Border 10/12cm corms - An excellent choice for borders where they will produce good sized, vibrant flowers on sturdy and reliable stems, with flowers a little larger than 8/10cm corms. An excellent choice for mass planting.

Top-size12/14cm corms - Our premium sized Gladioli corms for producing exhibition quality and sized flowers, the largest flowers possible. We recommend using 12/14cm for Giant-flowering Gladioli varieties and mixtures when you are looking for optimum flower size. Their stronger stems will require some support, such as staking the stems.

Plant gladioli corms about 10-15cm deep and about 10-15cm apart, in fertile/well drained soil. When planting in a heavy soil, place some sand underneath each corm to help with drainage.

You can water regularly as the growth begins to appear and you can dead head when flowers begin to die off, though make sure to leave foliage to grow throughout the summer. In late autumn when frosty and cold nights are likely to return, you should lift and dry the corms and store over the winter in a frost free shed/garage until ready to plant again next year.
