Care Tips Water regularly during growing season and stake tall varieties. Lift after first frosts. If you're growing in containers, stop watering at the end of summer and bring the pots indoors for the winter. Leave them in their pots or take them out and dry. Put them out again next spring after danger of night frosts has passed. Find out more advice about how to plant and grow gladioli corms.
Flowering May - June
Vase Life Remove the bottom leaves. Some people remove the top of the spike to encourage more flower but I think this is a shame as the twists and turns of the spike are part of the appeal.

Mine turned out to be the wrong colour, due to a mixup in labelling, but having them replaced later in the year so full marks for after sales

These were stunning - I saw them on a recent trip to Italy growing wild on the roadside and the ones I grew from Sarah Raven were similar in very detail. I just hope they come again and again!!

I planted these last year in my rather challenging wild patch, long grass,ground elder and moss, then forgot about them.
Every bulb is now flowering and they look so beautiful. I will be buying more
