Description

Rich, luxurious crimson velvet gladiolus which is now perennial in our garden. We have built up groves of the taller glads as minarets and towers, either to contrast or to match a dahlia partner. We mulch them deeply over the winter (as we do the dahlias) and with this treatment, they have turned out to be reliably perennial.

Care Tips

Water regularly during growing season and stake tall varieties. 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.
