I sowed garlic chives yesterday. I hope to plant alternately with normal chives as an edging.
I have never tasted them but I suppose they will have a "garlicky" flavour?
Gralic chives are a flat leaf.
They do have a very delicate garlicky flavour. They are often called chinese chives.
Many people grow garlic chives for the flowers in cut flower packs and the flowers are often used by chefs as part of those edible flowers.
For propagting normal chives, have done this many times, just put a spade through the middle and plant the clump.
Would not cut them right down now, as this is the time they are pushing through their growth for the year. If you need some chives for the kitchen, cut a portion off, not the whole clump.
