I take the shears to them once the flowers have mostly gone over. There are always more buds in the crowns ready to take over. Mine flowered right through last winter, never completely without flowers!
Hi, I bought some wallflowers at the weekend to brighten up a corner of the front garden. I haven't had these particular ones before but was inspired to give them a go by many people on GT who rave about them. I'm a bit late to the #bowlesmauve party 😊💜 Have a terrific Tuesday 😃 #wallflower #bowlesmauve #purple #inspired
