New gardener -flowering bulbs questions..
Hi New gardener here. I am looking to do up some sections of our North facing drive. After my earlier regarding re plant (I got acer palmatum, Hebe and another one which I can't remember name off). e, I am now looking to add some colour in between these. 1. Do these bulbs only survive one season? Do I need to remove them at end of summer or they automatically die down? 2. Any summer/autumn n flowering bulbs which behave like tulips in that they grow automatically and which can be left outside over winter.... Ta.
