I have lost of empty spaces in our newly cleared garden and a limited budget so trying to decide how to use my funds most effectively. Im quite happy and keen to grow some perennials/ grasses on my wish list from seed but want to be realistic about how quickly I will get garden-ready plants (partly re the space and time etc needed for lots of potting on). This seems to be the sort of practical information which isn't readily available so am hoping to pick your brains as to how long any if the following will take to go from seed to garden please or whether plug plants or divisions/cuttings may be the route to go?
Penisetums Hamelyn and Little Bunny
Helianthus Lemon Queen
Phlomis russelina and Amazone
