I am wanting to start a new garden bed, but many of the plants I want I can only find as seed (it's a theme garden, where all the plants will have beach/lake/maritime names, like shell leaf beardtongue and perennial geranium "splish splash"). Is it too late in the season to start them now? I am also going to add some daylilies (like beach music), iris (like toy boat) and hosta (sooo many choices) but those will be already started so I'm not too worried about them. I can water them in and they will do fine. I'm just worried the seeds will be starting out too late to make it through winter.
