Ok... if there's a prob. just stop me, lol. One of the main things to do is keep your plants deadheaded, (cut off old blooms), either it will form new buds or if a seasonal won't (ie peonies, iris, perennial alysssum, spring phlox, Pix2 and pix5, etc.) Realize that you need approx4-6 wks for new blooms, sometimes less.
Rebloomers:Pix 1 above, Verbascum phoenicium; pix 3&4 Centaurea montana; Daisies, Veronica spicata, Salvias, Achilea (yarrows); Osteospurmum, many Campanula, Scabiosa, Snapdragon, Malva, many Dianthus (except spring bloomers), Echinacea, Gaura, Geranium Johnson's Blue and Rozanne, Geum, Heuchera, Penstemon Pike's Peak Purple and Red Rocks, Rudbeckias, Anthemis, Aquilegia, Armeria, Aster, Boltonia, Buddleja, Catanche, Centranthus, Centaurea, Coreopsis, Knautia, Lavatera, Physostegia, and Ratibida. And there are probably more, but these are flowers I have experience with. Yes, I used botanical names, lol. I didn't list the fall bloomers as they are obvious late bloomers.
Many from the list above will bloom the whole season. My daisies, I like to cut within inches of the ground that way I get 2 blooms for the one cut, I snip just above a node.
Pix1: Osteospurmum
Pix2: Knautia, sorry a bit out of focus
Pix3: Scabiosa
Pix4: top to right, sunflowers,Daisy, Penstemon Rocky Mt Blue (only spring), Lavendula, Veronica. Malva
Pix5: Snapdragons (Rocket Series at 36" and Lavender (also blooms the whole season).
Does that help?
