Question and recommendation on perennial to plant?

Question and recommendation on perennial to plant?

Since you love the salvia, let it be your base plant. Go backward from the June bloom time and use bulbs to extend the bloom into February or March. Maybe start with Tommie Crocus, then early daffodils like February Gold, then Muscari neglectum, then species tulips like Tulipa clusiana that are perennial (not the regular tulips that don't last very many years past the first), then alliums, and German Irises.

Pick back up after July with hardy summer bulbs like Yellow Crocosmia and Surprise Lilies (Lycoris squamigera); then, for fall, sternbergia, Saffron Crocus and colchicum. You will have a rest period after these until the Tommie Crocus in late winter. Just about your only choice for bloom then is pansies or violas, Violas will give you the elegant look better than pansies. Plant them in October for bloom almost all winter in most places. Make sure the color violas you pick look good with the colors of the last few fall bulbs and the first few spring ones.

Plant your Salvia this spring when they become available, but kinda far apart like maybe 20-24". Decide what bulbs you want (these are just suggestions) from a mail-order catalog like mzbulb.com. Be sure to arrange the taller bulbs toward the back when planting those that will bloom together or consecutively. I believe you must order the Crocosmia in spring but the others should all be available as a fall order. Plant the fall-bloomers with a flag immediately, and plant the other with the violas in October. Cut the salvia back to about an 8" wide "pillow" (they should still be green) and fill in the gaps between all the salvia with the rest of the bulbs. Next year it should be glorious the whole year. In some places, if the violas are happy, they will reseed and after a few years you may not even need to replace them every October.
