One of my favorite things about this time of year is for a few short weeks, my Pineapple sage (Salvia elegans) and Bog Salvia (Salvia uliginosa) are in bloom at the same time.
Pineapple sage can pretty much deal. Drought tolerant, heat tolerant, grows in clay soil… And it gets nice and big: 5’x’5. The leaves smell like pineapples. The red flowers start at the very end of summer and last all fall.
Bog salvia likes a lot of water (and Pineapple sage happily adapts). It can get to be 6′ tall but probably not more than 3′ wide. The cool thing that I’ve discovered is that it will flow in around your other plants and you get this beautiful effect of the blue flowers weaving in through other flowers or foliage.
These are growing in a raised bed where they have completely filled in around a lemon tree, a rosebush, and a columnar apple tree. I cut them both down almost to the ground the first week of the year when I prune my roses and don’t touch them the rest of the year. Butterflies and hummingbirds love them both.
