We cannot think of any plant that draws more hummingbirds than the hardy upright sinningias. Most of these are Sinningia selovii hybrids that come in a range of colors from yellow to orange to red. We have them ringing our full sun patio, which results in a non-stop show of hummingbirds.
We’ve got a different take on going tubing. For us, tubing is something we do, starting in mid-June each summer, when we sit and enjoy our patch of Sinningia tubiflora. This amazing South American (Argentina, Uruguay, and Paraguay) gesneriad (African violet cousin) forms masses of underground potato-like tubers, which produce these amazing stalks of sweetly fragrant flowers for months each summer. These are reportedly pollinated by sphinx months. Sinningia tubiflora is insanely drought resistant and so easy to grow if given enough sun. Since it forms a large mass, don’t plant it near smaller, less-aggressive neighbors.
Here’s a recent photo from the garden of one of our favorite full sun, summer-flowering perennials, Sinningia ‘Arkansas Bells’. This amazing African violet relative thrives with cactus and agaves in our full sun rock garden, flowering from April until September, during which time, the hummingbirds have to wait their turn. We don’t currently offer this because not enough folks purchased it last time, which drives us a little nuts! It’s only winter hardy to 5 degrees F in the ground, but makes a superb container plant in colder zones. So, why do more people not buy this? Please convince us to propagate some more since it is so wonderful.
