After reading that it could be invasive, I relegated it to the back fence and proceeded to totally ignore it for three years. It's growing great in dry shade. I got some more for the area this fall, and it can invade back there all it wants!

I have S. guaranitica "Black and Blue" plant in a semi-sun area and it thrives! It is growing pretty compact and bushy and as of now - Sep 24th, in Norfolk VA. it is completely covered in flowers. I am thrilled it does so well without getting "leggy" in a more shaded area.

I gotta be neutral on this plant because as others have said, they will grow weedy and try to take over nearby flower bed but if you are plating them as standalone without having other smaller size plants nearby, then this makes a nice & unique flowers in your garden (they call them blue but I say they are dark purple). Haven't seen hummers on them as they are planted on the side of the house where I only go to water the plants. I do say they are hardier and more pest-free than the red varieties that attract caterpillars, snails, leafspot and other diseases. Plant break easily when cultivating nearby or moving, but it will grow new branches in no time and become full again.
This one does spread, but hasn't totally taken over. It's well worth having just for the hummingbirds. There is always at least one working ours. I'm going to move them to an area right outside our breakfast room windows where there will be lots of room and we'll have a better view of the hummers.

This is the most invasive plant I've ever encountered. It's up there with mint. It spreads by underground runners and has taken over a huge bed and crowded out every other plant in that bed. I am not struggling to prevent it from jumping to the next bed. The runners are going under a stone path and inching into the rose bed. I've pulled up tons of it, but if you leave a bit of the broken runner in the ground, you get new plants. I really wish I'd never planted this plant!

In the spring I planted 4 four-inch tall plants ('Sapphire') in a dry, sunny area of my garden where I couldn't get much to grow. They rewarded me with amazing growth by summer, reaching almost 5 feet tall. In my garden, they bloom constantly until the first freeze. The flowers are gorgeous, and the scent of the leaves is amazing. And they reseed very nicely as well. They enjoy a good drink once a week unless it's really hot- then an extra watering or two keeps them happy.
One of my favorite activities is watching all the bees and hummingbirds flock around these plants. It's really funny to see the huge bumblebees try to get to the nectar of these narrow flowers. Many bees 'cheat' to get to the nectar; they make a small hole in the calyx of the flower to get to it. I have enough hummingbirds to ensure pollination of them, though!

This salvia, unlike most other salvias, prefers shade and moisture, but will do OK in full sun with good moisture. It is hardy to at least zone 7. A hummingbird favorite. It multiplies by sending out new runners from parent. If you want a single large specimen, remove these runners. In zone 8 it blooms almost continuously from April till the temp goes below 27F. There is also a sky blue form called 'Argentina Skies', does not multiply fast by runners.

This is a plant that I've been surprised to find came back strongly (foliage, that is--too early to tell about bloom)in the spring. It is a nice plant--has performed relatively well for me in high desert, Zone 7, partial shade conditions.
Five years later, in the spring of 2007, my anise sages continue to thrive. Since we provided more sun for them (cut down several large trees), they seem even happier--healthier spread, better bloom.. They even survived this past winter, the worst one we've had in 30 years. Also, I've successfully propagated a couple of them through cuttings.
