I am interested in your indigo spires. I can trade you either leucantha or uliginosa.

My favorite salvia the last couple years is "Black and Blue" Salvia. The hummingbirds love it and I just bought a couple today at $4.99 each at Fred Meyer. I have seen them at specialty nurseries for 8.99 and up.

Ugh! I hate it when this happens! Always happens to my S. Leucantha, usually after a downpour of rain while its at over 3 feet. What I do is I stake around it and tie just like Westelle mentioned. It works for a bit but once it gets at 5 feet or so, the it grows out and over and doesnt look to well. Im going to prune that sucker to the ground completely this year. The small short dead canes from previous prunings I have noticed are sort of creating the plant to be 'pushed away' from the middle area, making the outside branches more prone to laying flat.

I have never had to stake mine, nor do I know anyone down here that has had that problem. Maybe they are not getting enough sunlight. Indigo Spires states: Culture Indigo Spires tends to keep growing and growing and then falling over under its own weight. Constant pruning and pinching will keep it in bounds, and removing the flower spikes after most of the flowers have dropped off will encourage more blooming. Light: This salvia does best in full sun, but does okay in part shade, too. Moisture: Indigo Spires needs regular watering to be at its best, but can tolerate drought if it has to. Hardiness: USDA Zones 7 - 11. Indigo Spires dies to the ground after frost and returns reliably in spring. Propagation: Indigo Spires is a sterile hybrid, so don't bother with seeds. Fortunately, it is very easy to root from cuttings.
