I bought 2 types of verbena (Homestead Purple and Apple Blossom) about 1-1/2 years ago from a mail order source . When I received them, they had a few blooms then none at all very soon afterwards. I live in Miami, Florida - Zone 10. The verbenas are in a large container and I have added new potting soil. The foliage has been healthy and green. I cut the stems back recently as they were getting leggy, and new foliage has grown - but still no blossoms. I use an organic fertilizer 2 or 3 times a year. I have read that verbenas can withstand draught conditions, but they don't look very healthy when there is not enough rainfall - so I supplement with watering 2 or 3 times a week. The container is on my back porch (west sun exposure). Any suggestions on how to get these babies blooming would be most appreciated. Thank you so much. Happy gardening to all!
