With a controlled upright habit, Lanai Upright verbena are ideal for 4-inch, high-density production. They are frost tolerant for early spring sales and low-energy production. New to the series for 2012 are Rose with Eye, Blue with Eye, and Pink.


Select a porous media that drains well. A pre-plant charge of micro and macro nutrients is recommended. Thoroughly water the rooted cuttings until media is saturated. Moisten finish container media until wet to the touch, but not saturated. Dibble a small hole to prevent breaking of delicate roots when transplanting rooted cuttings.


Begin fertilizing after plants have rooted out. Constant liquid feed with a nitrate-based fertilizer at 200- to 250-ppm nitrogen. Feeds high in ammonium may promote soft growth.


Initially provide 1,500 to 2,000 foot-candles to a newly transplanted crop. Full sun can be tolerated once a root system is established.


Large containers and baskets may require pinching two weeks after transplant to promote fuller plants. Florel (ethephon) can be used for a chemical pinch. Apply Florel at 250 ppm two weeks after transplant. A second application two weeks later may be needed on larger containers.
