The little sunflower that could – the beach sunflower


Groundcovers are always in demand as we attempt to cover certain landscape space with something other than turfgrass.  Groundcovers reduce labor (mowing) and inputs such as fertilizer and supplemental water that some grass requires.  Bottom-line, groundcovers fill in landscape areas with low-maintenance color and/or texture.  One of the best groundcovers available in our area that I would recommend is the  beach sunflower.  

The beach (or dune) sunflower is a wonderful groundcover that offers both quick coverage and abundant flowering.  Imagine a carpet of perfect miniature sunflowers with three-inch wide flower heads combined with green foliage which will only get about eighteen inches tall, but spread from four foot to eight feet wide.  Well adapted to coastal full-sun areas, the perennial beach sunflower spreads by above-ground runners and seeds.  Both salt-tolerant and drought-tolerant,  over irrigation will cause this plant to suffer, so water infrequently.  The beach sunflower propagates easily from seed or cuttings.    In addition to planting in mass as a groundcover, use beach sunflowers so that they cascade down a wall.  Space plants from three to four feet apart – they will grow together quickly!

You should get at least two good years of flowering and luxuriant foliage from your initial plantings.  After that point you will notice that these sunflowers will decline and need to be replanted.  Seedlings may have already begun to repopulate the open areas and taken care of the rejuvenation for you.  Besides the classic yellow colored petals, there are varieties with shades of copper-red, pinkish, orange and purple-colored flower heads. In addition to the attractive flowers, the blossoms  are also very attractive to  butterflies and other pollinators. 

Beach sunflowers will produce most of their flowering in the fall, winter and spring.  This gem is truly a treasured plant - both useful and attractive!  For more information on all types of groundcovers, please call our Master Gardener volunteers on the Plant Lifeline on Mondays, Wednesdays and Fridays from 1 to 4 pm at 764-4340 for gardening help and insight into their role as an Extension volunteer.  Don't forget to visit our other County Plant Clinics in the area.  Please check this link for a complete list of site locations, dates and times - http://charlotte.ifas.ufl.edu/horticulture/Plant%20Clinics%20Schedule.pdf.
