had at least one sunflower; this includes balcony gardens. Mind you the
ones that I grew on the balcony where a miniature hybrid not the up to
twenty foot tall monster that grabs your attention in later summer.
Sunflower (Helianthus annuus ) is an annual herb that can withstand mild frost as a seedling, but requires at least 100 frost free days for normal development. Intolerant of shade, sunflowers can be successfully cultivated in many countries.
