Approx 1/3+ of the standard sunflowers and nearly all of the dwarf varieties had multiple heads, and continued getting more buds, one had 12+ tiny flowerheads (these are all annuals). I got very few normal size sunflower heads because of this.
Why did this happen? If I use seeds from them will it grow more of the ones with multiple heads?Why did so many Sunflowers split into multiple heads? and if I plant their seeds will it make more like that?
The wild type of the annual sunflower (Helianthus annuus) is characterized as having multiple small heads. Through selective breeding, a domestic type bearing a single large head has been developed. These are the ';common'; types that most people are familiar with. In addition, many other variations, including dwarfs and additional color variants, have been developed. If you use seeds from these cultivars, it is likely that the resulting plants will appear similar to the original plants, unless there has been some exchange of genetic information (ie. cross-pollination), in which case who knows what your next generation of sunflowers may look like.
