These are not the sunflower I was seeking, I followed directions, unfortunately following directions, nothing happened, wasted time on them, I finally received one flower I took it upon myself o plant the seed indoor in a small pot of soil, It grew wonderfully, , It was beautiful flower, but not what I was seeking, the ones that get seeds in them ,

I’ve planted this variety from this company and it has a good germination rate (100% for me, ymmv).

A couple of them grew fairly tall but never got any seeds from them. And, it is weird but these ones will not follow the sun as all the others do. Why is that?

These were easy to plant, easy to care for, and they grew beautifully.I planted in late June and got great blooms through September/October. I drew a line in the dirt with my finger, dropped a messy line of seeds, and covered it up. I live somewhere pretty cloudy, but final growth heights still ranged from 5 ft to 15 ft, directly dependent on the amount of sun each spot got.I will be buying again, as my local wildlife are gobbling up the fresh seeds, which is another major plus in my eyes.10/10 would recommend.

As an avid gardener, I'm always on the lookout for unique and beautiful plants to add to my garden. When I discovered Mammoth Sunflower Seeds, I knew I had found something special. These sunflowers not only provide a stunning visual impact but also serve an important ecological purpose in attracting pollinators.Upon receiving the seeds, I was pleased with the packaging and the clear planting instructions provided. I eagerly sowed the seeds in my garden, and within just a few days, the seedlings had sprouted. I was impressed by the vigor and health of the young plants.As the weeks went by, these Mammoth Sunflowers began to live up to their name. The stalks grew tall and strong, ultimately reaching heights of up to 12 feet! The gigantic flower heads, with their radiant golden-yellow petals and deep chocolate-brown centers, became the focal point of my garden. The sheer novelty of the towering plants brought a sense of awe and amazement to all who saw them.But it wasn't just the height of these sunflowers that made them a standout addition to my garden. I quickly noticed the increased activity of pollinators, including bees and butterflies, as they eagerly flocked to the sunflowers. This was a clear testament to the fact that Mammoth Sunflowers are not only beautiful but also extremely beneficial for the environment.In addition to their visual appeal and support for pollinators, these sunflowers produced an abundance of seeds that could be harvested for snacking or replanting the following year. This made the Mammoth Sunflower not only a stunning garden addition but a practical one as well.In conclusion, these Mammoth Sunflower Seeds exceeded my expectations in every way. From their impressive growth and striking appearance to their role in supporting pollinators, these sunflowers have become a permanent fixture in my garden. I highly recommend them to anyone looking to add a truly remarkable plant to their outdoor space. Happy gardening!
