Gardeners' Notes:


On Sep 22, 2009, darylmitchell from Saskatoon, SK (Zone 3a) wrote:

These are very attractive sunflowers and easy to grow from seed. We ended up with several towering plants almost 12 feet tall, with many yellow-orange flowers. Unfortunately, about half of them got blown over by the wind. Those that blew over but remained rooted still kept growing - the tips simply turned upward. I would recommend staking these unless in a sheltered location.

By mid August the sunflowers are 6 ft tall and in full bloom. I often sit in the garden around 7 a.m. in a white wicker chair watching a pair of Goldfinches perched on the tops of the larger blooms. They love sunflowers. Apparently the natural food and their blending into the scenery make the birds very prone to finding sunflowers as a food source. The Goldfinches must be the main source of spreading the seeds. This spring we have 10 times as many sunflower sprouts coming up in our garden and a even in the gravel driveway on the outer side of the fence. I'm going to have to tell the neighbors to come and get some for themselves.

Medium sized Multi-Bloom sunflowers in fall colours.

These sunflower grow to about 6 feet in height. Some as tall as 8 feet and some shorter around 5 feet. They produce a few blooms per plant in many different colours and sizes. This is not a particular plant but a blend of Hybrid sunflowers in fall colours. They do ok as a cut flower and are pollenless. The stems are not as strong as other sunflowers so this one might need to be staked in windy conditions. All in all not a bad blend of hybrid sunflowers.
