Red Sunflowers


            Red Sunflowers    

                                        Sunflower – Prado Red

F1) Prado Red is one of the first sunflowers to bloom, making it an ideal choice for home gardens and for cut flower production. A multi-branched variety, Prado Red produces 15-20 beautiful deep red flowers per plant. It grows 5 1/2-6 feet tall, and each 14-21 inch branch is graced with a 5-6 inch flower. Slightly more sensitive to cold temperatures than other varieties, so wait until all danger of frost is past to plant.

   I found these at the

Territorial Seed Company

They have another variety which is almost totally red as well.

Sunflower – Double Dandy              

and yet another that is red with a very small yellow band just out from the seed pod.

Sunflower – Red Sun       

There is yet another one called:     

     Sunflower – Floristan

Italian White Sunflower

        Italian White Sunflower   

“Italian White’s” flowers are actually pale yellow to creamy white in color. Its 4 to 5 inch blooms are borne on branching stems making it an ideal cut flower. A unique heirloom addition to the flower garden.

The long, pale yellow petals of the Italian White lead to a chocolate-brown center making a strinkingly beautiful contrast. Multi-branching stems of this mid-size sunflower bear multitudes of 3-4 inch blooms. Strong, sturdy stems enable a longer blooming season than that of the typical sunflower. Cut flowers just before they open for a beautiful, long lasting bouquet.

Select sunny location with well-drained soil and plant after all danger of frost is past. For earlier blossoms, start indoors 5-7 weeks before last frost. Cultivate soil and firm over seed, keeping it moist.

Do not over water and do not fertilize.

10-20 days to germination.

H. cucumerifolius Creamy white blossoms surrounding a dark brown center make this variety unique. Although thought to be an heirloom variety brought to the US by European immigrants, it has also been observed as a wild desert variety. Regardless of its origin, Italian White’s multi-branching habit and 4 foot height offer a charming counterpoint to other sunflowers in your garden.

Special Directions for Short Season Climates

SOWING: Sow seeds directly outdoors after all danger of frost has passed. Seeds can also be sown earlier indoors in pots, 3 to 4 weeks before setting out. Cover seeds with ¼” fine soil. Provide indoor started seedlings with plenty of light.

THINNING & SPACING: Carefully thin or transplant young 2 to 3 inch seedlings to about a foot apart to allow for eventual growth.

GERMINATION: 10 to 20 days. Keep soil moderately moist during germination.

Mexican Sunflower

            Mexican Sunflower     

Ok, Ok, I can hear the fussing already.  Why is this here?  It is really a Tithonia and not a true sunflower.  Yet, it is most commonly called the Mexican Sunflower…so, I wanted to include it as well.

Mexican Sunflower           by Valerie (July 20, 2000)This annual is one of the easier to grow, reseeding itself about as faithfully as the common sunflowers that grow wild all over around here. The Mexican sunflower (Tithonia rotundifolia) doesn’t look anything like regular sunflowers, but is related. It does well in partial shade, but needs a little extra water, making it completely impractical for full sun exposure. The leaves are soft and velvet-like, with the short “fur” covering the stems as well. Even the large petals are velvet-like in appearance. The seeds tend to germinate late in the spring and the plants do not bloom until late summerThe flowers are magnificent, usually sporting a day-glo orange color, but ranging from deep gold to almost red. The center is usually gold. Like all sunflowers, this one usually opens the large outer petals, then the small flowers in the center open in sequential fashion, but once in a while a bloom will open center first, with the petals still rolled up in little tubes. Bees and butterflies spend a lot of time at these flowers. The seed heads are very spiny and I usually don’t collect the seeds, just smash the whole thing into the ground so they can germinate the following summer.

Autumn Beauty Sunflower

  Autumn Beauty Sunflower  

A lovely sunflower with flowers that bloom over a long season in a variety of autumnal shades of gold, bronze, brown and burgundy. These tall plants are covered with 5 inch blooms, some as many as 20. Flowers bloom over a long season and make an excellent cut flower.     

Sow seeds outdoors after all danger of frost has passed. Plant seeds ½” deep and 4″ apart. Germination takes 5 to 10 days. Remember to keep moderately moist during germination. Thin to 12″ apart when plants are 2 – 3″ tall. Grows 5 to 7 feet tall and likes full sun. Cut flowers often to encourage more blooms.

For something different than the regular common yellow sunflower, try this autumn beauty mix. Blooms in shades of yellow, red, orange, gold, purple, and bronze. Some have a ring of one color and a 2nd color in the center. Beautiful!!         Flowers are 4-8″ across and each plant will produce several flowers, so you can keep harvesting blooms. To further extend the bloom season, plant a set of seeds each week for about a month when spring planting time comes in your area.

Another hint for longer blooming season is to start these in pot indoors, and then move out after danger of frost.

Grows in any zone. Blooms in 60-90 days.

Sunflower Seed Catalogs

            Seed Catalogs      


Below is a list of various seed catalogs that I have used over the years.  This is only a partial list and if you browse you’ll find many many more.  It is just that I am familiar with and have done business with these companies in the past.


The Burpee company was founded in Philadelphia in 1876 by an 18 year-old with a passion for plants and animals and a mother willing to lend him $1000 dollars of “seed money” to get started in business. Within 25 years he had developed the largest, most progressive seed company in America. By 1915 we were mailing a million catalogues a year to America’s gardeners.


Since 1879, Harris Seeds has been providing gardeners the very best in flower seeds, vegetable seeds, plants and supplies.  Today, we continue that dedication with our easy to use website.  Welcome!


Welcome to our new e-commerce web site. Stokes Seeds is a distributor of flower, vegetable, herb and perennial seeds as well as many garden accessories to customers throughout North America. What makesStokes Seeds unique is our focus on quality garden seed and extensive growing information. Unlike most other seed companies we sell to both home gardeners and commercial growers.

Thompson and Morgan Seed Catalog

The history of horticulture in the UK is bench-marked with names that have become famous. Among the companies that have founded the country’s seed industry a few names still survive, although their independence has been surrendered. Yet, as one of the oldest firms in the business, Thompson & Morgan retains both its identity and its reputation for innovation and quality. It all began in a small garden behind a baker’s shop in Tavern Street, Ipswich, tended by William Thompson, the baker’s son. He started work by helping his father but, stricken with ill-health, he began studying botany and passionately cultivated the garden at the back of the shop in Ipswich, Suffolk, England. He was soon to acquire the name of the ‘baker botanist’. From the back garden he moved to a nursery at the edge of Ipswich and then to an even larger one. Eventually there were three Thompson nurseries in the town and William began to publish a magazine called ‘The English Flower Garden’.

When can I Plant Sunflowers?

  When can I Plant Sunflowers?    

The central rule of thumb is to plant after the last day of expected frost in your area.  Remember, sunflowers are frost sensitive.  A few days too early can mean the difference between a beautiful flower garden….and a disaster. 

Planting Zone Map

Learn what planting zone you live in:

Knowing your planting zone can be very useful when your are planning your garden and flower bed areas.

When you order plants online or through a catalog it is very useful for you to know what will have the best success in your zone. 

Most plants are marked with a zone number. Use this map to know what plants will do best in your zone.


Using the Zone Map is really very simple. Find your geographic location on the map. Observe the corresponding color to that location. Look at the map key. That number designates the zone in which you live. 

You should select products that can survive in your zone. Simply read the item description and you will find a either a zone number or a range of zones. The lower of the the two zone numbers tells you the lowest recommended zone in which that plant can survive. Sometimes, an item will thrive outside that zone area. Remember this is only a guide.

Diseases of Sunflowers

     Diseases of Sunflowers   

Helianthus annuus Rust (fungus – Puccinia helianthi): Small, dark brown, powdery pustules on the underside of leaves are surrounded by chlorotic areas [Photo #1]. Many of these pustules will cause the leaf to take on a brown appearance [Photo#2]. These heavily-infected leaves will die. A severe infection will reduce seed quality and yield. The use of resistant cultivars is the best control measure. In addition, residue from previous crops should be buried and volunteers should be controlled.

Powdery Mildew (fungus – Erysiphe cichoracearum): The symptoms are an extensive growth of white, powdery fungal mycelium on the upper leaf surface [Photo #3]. The disease usually occurs too late in the season to affect yield.

Downy Mildew (fungus – Plasmopara halstedii): The symptoms are pale green or yellowish areas spreading out from the midrib of leaves. With moist weather, there is the presence of a downy growth on the underside of the leaves. As the plants mature, there may be some wrinkling and distortion of the leaves [Photo #4] and plants are stunted. Angular leafspots can also be produced. The disease is seed and soilborne. Resistant varieties are available.

Mosaic (virus): Mottled areas are visible on newer leaves [Photo #5]. This virus symptom was seen in the Lower Rio Grande Valley. The virus has been tentatively identified as a member of the Carlavirus group. It occurs infrequently.

Charcoal Rot (fungus – Macrophomina phaseolina): The symptoms are premature ripening of stalks with a poorly filled head. At the base, the inside of the stem has a shredded appearance, and the fibers are covered with numerous, tiny black resting bodies of the fungus that resemble pepper flecks [Photo #6]. Varieties may differ in resistance to this disease.

Southern Blight (fungus – Sclerotium rolfsii): Plants wilt [Photo #7], then die. A bright, white mycelial growth can be seen at the base of the stalk [Photo #8]. The diagnosis is confirmed by presence of round, tan resting bodies of the fungus, which resemble mustard seeds. This fungus is soilborne.

Sclerotinia Wilt (fungus – Sclerotinia sclerotiorum): Plants wilt [Photo #9], then die. A bright, white mycelial growth can be seen at the base of the plant, along with considerable shredding of the stalk [Photo #10]. Black, irregularly-shaped resting bodies of the fungus are found within the stem [Photo #11]. A long crop rotation with non-susceptible crops, such as corn, sorghum or wheat, is the recommended control.

Rhizopus Head Rot (fungi – Rhizopus spp.): The head turns brown and becomes soft [Photo #12]. A gray mycelial growth will later develop [Photo #13]. Wet weather following flowering favors disease development, particularly if the heads are damaged by hail, birds, or insects. In Texas, head rot has been associated with larvae of the sunflower moth, Homoeosoma electellum. There is no control, although varieties with upright heads are more frequently infected than varieties with bending heads.
