If you have followed me for any length of time, you know I grow sunflowers every summer. I heard from Melissa, a childhood friend of mine who follows my blog. She asked for a list of my favorite varieties of sunflowers. I think there may be more of you out there who might like to plant sunflowers this summer so I put this Sunflower Growing Guide together for all of my readers. Please share this post with your fellow gardening friends! FYI - I grow in western Massachusetts. All photos by me taken either at our Farmhouse Garden or at our Sunflower Field (from a few years ago).
First off - there are two companies I buy seeds from. My longtime supplier has been Johnny's Selected Seeds in Maine. They ship amazingly quickly from Maine. No minimums and they have some mixed variety packs for those of you with small gardens.
My second supplier (a recent find) is SunflowerSelections in California. I heard about them through this NY Times article. I have purchased from them since 2012 and have nothing but good things to say about the company, service and the varieties they offer. SunflowerSelections is actually a subsidiary of NuFlowers, a breeder of sunflower varieties. The only downfall is their packs are 100 seeds and there is a $15.00 minimum. Their website is set up to sort by colors, branching, single stem, and more.
So here are some of my thoughts about growing sunflowers. This is what I have learned from many years of growing them.
1.You need sun! Shade doesn't work for them and long days of sun will yield much better flowers.
2. Although you can plant sunflowers early in the season, I wait until the middle to end of June to plant. This will give me flowers through frost. I have planted as late as the beginning of August and still gotten flowers - they are smaller because of the shortening days at that time of year.
3. There are two kinds of sunflowers - Branching (many flowers per plant) and Single Stem (one flower per plant). I prefer the branching sunflowers to the single varieties (ProCut, Sunbright, and Sunrich strains). You get more sunflower blossoms per seed and they have a wild and unruly appearance which really appeals to me.
4. Florists and growers usually plant the single varieties because they are reliable, are sturdy, and ship well. For the home gardener (me) they are a bit of a disappointment because they take up room and I only get one flower per stem. That said - they are very quick to bloom so I usually plant some so I get flowers quickly.
5. Once my plants are about 8 inches tall, I mulch the heck out of them to hold the water in the soil and keep the weeds down. Once they get going, they grow like crazy and shade out most of the weeds.
6. I don't fertilize my sunflowers. I have basic garden soil and the mulch from the previous year gets tilled in. I do add manure from my chickens and the sheep though every other year or so.
7. Don't crowd the sunflowers. If you do, they will be stunted and not thrive. I plant about 2 to 3 seeds every 12" or so. That gives me insurance in case the birds or mice eat the seeds.
8. Sunflowers tend to not transplant well. Plant them where you want them and be patient. They will grow as long as they have sun.
9. There are dwarf varieties of sunflowers available but I don't grow them. I did once and they just didn't seem right. I am fortunate to have lots of sun and space but if you are tight on space, check out these selections via SunflowerSelections.
10. Most of the branching sunflowers have one very large top flower. If you pinch (or harvest) the top flower, the lower branches will grow longer stems and the flowers will be bigger.
11. If you are looking to grow the giant sunflowers for bird seed, I do suggest you plant them as early as possible. They need a long time to grow huge and win any contests. If you plant them later, they will be shorter and the heads will be smaller. I like the variety called Mammoth Russian available from Burpee.
Here are the Sunflower varieties I highly recommend with links to each supplier who stocks the seeds. I have described why I enjoy each of the varieties. Don't wait to order your seeds because they often run out of popular varieties. The variety is BELOW each photo.
|Both photos - Autumn Beauty|
|Moulin Rouge Sunflower|
Joker - Branching. I love this multi-colored sunflower. It is one of the first to bloom. The center is edged with a fringe of teeny petals. The outer petals are long. Once in a while, there will be a plant that has different looking blooms on each branch. It lasts a long time in a vase and is quite sturdy. Not too tall but definitely not short.
|Orange Ruffles Sunflower|
Orange Ruffles - Branching. This sunflower was new to me last year and it rocked! Similar to The Joker and Greenburst, it has a brown center with a fringe of mini yellow petals. Seriously gorgeous.
|Greenburst Sunflower - Top Flower|
|Small Greenburst Bloom from one of the bottom branches|
Greenburst - Branching. This sunflower was new to me last year and I am in love! Reminiscent of Sungold, it has a tight chartreuse center surrounded by hundreds of tiny petals. The outer edge of the flower has slim long petals. The top bloom is big (8") if you let it grow. If you cut it off early, the smaller lower branches will produce bigger pretty (although smaller) blooms. Long vase life.
Sunbright - A single stem variety that is the classic sunflower. Quick to bloom. I always plant these so I have big blooms quickly. This variety is often grown commercially as is the Pro-Cut varieties which I am not highlighting here in this Planting Guide.
|American Giant Sunflower|
American Giant - This is the classic GIANT sunflower. One giant head per stem. These plants are like small trees by the end of the season. It is best to give them lots and lots of room to grow. They will shade out other plants so if you have a spot, away from your regular garden that has good sun - plant a few there for fun. You will have a giant seed head to feed to the birds. You could also plant a "sunflower house" for your kids and grandkids.
Sungold - Branching. You need to have a long growing season for this gorgeous, puffy sunflower. They are always the last to bloom in my garden and I usually plant them first! The top flower will be the largest. Once you cut the top flower (usually 10" across) with its short stem, the lower flowers will grow with longer stems. A few years, the frost got mine before they bloomed, so plant them first!
|Holiday Sunflower backed by Autumn Beauty|
Holiday - I love this sunflower for its vigorous nature. You will get so many blooms off each plant. The blooms are not very big - about 5" or so. It does drop a lot of pollen (for those of you who are clean freaks). The blooms develop in the vase nicely.
|Golden Cheer Sunflower|
|Stella Gold Sunflower|
Above is a mixed bouquet from last summer. Flowers included are: Autumn Beauty, Moulin Rouge, Greenburst. I like mixing in some of the over mature "done" sunflowers for interest.
I hope you will try to grow some sunflowers this summer in your garden or along the edge of your yard.
