Canna Seeds - Red - Wonderful foliage , Intense red color - Dark purple to near black leaves. Give your garden a tropical look !
Canna Red (Canna x Generalis) - Growing Cannas from Canna seeds is extremely rewarding and brings a striking perennial to the landscape that gives a full season of color. This Canna Lily can grow 24 - 30 inches tall and gives a wonderful display with its colorful foliage and blooms of intense red color. Canna seed is one of the largest flower seeds you will find at only 5 seeds per gram. Due to this factor, it is best to soak the flower seeds for 24 - 48 hours before planting to soften the seed coat. For even faster germination, file or nick the Canna Lily seeds before planting. Canna seeds should germinate in 10 - 20 days at 76 - 80F.
Cut old spent flowers and seed pods to encourage repeated flowering late into the autumn season. Canna plants should be spaced 9 - 18 inches apart depending on the size of the varieties used and the effect desired. In dry weather, watering Canna Lily plants once a week will insure a stronger growth. Another common name for Canna is Indian Shot or Canna Lily. Canna grows best in wet locations. Nice for a water's edge, plantings near ponds and pools work well. Not hardy north of zone 7, but makes an excellent annual flowering plant. This Canna variety will often bloom in just 90 days after planting flower seeds.
DETAIL GROWING INFORMATION
Planting canna seeds
For those who have not grown Canna from seed before, this may be a good time to start giving it some thought. The best time to plant the seeds is dependant on the facilities that you have available.
If you have access to a propagator or heated greenhouse then seed can be sown as early as mid-January to early February. Given these conditions and reasonable weather in late spring and early summer we have sometimes had young seedlings burst into flower as early as mid-June.
If you are growing in a warm room, don't sow too early, unless you can provide heat and light to keep the young plants growing nicely through till April-May, when you will be able to transfer them to the unheated greenhouse, as they will likely be too tall for a cold frame.
Cannas have an extremely hard protective seed coat that is impermeable to water, so they will not germinate without some assistance. You can help the germination process by removing a bit of the seed coat through a process called scarification prior to planting.
Once canna seeds have been scarified, they are easy to grow. Only the tiniest amount needs to be exposed and it is better to file too little away than too much. If you look at the seed carefully, you will see a scar (hylem). It is through here that the growing shoot will break through. You should file the coat on the opposite side to the scar in order to avoid damage to the embryo.
How you go about scarification (nicking) is quite easy. There are several variations on this, and everybody develops their favourite method.
Take a piece of sandpaper and sand the end of the seed until you get through the black seed coat.
An alternative is holding them in a pair of pliers and using a file, carefully cutting into the coat until you reach the white endocarp within the seed,Or you may want to use a grinding wheel, which I use (a cheap Chinese import). I hold the seed in a pair of pliers and hold the seed to the grinding wheel just for a few seconds, until I see white.
Which ever method you use, you'll know that you're through when you see the white endosperm. Basically, what you're trying to do is make a hole in the seed coat so that water can get through.
Again, there are several techniques available to germinate the seed.
I get some very warm water, almost hot and I put the seeds in for 48 hours or until I see the embryo coming out one end. I change the water twice daily to keep it from souring.
Another popular approach is to add some vermiculite to a plastic bag, add water to moisten and then add the seeds. The bag is not locked so that air can circulate. The bag is kept in warm conditions, an incubatotor or airing cupboard. The disadvantage with this is that after a while the water will sour, and while I have used this method in the past I now prefer the first one, because changing the water requires a change of vermiculite as well, and vermiculite costs money!
Some plant the seeds directly into small pots and water, waiting until a growth of some sort is seen, this might be a growing leaf or a white embryo, depending on the position the seed was placed in the pot. As some seeds will not germinate I always feel reluctant to spend on pot and compost until I see the seed has germinated. Call me a skinflint if you want, I just blame my parents!
Once you see the white embryo coming out you can pot them up. I use 2 inch peat pots filled with a peat-based compost with added fertilizer. I plant the seeds 1/2 inch deep with the embryo pointing downhill, water well and put in direct light.
Maintain a temperature of 21-24Â°C (70 to 75Â°F). In a few days (5-6) you should see growth. As the plants begin to actively grow, the soil will dry out quickly, so check daily and water when needed. Keep the growing medium moist, and do not over-water, as more seedlings die from that cause than from neglect.
Depending on how long a growing period the seedling has indoors it may need planting into a larger pot, and the advantage of the initial peat pot is that this just means planting the whole pot, thus no root disturbance.
Gradually harden off the cannas and transplant them outside, adding plenty of compost to the soil, following the last-frost date. They should flower about 90 to 120 days after the seed was sown.
