flowering from seed

Do you want to enjoy a beautiful flower garden without spending a ton of money? You can save money on flowers for your garden by buying more seeds and fewer plants. Perennial flowers grown from seed might not bloom during their first growing season, so it’s important to have a little patience with them. On the other hand, annual flowers should bloom as they go through their lifecycle over a growing season, and some annuals might even self-seed to grow new plants the next year. Here are 14 flowers that are among the easiest to grow from seed.

These flowers have a lovely sweet fragrance and bloom from around April to June. You can sow the seeds directly in your garden a few weeks before your final frost date, or start them indoors roughly six weeks before your projected last frost. The plants will decline in the summer heat, during which you can cut them back by about half. This might promote additional blooming in the fall. Or you can sow more seeds in August for fall-blooming plants.

These flowers make a good ground cover for a spot that gets a lot of sun. They are highly tolerant of drought and require little maintenance. They’re even deer-resistant and typically don’t have pest or disease problems as long as their soil has good drainage. Sow your seeds directly in the garden after your last frost, or start them indoors. Expect blooms starting in the summer and lasting until frost arrives in the fall. You can deadhead the flowers to encourage further blooming, or leave some of the spent blooms to promote self-seeding.

This vine is often grown on trellises or arbors. It is an annual, and when started from seed it can take until the end of summer to bloom. However, if you start the seeds indoors about six weeks before your projected last frost date, they’ll start blooming earlier in the growing season than if you directly sow them in your garden. Once the plant is established in your garden, it will self-seed and come back on its own year after year. Water your plant around once a week to ensure even moisture, and use a low-nitrogen fertilizer monthly or as needed during the growing season.

These annuals are climbers and make nice cut flowers. They do best in cool soil and will decline in hot, humid summers. Start seeds indoors six to eight weeks prior to your final frost date to maximize the plant’s blooming period before the hot weather takes hold. Keep the soil evenly moist via rainfall and supplemental watering. And add compost or fertilizer during the growing season, especially if you have poor soil.

Do you want to go from seed to bud quicker and cheaper? A faster, space saving and economical way to grow is the no veg, seed to flower, 12-12 light cycle method.

Everything to which you would pay attention in a normal grow remains unchanged and are still just as important. pH and water quality, nutrient mixing, pest control, grow medium conditions, EC and ppm all still play their major roles in the dankness and weight of your finished product.


Growing with a 12-12 photoperiod is a solution to space and resource problems. This method eliminates the vegetation phase of growth and forces the plant to go straight into flower from a seedling. Yields are lower than that of a regularly grown cannabis plant, but results are obtained much faster, with a few advantages.

Growing 12-12 is as simple as changing the timing on your light cycles, giving your plants equal amounts of day and night right from when they sprout. The plants will look different to a cannabis plant that goes through vegetative growth. Photosensitive hormones in cannabis make the highest point the largest cola. This method all but guarantees only main bud growth on every small plant. Essentially you will be growing a cola with a few short, budded side branches – with the plant basically being a bud in itself. Be sure to stake your plants.


This seedling took nearly 4 months from seed to harvest under about 150W of fluorescent lights and yielded only 1/2 of an ounce.

Plants reward you for giving them a little more time to grow. For example, a solid 4 weeks of 18/6 before 12/12 creates plants that are ready to harvest around the same time as a plant given 12/12 from seed (3-4 months, depending on the strain), but significantly bigger yields.

12/12 from Seed – What You Need to Know

There’s just one major problem… 12/12 from seed often causes stunted growth and small yields. This results in yields that are often less than 1 ounce per plant, even under strong grow lights.

Here are those same plants a month later after they started making buds (plants double or triple in height after the switch to 12/12, especially young plants)

If you haven’t heard this term before, “12/12 from seed” means giving your cannabis seedling 12 hours of light and 12 hours of dark each day from the moment of germination. Providing a 12/12 light schedule initiates the flowering stage and causes cannabis plants to start making buds. The idea of this technique is to get seedlings to start flowering as quickly as possible to reduce the time to harvest. Once a plant has started flowering, most strains are ready to harvest within 12 weeks. The sooner you get a plant to start flowering, the sooner you get to harvest.
