In addition, from late spring to early fall, short terminal spikes (up to 8″) of bluish-purple flowers (each to 3/4″ wide) bloom. The two-lipped flowers have a snapdragon-like appearance. White, blue, light pink and bicolor flower cultivars are offered.

Furthermore, there are numerous Angelonia varieties to choose from. Some series feature the greatest blooms, while others have smaller plants (perfect for container culture). Seed-grown Angelonia cultivars are a relatively discovery in Angelonia breeding. This approach lowers production costs and provides high-quality plants at reasonable prices, as well as a wide range of color possibilities.

Moreover, Angelonia seeds produce blossoms throughout the summer, and the flower does not require deadheading to maintain blooming.

The Latin meaning of the genus name “Angelonia” is “Angelos.” The flower shape was regarded as an angel in the country of origin, South America. In the meantime, flower language means “unrequited love” or “previous lover.”

Guides for planting Angelonia? 

In fact, you can plant Angelonia from seeds that are sown early indoors or directly in the garden once frost has passed. Planting Angelonia plants is pretty simple if you follow a few simple steps.

Sowing Angelonia Seed Indoors

In the spring, use a seed starting kit to sow indoors 6-8 weeks before the final frost.

  • Step 1: Fill a clean, 3-inch planting container with drainage openings 3/4 inch above the container’s lip with a well-draining, sterile seed-starting medium.
  • Step 2: Place the Angelonia seeds in the center of the container, on the surface of the potting mix. It won’t germinate without light, so gently press it into the medium without covering it. You should sow Angelonia seeds ⅛ inch deep

  • Step 3: To keep the medium moist, cover the seeded pot with clear plastic. Place the container in a location that has the same amount of light as a bright, overcast day. Keep it out of direct sunlight. Make sure the soil temperature is between 70 and 75 degrees F.
  • Step 4: Check the pot every day. In 10-14 days, seedlings emerge.
  • Step 5: Provide lots of light on a sunny windowsill as soon as seedlings emerge, or grow seedlings 3 to 4 inches under fluorescent plant lights turned on 16 hours a day and at night you should turn them off for 8 hours. As the plants grow taller, the light intensity. Incandescent bulbs will not work since they will become too hot throughout the operation. To flourish most plants need darkness so don’t leave the lights on for more than 24 hours.
  • Step 6: When the seedling’s second set of true leaves appears, prepare a clean 4-inch container with drainage apertures for transplantation.
  • Step 7: With a dinner fork, loosen the seed starter mix around the seedling. Lift the seedling by its leaves and place it in the new container with care. To stabilize the hole, tamp the potting mix in and around it.
  • Step 8: Angelonia seedling plants must be “hardened off” before being planted in the garden. Moving young plants to a covered spot outside for a week can help acclimate them to outdoor conditions.

Sowing Angelonia seed Directly in the Garden

After all the threat of frost has passed, direct sow seeds in normal soil in full sun. Angelonia should be planted in full sun with well-drained soil.

What are the conditions for planting Angelonia ?

Viewed from different sides, Angelonia plants are a fixture in summer flower beds due to their hardy nature and long-blooming habit. After planting Angelonia, you should research the ideal growing circumstances.



First of all, plant your Angelonia in full sun to give it the energy it needs to keep blooming. Plants that do not receive at least six hours of direct sunlight become leggy and produce few flowers.


Angelonia plants tolerate a wide range of soil requirements, but prefer a pH range of 5.5 to 6.2. Organic matter-rich soil requires less watering and fertilizer. Because plants need good drainage to avoid root rot, try growing Angelonia in raised beds or containers if you have heavy clay soil.


Angelonia plants are tough and will bloom even if there is a drought. When the top of the soil seems dry, water it. If the plants have good drainage, adding moisture is fine. Regular, thorough watering is important for the health and well-being of your plants. Long, thorough soakings of the soil are more efficient than watering it regularly and lightly.


The ideal temperature is 62-65 degrees Fahrenheit at night and 65 degrees Fahrenheit during the day. It is not difficult for good-quality growth to allow day temperatures to reach 85-95 degrees Fahrenheit. Warm temperatures are ideal for Angelonia. However, temperatures that are too chilly will inhibit growth and delay flowering, extending the entire crop time.


Summer temperatures and excessive humidity are ideal for Angelonia plants.


Angelonia plants are light feeders, and too much fertilizer will cause an overgrowth of foliage at the expense of blossoms. Fertilize them regularly. At planting time, you can also use a balanced floral fertilizer with a timed-release mix of a 10-5-10 or 12-12-12 fertilizer.

By means of basing on conditions, Angelonia will develop and bloom, making a vibrant addition to the garden. 

How to take care of Angelonia?

Another point worth noting is how to care for Angelonia. Keep reading to find out more tips for taking care of them. Planting Angelonia and taking care of it are very necessary stages for the development process. 

Angelonia care after they start growing

Some believe that as Angelonia begins to grow, you should concentrate your efforts on providing better circumstances and nutrients for its development.

During the Angelonia growing season, you should keep weeds under control. Weeds compete with plants for water, space, and nutrients, so keep them under control by cultivating frequently or mulching to keep their seeds from developing.

After new growth occurs, a light fertilizer can be applied. To avoid burn harm, keep granular fertilizers away from the plant’s crown and foliage. Slow-release fertilizers should be applied at modest rates, as greater rates may induce root rot.

Moreover, you have to keep the soil moist but not soggy. They can endure slightly drier conditions after their roots have grown. Angelonia plants should not be allowed to dry out to the point of wilting. This will turn the bottom leaves yellow and sap the plant’s energy.

This part is for you if you’re concerned about how to care for the Angelonia after it blooms. It includes the best suggestions and advice for caring for this plant and ensuring that it blooms for a longer period of time.

The blooms bloom for a long time in the summer, lasting 4-6 weeks in temperate climes and much longer in zones 8-11; in North Texas, the blooming season is from May to October.

The blooming stage has ended, and the seed disbursing stage has begun. The flower’s life cycle has come to an end. Now is the time to cut and remove the purple-blue dried flower clusters. Just make sure they’re completely dry before removing them.

Either exactly beneath or slightly below the dead and dry flower clusters. You don’t have to cut directly under the dead flower; in fact, you can reduce your Angelonia back to half its original size.

Collecting Angelonia seed

Saving seeds from non-hybrid Angelonia ensures that these heirloom plants will be passed down through the generations. Collecting and storing Angelonia seeds is an excellent way to enrich your garden from year to year.  

There are 4 steps to collect Angelonia seeds:

Harvesting the Seeds

Wait until the blossoms have totally faded in color. You can see the seed casing Wait until the seedpod gets a light tan color. Because the seed pod is small, at around 14 inches in diameter, you’ll have to search closely to discover it.

Before picking the seeds off the plant, wait until they are fully grown. The best time to harvest the seeds is usually September or October. Moreover, the seed on the top of the Angelonia plant differs from the seed on the bottom. Save the seed heads near the bottom of the plant.

Remove the last few petals and look for the seed capsule. You should remove the light tan pods from the stalk. The pods are right beneath the blooms’ attachment points.

In a small basin, place the pods. To reveal the seeds inside, slit them open with the tip of a knife. Angelonia seeds are quite small.

Simply snap the plant’s seed head off and set it in a bowl.

Catching Seeds in a Bag

Take a plastic bag and secure it around the flower pod with a twist tie. If the pod opens before you can pick it off the plant, the seeds will fall into the bag rather than on the ground.

Removing the Seeds

Now comes the difficult part: removing the seeds. Cover the bottom of a tray with white paper. This will make the seeds stand out more when they emerge.

Then you should use tweezers to remove any fuzz from the seed bowl that has come out of the pod.

What is more, Fill a strainer halfway with the seeds. The seed will fit through the strainer, but everything else will get caught. You will not have to sort through your seeds later if you do this step.


Fill a tiny vial or plastic bag with your seeds and seal it shut. Label the seed with the flower’s color, the place where it was grown, the quantity of sun it needs, and any other information you’ll need for next year’s planting.

Over the winter, store the packet in a cool, dry location. You can take them out and replant them in the spring.


Place a packet of silica gel in the envelope if moisture is an issue. Florists can provide you with silica gel.

Seeds decay when they are exposed to moisture. Always keep them in a dry location.

How to propagate Angelonia?

You can propagate Angelonia from seed, cuttings and division. You can find further information about how to propagate these flowers here. 


  • The seeds are small and can be picked in late summer from seed pods, dried, and preserved until the following spring.
  • Sow seed six to 12 weeks before the last predicted spring frost indoors at 70 to 75 degrees Fahrenheit in well-drained soil with a pH of 5.5 to 6.0.
  • There’s a chance that when you propagate seeds from an existing plant, the plant won’t grow exactly like its mother plant.


Angelonia stem cuttings are easy to propagate:

  • Step 1: Take a 3-inch clipping from the tip of an Angelonia stem with a sharp knife. Select a cutting that is devoid of flowers.
