Because snapdragons are annuals that thrive in chilly weather, their allure in a garden is powerful but short-lived. This is because their beauty soon wanes as the summer heat sets in. On the other hand, Angelonia, also known as Angelonia Angustifolia, is a counterpart ready to stand firm long after the last snapdragon has withered.

Angelonia is treated as a perennial in USDA cold hardiness zones nine and above, even though it is planted as an annual in more temperate regions. At the very tops of sturdy stems covered in slender green leaves, racemes of white, pink, mauve, violet, or purple blooms resembling orchids bloom in clusters. Other color options include violet and mauve. Angelonia is a bonus plant since it has a sweet aroma, especially on warm summer evenings.

Angelonia Care Instructions


Angelonia's hardiness and extended blooming time make it an indispensable component of summer flower beds and container gardens. Pollinators are drawn to the park thanks to the fragrant flowers and abundant nectar they produce. These low-maintenance plants do not need to remove their spent blossoms, and they will continue to provide you with blooms for some weeks.


If you want your Angelonia to bloom continually, you should plant it where it will get enough sunlight. Plants that do not get at least six to eight hours of direct sunshine each day will have less flower production, grow taller, and have more lanky stems.


Angelonia may grow in a broad range of soil types, although it does best in conditions with a pH between 5.5 and 6.2. A lower need for watering and fertilizing will result from having soil rich in organic matter. To avoid developing root rot, plants require soil with enough drainage. Consider growing Angelonia in a raised bed or container if the garden soil is heavy clay; alternatively, consider enriching the soil to enhance the tilth of the ground.

Water Requirements


Angelonia is exceptionally drought-resistant and will maintain its beautiful blooms even in the driest of conditions. Water the plant when the top few inches of the soil feel dry. If the plants have enough drainage, adding more moisture is not necessary.

Temperature And Relative Humidity

Angelonia is most successful when grown in high temperatures and high humidity conditions. They do best in the region's hot and humid climate, typical of the deep South, and Angelonia does well in the Southwest if it receives a little bit more water.


Because angelonia plants are light feeders, you should fertilize them monthly. An excessive amount of fertilizer can result in an overgrowth of foliage, preventing blossoms from developing. When planting, you may give your plants a small amount of flower fertilizer, preventing you from applying more fertilizer later. Follow the directions on the product label for the amount that should use.

Pruning Process


Angelonia is one of the few annuals that may continue to bloom without having its spent flowers removed. The plants should be pinched when they are still young to get a bushier appearance.

Propagating Steps

  • Stem cuttings are an effective method for the propagation of Angelonia.
  • Take a cutting of the tip of an angelonia stem that is around three inches long, utilizing a sharp knife. Pick a cutting that does not include any blooms.
  • Remove all leaves from the cutting, except for the top pair, because the stem cannot sustain the weight of other leaves without a root system.
  • Put some soilless potting mix in the bottom of a small container. Create a little hole in the ground using a pencil or your finger.
  • After dipping the cut end in rooting hormone, put it into the potting soil that has been kept moist.
  • Keep the soil wet at all times.
  • When it begins to produce new leaves, you will know that it is ready to be transplanted into your garden.

Growing From Seeds

Growing From Seeds

Because angelonia seeds are extraordinarily minute and difficult to handle, it is recommended that you purchase pelleted seeds instead. This makes the seeds significantly bigger and covers them in a lump of clay that decomposes once planted.

It would be best to start Angelonia seeds indoors approximately six weeks before the latest frost date. They should press Them into sterile potting soil but not cover bases themselves; exposure to light is necessary for germination. Intense sunlight should provide adequate moisture to the seeds with a temperature of between 70 and 75 degrees Fahrenheit. The germination process might take anything from one to three weeks. In the garden, leave a distance of eight inches between each seedling.

Planting And Replanting In Pots

Angelonia plants are ideally suited to grow pots due to their neat, self-cleaning nature and tendency to bloom continuously. By placing some angelonia in a pool or patio pot, you can take advantage of the plant's appeal to hummingbirds and butterflies. Large containers with a diameter of at least 18 inches won't lose their moisture content as quickly as smaller ones.

You should report your angelonia plants when the evening temps begin to warm up in late April. Make use of commercial potting soil, which will provide adequate drainage and acidity levels for your plants. Angelonia has a shallow root system and does not require repotting because of its compact nature when cultivated as an annual. In the spring, repotting overwintered plants will help rejuvenate the growth medium.



Angelonia is often planted annually in colder areas; however, it is possible to overwinter container plants inside during winter. You should bring it inside when the temperature drops below 60 degrees Fahrenheit throughout the night. Please put it in a location next to a window where it will get plenty of strong, direct light, and the temperature in the room will remain relatively stable at approximately 65 degrees Fahrenheit. To maintain the soil's moisture level, rinse it around once each week. Move the plant outside after springtime. Low evening temperatures reach a range that is at least lower than sixty degrees Fahrenheit.

Pests That Are Usually Seen

Angelonia often has issues with aphids, particularly at the beginning of the growing season when the plants are going through a period of fast expansion. If you give your plants a small sprinkling of insecticidal soap twice a week, you may eliminate pests before they have a chance to cause damage to your vegetation.
