Angelonia Plant Care

Updated February 21, 2017

Angelonia plants can add colour and texture to a flower bed for the summer. They grow well in zones 10 and 11. When planting angelonia plants, it is important to estimate their full-grown height when planning the flower bed. Angelonia plants can grow up to 2 feet tall. This makes them a good backdrop for a flower bed or a centre focal point. Angelonia are resilient plants that are easy to care for and are good for beginning gardeners.


Angelonia plants will grow the best in full sun. When selecting a location in the flower bed or landscaping, take care not to plant them where they will be overshadowed by other plants. The soil should be able to drain well. If planted too early, cold temperatures can delay or limit the growth of angelonia plants.


Angelonia plants can handle drought well and should be watered regularly. However, it is important not to allow water to collect around their roots. Too much water can cause damage to the roots. They can handle drought well and should not suffer if a watering is missed.


Fertilisation isn't necessary for angelonia plants to grow well. However, if the soil is lacking in nutrients, it may be beneficial. However, fertiliser should be applied after flowers have been harvested. The extra nutrients from the fertiliser will help the plant to start new shoots for new flowers. Using too much fertiliser can damage angelonia plants, so fertiliser should be applied only on occasion.


The blooms of an angelonia plant come in a variety of colours. They look like snapdragon blooms and can be harvested for bouquets. Angelonia plants are self cleaning and do not require deadheading to continue to bloom and look good. The blooms and foliage are fragrant and can provide a pleasant scent to a bouquet.


Angelonia plants don't have many pests to deal with most of the time. However, large numbers of aphids, whiteflies or thrips can become a problem. Rarely do large enough numbers of these pests congregate to cause a real threat to angelonia plants. Pesticides can be used to aid the plant if any of the pests become a big problem.
