Size and Growth

Aloysia virgata is an upright to rounded shrub/tree, reaching up to 15′ feet tall in height and spreading up to 12′ feet in width. 

The plant usually has evergreen leaves in warmer climates while it grows as a deciduous plant in cooler regions. 

In subtropical climates, the plant swanks semi-evergreen leaves.

These versatile leaves are usually oval in shape with a smooth surface and a grayish-green color. 

They expand to 4″ inches long and half as wide. 

Flowering and Fragrance

Sweet almond bushes develop long, pointy spiked flower clusters with pretty white blooms. 

These flowers are supremely fragrant and fill the garden with a sweet scent of vanilla or almonds. 

Sweet almond flowers have an extensive bloom period. 

They stay abloom all summer long and well into fall.

Lighting and Temperature

A sweet almond bush enjoys full sun and part shade. 

It mostly requires five hours of sun a day. 

The sweet flowering almond tree does best in a variety of climates. 

However, it necessitates a brief period of chilly weather to kick-start flowering in the spring season.

The minimum cold temperature for the growth of sweet almond trees is from 10° to 15° degrees Fahrenheit (-12° to -9° degrees Celsius).

The large shrub falls in the USDA hardiness zone 7.

Watering and Feeding

Sweet almond bushes are drought-tolerant. They easily thrive in hot climates and won’t need regular watering. 

However, this deciduous shrub requires little water to keep growing happy and healthy. 

Ideally, water the bush twice a month, especially during the dry weather conditions.

When it comes to feeding, botanists suggest using a general landscape fertilizer (10-10-10) for the plant. 

Apply it once in March, June, and August to encourage healthy growth. 

An alternative to a general landscape fertilizer is a slow-release fertilizer.

Soil and Transplanting

The shrub performs best in an extensive range of soils from loamy soil to clay. 

During the first year of the plant, water it regularly to keep the soil wet. 

This will help the plant to develop a strong and healthy root system.

Transplanting of established shrub shocks the plant which is why it is seldom recommended. 

However, it may be necessary if a landscape is not ideal for the shrub’s growth. 

Before transplantation, water the soil to soak it well. 

This lets you dig up the shrub easily. 

Next, dig up a wide hole to house the root ball. 

Using burlap, place the root ball in the newly-dug hole. 

Make sure to place the plant in a sunny spot so it gets enough sunlight. 

Gently firm the soil and water it regularly.

Grooming and Maintenance

Unlike high-maintenance shrubs, sweet almonds do not need deadheading. 

Pruning this flowering shrub should be an annual affair. 

The plant bursts with beautiful flowers in early spring and tend to multiply in numbers over the seasons.

Hard pruning is often done to keep the plant full and compact. 

Pruning should take place right after the bloom time is over i.e., late summers. 

Avoid pruning in winter as this may cut off next year’s buds. 

Always ensure the plant is receiving enough sunlight to grow.

  • Trim them and then place them in a plastic bag. 
  • Keep them in the shade until the roots grow.
