Alonia Violet, also known as Summer Snapdragon, is an annual landscape flower native to Mexico and the West Indies. The Alonia series of Angelonia Angustifolia developed by Danziger offers superior habit, growth in the garden, and early blooming compared to native plants. Alonia Violet has an upright mounding habit 10-14" tall and 12-14" wide. It continues to grow in the garden, where tall violet flower spikes bloom from spring through fall. It is rabbit and deer resistant but attracts pollinators. This plant is heat tolerant and flourishes in full sun or partial shade in patio containers, landscape borders, and rock gardens. Customers will also enjoy it as a cut flower indoors. Pair Angelonia with Calibrachoa, Dahlia, and Geranium to create an attractive mixed container or modern cottage garden. For a larger variety, try Big Grape.
Alonia Violet Selling Tips
Sell Angelonia Alonia to customers looking for attractive sun-loving flowers for containers and landscape borders. This plant has many benefits to offer your customers. It is heat tolerant, rabbit and deer resistant, and attracts butterflies and hummingbirds. Tall spikes with violet flowers start in early spring and bloom continuously through fall. Angelonia flourishes in full or partial sun with moderately moist soil and some drought tolerance. Customers will love the showy flowers and compact upright habit for mixed containers and landscape borders. Plant Alonia Violet with Alonia Pink Flirt and Alonia Snow Ball for a stunning show of color and texture in a small landscape border.
Coach Your Customer
1. Space plants 12-14 inches apart in well-drained moist soil in full or partial sun. Water regularly.
2. Feed plants every few weeks from spring to fall, during the blooming season. Deadhead spent flower spikes to promote continuous blooming. Remove plants in the fall.
General Growing Tips For Your Rooted Cutting Liner
For best results with Alonia Violet, grow one rooted plug per 4-inch, 5-inch, or gallon container. Use well-drained soil with a pH of 5.8-6.2, EC of 1.0-1.2 mS/cm, and light feed (100-150 ppm N). Pinch once at transplant and apply a fungicide after transplant. Provide average daily temperatures of 65-68 degrees. Extended day or night interruption lighting isn't required but may be beneficial. Use a spray of daminozide at 2,500-3,750 ppm and a paclobutrazol drench at 1-2 ppm if needed. Watch for aphids, thrips, botrytis, pythium, and phytophthora.
Flowering
Violet flower spikes bloom from spring through fall.
Pinching
Pinch once at transplant.
Spacing
Grow Angelonia pot tight in 1801s, 4-inch, or gallon containers. Space them as they reach their final size to keep foliage from touching.
Height Control
Angelonia responds to a daminozide spray of 2,500-3,750 ppm or a paclobutrazol drench at 1-2 ppm as needed during finishing. Control height with proper cultural controls first, especially by allowing the soil to dry slightly between waterings and maintaining low fertilizer levels.
Pests
Scout for aphids and thrips as part of your Integrated Pest Management (IPM) program.
Aphids are small, soft-bodied insects that cause damage by sucking sap from plant tissue. They reproduce quickly and are particularly attracted to young growth. Curling and yellowed leaves, stunted growth, and stickiness on leaves are signs of an infestation. These insects also spread diseases and reproduce rapidly. Use biological controls or horticultural oils to discourage and kill aphids.
Thrips are tiny insects that eat plant tissue and can transmit viruses. Watch for silvery-white streaks or black spots on foliage and distorted growth. Use natural predators (like predatory mites), insecticidal soap, neem oil, and sticky traps to control infestations and prevent spread.
Disease
Scout for Botrytis and Root Rot as part of your greenhouse's IPM program. Take preventative measures against disease by watering at the base of each plant, allowing plants to dry between waterings, spacing containers to allow for adequate airflow and sunlight penetration to the base of each plant, and providing good airflow in the greenhouse.
Botrytis is a common fungal disease that causes brown spots on stems, leaves, and flowers. Remove and destroy affected plants, maintain appropriate humidity levels, and apply fungicides with boscalid, fenhexamid, or iprodione to control the spread. Water plants in the morning and allow the soil to dry slightly between waterings.
Root Rot occurs in poorly drained or overly wet soil, which becomes the host for several types of fungi. It causes stunted growth, wilting, and root system decay. Prevention is the best treatment, and you will avoid most root rot problems by using clean, well-draining media, appropriate containers, and good watering practices for finishing seedling plugs. Inspect plants for signs of disease regularly. Repot infected plants in well-draining soil, adjust your watering schedule, provide better airflow, and use a fungicide if needed.
Planting Alonia Violet Liners
We recommend planting one rooted plug per 4-inch, 5-inch, or gallon container. Use well-drained soil and center the plug in the container.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
