Why Gardeners Love Mona Lavender
'Mona Lavender' has become increasingly popular because it combines beautiful flowers with attractive foliage throughout the year. Even when it isn't blooming, its rich green leaves and purple undersides create a striking contrast.
Unlike many flowering ornamentals, it tolerates shade exceptionally well. This makes it an excellent choice for patios, covered porches, balconies, woodland gardens, and indoor spaces with bright indirect light.
The plant also attracts bees, butterflies, and other beneficial pollinators while requiring relatively little maintenance.
Choosing the Best Location
Location plays a major role in the long-term health of your plant.
'Mona Lavender' performs best where it receives bright filtered light or morning sunshine followed by afternoon shade. Too much direct afternoon sunlight may scorch the leaves, while excessive shade can reduce flowering.
Ideal growing locations include:
Covered patios
Shaded balconies
East-facing gardens
Bright indoor windows
Under taller shrubs or trees
Good air circulation also helps reduce disease problems.
Sunlight Requirements
One of the biggest advantages of 'Mona Lavender' is its adaptability to lower light conditions.
The plant prefers:
Bright indirect sunlight
Partial shade
Morning sun with afternoon protection
Avoid exposing the plant to harsh midday summer sun for long periods, especially in hot climates.
Plants receiving the proper amount of light generally produce more flowers and richer foliage color.
Best Soil for Mona Lavender
Healthy soil provides the foundation for vigorous growth.
'Mona Lavender' prefers loose, fertile, well-draining soil rich in organic matter.
An excellent soil mix includes:
Quality potting soil
Compost
Coco coir
Perlite
Pine bark fines
The soil should remain slightly moist but never soggy.
Heavy clay soils should be improved with organic matter before planting.
Planting Mona Lavender
Whether planting in the ground or containers, preparation is important.
Choose a container with drainage holes if growing in pots.
Fill the container with fresh, well-draining potting mix.
Plant at the same depth as it was growing in the nursery container.
Water thoroughly after planting to settle the soil around the roots.
Avoid burying the crown too deeply.
Watering Guide
Proper watering is one of the most important aspects of care.
'Mona Lavender' enjoys evenly moist soil but dislikes standing water.
Allow the top inch of soil to dry slightly before watering again.
During hot summer weather, watering may be needed more frequently.
In cooler months, reduce watering to prevent root problems.
Overwatering is far more dangerous than slight underwatering.
Fertilizing for Healthy Growth
Regular feeding encourages lush foliage and abundant flowers.
Apply a balanced water-soluble fertilizer every four to six weeks during spring and summer.
Organic options include:
Compost
Vermicompost
Fish emulsion
Seaweed fertilizer
Avoid excessive nitrogen, which may encourage leafy growth at the expense of flowers.
How to Encourage More Flowers
Flower production depends on proper care.
Provide:
Bright filtered light
Consistent watering
Balanced fertilizer
Regular pruning
Removing spent flower spikes encourages continued blooming and improves the plant's appearance.
Healthy plants may bloom for several months.
Pruning and Maintenance
Pruning helps maintain a compact, bushy shape.
Pinch growing tips regularly during the growing season to encourage branching.
Remove:
Dead flowers
Yellow leaves
Weak stems
Damaged growth
Annual pruning after flowering keeps the plant attractive and vigorous.
Propagating Mona Lavender
Propagation is simple and rewarding.
Stem cuttings root quickly in water or moist potting mix.
Choose healthy non-flowering stems approximately four to six inches long.
Remove lower leaves before placing the cutting into rooting medium.
Keep warm and lightly moist until roots develop.
Many gardeners produce multiple new plants each year using this method.
