Mona lavender

Growing in Pots, Balconies & Indoors

Mona lavender is one of the easiest of this group to grow indoors – the grower marks it as a genuine houseplant, and it also thrives in patio and balcony containers. At 40-80 cm (16-32 in) and happy in half to full shade, it suits a bright room, a shaded balcony or a mixed pot.

Quick Details

• Container Size: A medium pot, roughly 3-7 L (1-2 gal), potting up as it fills
• Indoor Suitability: A good houseplant in bright, indirect light
• Best Spot: Bright indirect light indoors; half to full shade outdoors
• Soil & Drainage: Aerated, organic-rich mix that drains freely
• Watering in Pots: Keep lightly moist – pots dry faster than open ground; never waterlogged

Indoors & On the Windowsill

• A real houseplant: Grow it in a bright room out of harsh midday sun. It flowers well in good indirect light and is forgiving of normal indoor conditions.
• Windowsill: An east- or north-facing sill with bright, filtered light is ideal; keep it off scorching glass.
• Overwintering: Being tender, it is easily kept as a potted plant indoors over a cold winter and returned outside once mild.

On a Balcony or Patio

• Light & shelter: It prefers a shaded or part-shaded balcony out of the strongest sun and wind. Reflected heat from walls dries pots fast, so check moisture in warm weather.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A pot with strong drainage holes; skip a standing-water saucer to avoid root rot. Terracotta breathes and dries faster, glazed or plastic holds moisture longer.
• Potting mix: A well-aerated, organic-rich mix – peat or coir with perlite or vermiculite.
• Feeding: Feed regularly in growth, as potted plants leach nutrients faster than ground plants; pinch tips to keep it bushy.
• Repotting: Refresh the mix or pot up about every couple of years; it is easily renewed from cuttings.

Bloom & Flower Guide

Quick Details

• Bloom Season: Almost all year, with the heaviest flush as the days shorten in autumn and winter
• Flower Appearance: Small lavender-purple flowers, often with fine darker spotting, held in upright spikes above the foliage
• Edibility: Ornamental only — grown for its foliage and long flowering, not for eating

Detailed Blooming Overview

Mona Lavender is a floriferous Plectranthus hybrid that flowers over a very long season. It is a short-day plant, so its strongest show comes as daylight shortens through autumn and winter, when upright spikes of soft lavender flowers rise above the dark, purple-backed leaves. The blooms are a useful late nectar source for pollinators.

Flower Characteristics

• Small, tubular lavender-purple flowers, frequently freckled with darker spots.
• Carried in slender upright spikes that stand clear of the foliage.

Bloom Care & Thinning

• Encouraging bloom: Bright light and shortening days trigger the main flush; avoid strong artificial light at night, which can delay flowering.
• Prolonging the display: Pinch young plants to build bushiness and deadhead spent spikes to keep fresh flowers coming.
• Pollination: The spikes attract bees and other pollinators.
