Mackaya bella

DESCRIPTION

Asystasia bella (formally Mackaya bella) is an attractive, semi-hardy, evergreen shrub which thrives in deep shade conditions. The glossy dark-green leaves have a prominent midrib and veins on the lower surface. The margins are wavy and widely toothed.. Masses of white or light lavender flowers with prominent burgundy veins are borne from spring to mid-summer.

NATURAL HABITAT & DISTRIBUTION
Forest understorey.
WILDLIFE & ECOLOGICAL BENEFITS
Asystasia bella is a larval host plant to the Blue Pansy butterfly.
WATER REQUIREMENTS
Water moderately throughout the year.
MAINTENANCE
Asystasia bella is low maintenance and will grow to a neat shrub up to 4 metres tall.
Prune back after flowering to encourage dense growth and a non-woody plant.
LANDSCAPING USES
A superb shrub for an informal hedge in a shady area. Ideal for small gardens.
It may also be grown in a large pot in a shady courtyard.
Ideal companion plants are Clivia miniata, Asparagus densiflorus and Plectranthus verticillatus.
GARDEN THEMES
Forest, Formal, Rockery, Tropical, Woodland
FLOWERS
White or lavender, bell-shaped flowers, each comprising a tube ending in 5 spreading lobes and streaked with purple veins.
FOLIAGE
The glossy dark-green leaves have a prominent midrib and veins on the lower surface.
FRUIT
The fruit is a green, club-shaped capsule that matures to brown then explodes into two to eject the seeds.
SEED
BUTTERFLY/MOTH HOST PLANT
Junonia oenone (Blue Pansy)
PESTS & DISEASES
Seldom attacked by pests and diseases.
CULTIVATION
Asystasia bella is easily propogated by semi-hardwood cuttings taken in autumn or spring or from seeds sown in spring. It performs best in heavily composted, well-drained granitic soil and needs regular watering in summer for the first year until well established. Feed with a slow-release 3:1:5 fertilizer every two months in summer. The plant responds well to a light pruning after flowering to encourage bushy new growth and to maintain a compact shape.

  1. Hi Anthon

    Thanks for visiting Plantbook.

    The life expectancy of plants depends to a large extent on the growing conditions.

    We have seen some garden specimens at are at least 20 years old and they are still thriving.

    Thanks for visiting Plantbook.

    It is always tricky planting under an established tree.

    Without trying to dissuade your plant selection, realise that Asystasia bella may not thrive under your Cedrus deodara (deodar tree) for the following reasons:-

    1. Fallen needles from Cedrus deodara (deodar tree) tend to make the soil very acidic which makes it difficult to grow most plants around them.
    2. There may be competition with the tree for nutrients and water.

    Although not indigenous, you may also wish to consider hydrangeas, camellias or azaleas under your tree as these definitely thrive in acidic conditions.

  3. Hi Gillian

    Thanks for visiting Plantbook.

    Shrivelled leaves can have a number of causes. Without knowing any details about your watering and feeding regime, I’ll have to give you general pointers to consider:

    – Watering should rather be for a long duration, to ensure that the water penetrates deeper into the ground to reach the roots.
    – Avoid over-watering which can also stress the plant and cause withered leaves. An established Mackaya can survive with minimal watering, but this will depend on your soil and garden’s micro-climate.
    – Could your water be contaminated?
    – Mackaya thrives in a forest environment, so ensure that your planting area is rich in compost and leaf litter.
    – As with most plants, feeding should only take place when there is active growth and flower production. Over-feeding can cause the leaves to wither.
    – Use an organic fertiliser
    – Could there have been an accidental chemical spillage near your plant?
    – Is there any insect activity on the plant?
    – What is the age of the plant? It could perhaps be reaching the end of its life.

    I hope this helps.

  4. My mackaya bella is not looking very healthy with shrivelled and withered leaves despite feeding and watering. What can be causing this? I live in the Cape, South Africa.

  5. Hi Francois

    Thanks for visiting Plantbook.

    It depends on where you’re looking and what size you require.
    A 4l plant will cost around R50 and a 40l plant will be roughly R500.

  7. Please can you let me know if is possible to buy this plant ( Mackaya Bella) in the uk ?
    If so where.

    Thank you

  8. Hi Elma

    Thanks for visiting Plantbook.
    Mackaya bella is a forest species that prefers full shade. However, I’ve seen some planted in full sun and they’ve adapted.

    If you don’t have the shade, consider planting it on the south east side of your home which may only receive morning sun in summer.

  9. Thank you for the relevant info. Would be ideal during winter but the summer sun would be too harsh unfortunately
