About Magnolia grandiflora 'Kay Parris'

Magnolia grandiflora 'Kay Parris' is an evergreen Southern Magnolia selection with narrow, wavy edged leaves that are glossy dark green above and coated in rich rusty brown felt beneath. Large, fragrant, creamy white flowers appear from summer into early autumn. Smooth grey bark and foliage held low on the trunk complete the picture.

It grows in full sun to partial shade in well drained, slightly acidic soil, and tolerates a range of soil types. Warm temperate, temperate and subtropical districts suit it, and it is drought tolerant and largely free of pest and disease problems once established. Growth is slow to moderate at 20 to 40 centimetres a year.

This is a compact tree at maturity, 4 to 6 metres tall and 2 to 3 metres wide, so it fits a courtyard, a school ground, a rural entry or a suburban garden. Younger plants screen well while they fill out. Buyers get a long lived evergreen with year round structure.

Frequently Asked Questions

About Kay Parris Magnolia

What is Magnolia grandiflora 'Kay Parris'?

It is an evergreen cultivar of the Southern Magnolia with narrow, wavy edged leaves that are glossy dark green above and covered in rusty brown felt beneath. Large, fragrant, creamy white flowers open from summer into early autumn. Smooth grey bark and dense foliage low on the trunk give it presence year round.

How big does Kay Parris grow?

At maturity it reaches 4 to 6 metres in height and 2 to 3 metres in width, so it is a compact tree and easy to site. Reaching that size takes decades at its slow to moderate rate. Allow at least 3 metres from buildings, boundaries and underground services.

When does it flower?

From summer into early autumn, roughly December through to March, with flowers appearing in flushes rather than all at once. The blooms are large, creamy white and strongly perfumed, particularly in the evening. Young plants often flower within a few years of planting, which is earlier than the parent species manages.

Is it drought tolerant?

Yes, once established it handles dry periods well and is one of the more resilient evergreen shade trees for temperate and subtropical Australia. It also resists most pests and diseases. Young trees still need consistent water through their first two or three summers while the root system reaches subsoil moisture.

Does it have invasive roots?

The roots are fleshy and mostly shallow rather than aggressively invasive, and the root plate stays in proportion to the compact crown. Keep it clear of paving, tanks and drainage lines, and expect some surface rooting under the canopy in time. Given its modest final size it suits courtyards and narrower garden beds.

How fast does it grow?

Slow to moderate, about 20 to 40 centimetres a year. Growth is quickest in warm, humid districts with good soil and slowest in cold or compacted ground. Because it is not a fast tree, starting with an advanced specimen makes a real difference to how soon the planting reads as established.

How do I care for Kay Parris Magnolia?

Plant into well drained, slightly acidic soil, water deeply through the first summers and mulch out to the drip line. Feed in early spring with a fertiliser for acid loving plants. Pruning is optional, limited to lifting the lower skirt if you want clearance underneath. Do that after flowering and keep the cuts small.

Watering: Water deeply twice weekly through the first 12 months. Once established, keep the root zone consistently moist with weekly deep watering and additional water during hot dry spells.

Mulching: Apply a 5 to 7 centimetre layer of organic mulch over the root zone, keeping it 5 centimetres clear of the trunk.

Pruning: Tip prune in late winter and again in summer to build dense growth. For a formal hedge, light shaping two to three times a year keeps lines crisp.

Fertilising: Apply a slow-release general-purpose fertiliser in early spring and again in autumn for steady growth and consistent foliage colour.

Pest and disease: Hardy against most pests and diseases. Occasional inspection in warm humid conditions is all that's needed.

Planting Your Magnolia grandiflora 'Kay Parris' in Different Soil

Magnolia grandiflora performs best in rich, well-drained loam with a slightly acidic pH and consistent moisture. Adaptable to a wide range of soils when drainage and organic matter are managed well.

Sandy soil: Free-draining but enrich heavily with compost and mulch deeply to hold moisture.

Clay soil: Improve drainage with gypsum and organic compost, and mound slightly to lift the root zone.

Loam: The preferred soil for steady root development and consistent flowering.

pH: Slightly acidic preferred. Mulch with composted leaf litter or pine bark to maintain levels naturally.

Plant Your Magnolia grandiflora 'Kay Parris' With:

Enriched Planting Mix (AO Certified)

Enriched Planting Mix is a certified organic blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent, bagged in 30L. It is built to be dug through existing garden soil at planting time rather than used on its own, and the gypsum is what sets it apart from a plain compost.

Gypsum helps break up heavy clay so water and roots can move through it, while the compost and manure return organic matter and nutrient to tired ground. The coarse bark holds structure and keeps air around the root zone, and the wetting agent keeps moisture in the soil longer after rain or watering.

Use it when planting trees, shrubs, roses, fruit trees and exotic garden plants, particularly into clay. Dig a hole twice the width of the pot and 7 centimetres deeper, then mix roughly one third planting mix through the excavated soil. Spread 7 centimetres of that improved soil in the base before setting the plant in.

Frequently Asked Questions

About Enriched Planting Mix

What is Enriched Planting Mix made from?

It is a blend of Pure Magic Compost, composted animal manure, gypsum, composted coarse bark and a wetting agent. Each part has a job. The compost and manure supply organic matter and nutrient, the gypsum works on clay structure, the bark keeps air around the roots and the wetting agent holds moisture in the soil.

What plants is it suitable for?

It suits exotic garden plants, including roses, ornamental and deciduous trees, fruit trees, shrubs and perennials, and it earns its keep most on heavy clay sites. It is a planting mix rather than a potting mix, so its job is improving soil at planting time. Phosphorus sensitive natives are the one clear exception.

Is it safe for natives?

No, not for the phosphorus sensitive ones. The composted animal manure in this blend lifts phosphorus well above what Proteaceae such as Banksia, Grevillea, Hakea and Protea will tolerate, and the result can be leaf burn, dieback and plant death. Use the Native Potting Mix for those species, or plant them into unimproved local soil.

Is it certified organic?

Yes. It is a certified organic product with no chemical additives, which is why the manure and compost in it are fully composted rather than raw. That makes it sound around fruit trees and vegetable beds, and it means you are adding genuine organic matter to your soil rather than a synthetic conditioner.

How much do I need?

Work on roughly one third planting mix to two thirds of the soil you dug out of the hole. For a shrub out of a 200 millimetre pot that is only a few litres. An advanced tree going into a large hole will take considerably more. Judge the quantity by the volume of the hole rather than the size of the plant.

Can I use it in pots?

It is not a potting mix and should not be used on its own in a container. The blend is designed to be diluted through garden soil, and used straight in a pot it holds too much water and settles badly. For containers, reach for a premium potting mix, or the native mix if you are potting natives.

Does it need to be watered in?

Yes. Water the plant well several hours before you plant it, then water thoroughly again once the hole is backfilled and the soil firmed down. That first deep watering settles the improved soil around the root ball and drives out air pockets. Keep the water up over the first few months while the roots establish.
