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.
