Hi @d23,
With any of these suggestions, mainly due to the limited space in relation to the pavers, I would suggest installing a Root Barrier around these trees. When planting, dig down around 500mm and 1000mm in diameter to install the barrier. Once in place, backfill with the soil and plant your trees. This barrier will help direct the root growth down before it moves laterally, which will help protect your pavers.
In terms of trees you could use, here are some suggestions -
Crepe Myrtle (Lagerstroemia indica) dwarf varieties such as Acoma or Indian Summer, which grow to about 3–5 metres, will provide vibrant summer blooms in pink, purple, red, or white, beautiful autumn foliage, and attractive bark.
Magnolia ‘Kay Parris’ (Magnolia grandiflora) are evergreen with glossy foliage and fragrant white blooms, and they have shallow, non-aggressive roots—ideal for formal settings.
Japanese Maple (Acer palmatum) provides stunning red or orange autumn colour and delicate foliage. Upright varieties reach 3–4 metres and have roots that won’t disturb nearby paving.
Frangipani (Plumeria rubra) offers a tropical feel with fragrant flowers in white, yellow, or pink, and grows slowly to around 5 metres. Its roots are non-invasive, making it ideal near foundations or pavers.
Allow me to tag some of our experienced gardeners such as @mich1972, @robchin and @mashthyme, to see if they have any preferences or recommendations.
Let me know what you think and if you have any further questions, please don't hesitate to ask.
Jacob
