As the season is well advanced now it is satisfying to see good growth on plants which were potted-on into generous sized Air-Pot containers earlier this year. Two plants I wanted for their striking foliage are well on the way to becoming dramatic specimens. An Agave filamentosa has formed a neat rosette of variegated spears and a Phormium is developing an interesting stripy bronze fan, both of these will be exciting shapes and colours to have around the garden, especially in winter when there is little leafiness or colour.

A little collection of potted Canna Lily have all thrown up dense thickets of stems; moving them into bigger pots has resulted in vigorous multiplying shoots and lots of blooms. Usually Canna are grown from rhizomes, but a few seed saved last year and sown in February have formed many shoots and surprisingly have flowered after just a few months.

A young olive tree started in a 1 litre Air-Pot has doubled in size since being moved into a 3 litre earlier this year and has a good sturdy shape with dark green healthy looking leaves. Another much older olive tree recently moved into an Extra-Large 38 litre Air-Pot has produced a huge number of flowers for a container grown tree. This veteran plant seems determined to produce olives this year but I fear it will soon run out of summer, so ripe olives are unlikely. Good to see it attempting to procreate though.

Another tree trying to fruit is a citrus called Yuzu, apparently this is grown in Japan where winters can be cold so perhaps ripe fruit in Scotland is possible.

A late sowing of New Zealand Spinach produced little plants which were set in a large Air-Pot in late July. By late August the plants had filled the pot and provided enough greenery for a good amount of spinach and made a paneer curry. It is continuing to grow fast and a week later is ready to pick again. This is a tender plant so it will be interesting to see how well it can grow into the cooler end of the season.
