Dwarf pea varieties make an attractive addition to a windowbox, with their colourful flowers and interesting tendrils, which allow the plant to scramble over the other plants you have growing. Don’t expect to get huge crops from your peas, as generally they need a good deep soil to do their best. Sow seed: 4-5cm deep, 13cm apart (Throughout year, depending on variety) Varieties: Kelvedon Wonder
An oriental brassica, popular in Chinese cookery, which can also be used as a crunchy addition to salads. An attractive plant that needs a deep, moisture-retentive soil with plenty of sun to do well. Sow seed: In pots 2cm deep at 20-25oC from mid spring to early summer. Transplant out, 10cm apart in mid summer. Varieties: Cantong White, Jok Choi
Parsnips prefer a sunny, open site, preferably in deep, light soil, although there are more stubby varieties that will do well in shallower soils. The roots are hardy and have a distinct flavour, making them a good crop for harvesting over winter. Sow seed: 2cm deep, in-situ, mid-late Spring, 10-20cm apart depending on variety Varieties: Cobham Improved Marrow, Tender & True, Javelin
Potatoes need a deep and fertile soil with lots of moisture and so are probably not worth considering for a windowbox, especially as harvesting will also involve major disruption to any other plants you have growing in it.
Pumpkin & Squash varieties need either support, such as a trellis to grow, or will sprawl too much, so I wouldn’t consider them suitable for a windowbox.
