Oxalis Versicolor (Candy Cane Sorrel) is a unique bulb with really spectacular flowers! Very beautiful in full bloom, they are even more stunning when they have not quite opened up completely and display a striking red and white striped pattern. They can be planted in the garden or in a planter on the patio or window-box. Store your oxalis frost free over the winter.
Borage - good companion plant for tomatoes, squash and strawberries and much-loved by bees. Flowers and young leaves are edible and have a mild cucumber flavour. Use flowers sparingly in salads and float in fruit punch / Pimms. Flowers can also be candied for cake decorating. More: http://theepicentre.com/spice/borage/
