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.
Passion flower. Exotic flowers like these don't have to be limited to tropical gardens. A vigorous perennial vine that climbs via tendrils, the passion flower can be a conversation piece in the garden.
