Purple Passion

Purple Passion is a unique asparagus variety for any asparagus enthusiast
either home gardener or commercial grower. Its special attractive purple
colour, flavour and tenderness distinguishes this variety from others. Our
field trial confirms all of these attributes with taste tests conducted
here. In addition, our trials indicate Purple Passion has productive yields.
For best performance, plant spacing for Purple Passion is 6-8 inches apart
in the row instead of the usual 12-inch spacing. When cooked, the bright
purple colour is reduced, but when served fresh in salads it provides a
colourful and flavourful accent. An excellent addition to any asparagus
planting.
