Gardeners' Notes:

Neutral Weezingreens On Nov 9, 2002, Weezingreens from Seward, AK (Zone 3b) wrote:

Oxalis purpurea is summer dormant. For best blooming, strong winter sunlight is needed. This plant has large, clover-like leaves and funnel shaped 1-1/2" flower, usually pink, though there is a white blooming variety, as well.

Oxalis purpurea is often considered invasive, since it multiplies by bulb production, seeds, and runners. Grand Duchess has been said to be less inclined to be invasive. Oxalis purpurea was originally from The Cape of Good Hope in South Africa.
