Why can't I buy Busy Lizzies (Impatiens walleriana) from Thompson & Morgan in 2012?


Information on Busy Lizzie problems from the Royal Horticultural Society.

Some of you may be aware of problems reported nationally concerning downy mildew disease (race 2 and 3) affecting the common Busy Lizzie (Impatiens walleriana). This is caused by an airborne fungus; it is worsened by humid conditions and plants can be specifically infected following a wet spring. Downy mildew symptoms on infected plants include yellowing leaves and a characteristic white fungal growth specifically on the undersides of the leaves. This is followed by leaf loss which eventually leaves just a mass of slimy stems, often with a tuft of yellow leaves at the tips. Plants will eventually die off.

There are no chemical downy mildew treatments or controls available at the present time to help, prevent or eradicate the problem. It is recommend that infected plants are disposed of, burnt or buried deeper than 50cm (20in). Affected areas should be rested from growing Impatiens walleriana for at least a year to avoid recontamination. This strain of downy mildew disease is specific to the common Busy Lizzie (Impatiens walleriana) only, so other bedding plants, including New Guinea Busy Lizzie types, can be grown without risk.


At Thompson & Morgan we want you, our customers, to get the very best from our plants in your garden this summer. With this in mind we have withdrawn the affected busy lizzies from our 2012 range due to the problems with downy mildew. We will review this again for 2013.
