Although Lavatera Mont Blanc is categorised as a hardy annual, I find that best results can be obtained if treated as a half hardy. To prevent the need for pricking out, sow just three seeds in individual small plant pots. Do this in early April and place them in the greenhouse, preferably unheated. The seeds will soon germinate and by mid May they should be ready to plant out in the garden border.
This very hardy plant will give an amazing show late June through till September. Although the foliage is nothing to speak of this is no problem as the pure white blooms smother the plant. Seeds can be collected in Autumn before disposing of the plants.
