Lobularia maritima

Alyssums are a popular annual for use as an edging plant where lots of flowers are needed. Good for growing between walkway stones and as a filler between taller plants. 

They grow in full sun to partial shade in well-drained soils. During the summer, cut back plants to keep it flowering. Leave plants in the garden over the winter. In spring, remove plants to expose lots of self-sown seedlings. 

Popular cultivars include:

• 'Princess' Series
• 'Knight' Series
• 'Clear Crystal' Series
• 'Snow Crystals'
• 'Easter Bonnet' Series
• 'Giga White'
• 'Wonderland' Series

Pests and problems include environmental damage from drought or drowning or edema. They also may be affected by downy mildew, stem and crown rots or plants decline due to poorly drained soils. Very good soil drainage is a must if alyssum is to perform well in the garden.
