Planting young plants

From Early Summer TO Early Summer

Plant young plants in early summer in rich, moist soil and in a sheltered and partially shaded position. If growing as a perennial, winter protection will be required especially in cold, exposed positions.

 

Flowering Season

From Early Spring TO Mid Autumn

Small (1/4") flowers are produced in great numbers from early spring until the first frosts.

 

Propagating by seed

From Late Winter TO Late Spring

Sow the tiny seeds indoors about 10 weeks before the last frosts. Spread the seeds just on top of the compost and water thoroughly. Place them in a warm, well-lit area. The seedlings should germinate within a week or two, when you can start to thin them out. Once all danger of frost has passed, and the plants are at least 2" to 3" to 3 inches tall, transplant them to the garden—spacing about 4 to 6 inches apart. Alternatively, sow them straight in the soil outdoors after the last frosts.
