If planning to grow Clintonia from seed outdoors then fresh seed should be sown in the summer. Clintonia should be sown into flats that have been sank in the ground in a shady area and lightly covered. The flat should then be covered in glass. After two years of growth the seedlings should be transplanted.
If you plan to grow indoors first then they should be started at the end of winter. Seeds can take from between one to three months to germinate. Clintonia seedlings should be planted into a shady area in the autumn with a spacing of about 18 cm. ideally the soil should be rich and acidic.
Clintonia should be watered regularly during the summer months.
