Gardeners' Notes:

Started mine indoors early 2009. The plants never got mature enough to blossom. I thought they were only hardy to zone 6, so I was kind of disappointed that they would die over Winter. I left them anyway...and in the Spring 2010, about 2/3 of the plants survived. It took them awhile to perk up, kind of like my herbal sage plants. They had a nice bloom...a lot taller than I thought they would be. I do have the plants in a relatively protected area, so maybe I have a micro-climate. I'm going to try to keep them again, as they are really big and healthy.

Even gardening from 1 zone warmer (zone 6a in Connecticut and Philadelphia) than the given northern limit for this very fragrant flower (zone 5a), Wilson & Bell (The Fragrant Year) eventually gave up growing what we now call Erysimum cheiri outside. That plus the fact that this flower doesn't seem to be grown much outdoors here in zone 7, either, certainly makes me wonder - but then, all the more reason to experiment with wintersowing E. cheiri this winter and again indoors about 2 weeks before last frost (see below) so I can hustle any seedlings outdoors before damping-off fungus rears its fuzzy head. Wilson & Bell say that from North Carolina on south that 6 months of winter bloom can be obtained. Winter gardening must be heavenly down there.

Well, apparently, it ... read more

Lovely fragnance and bringing colour in the garden so early in the season. I 've started these from seeds last year and planted them out...stayed wintergreen. All parts of the plant are poisonous..specially the seeds. Plant contains Cheirotoxin that has similar but lesser toxic effects as Digitalis does...

Wallflowers are nice companion plants for spring bulbs. They bloom all through the daffodil and tulip season. I especially like the dark red blooms of the cultivar 'Blood Red' as they emerge from their black buds.


On Sep 28, 2004, smiln32 from Oklahoma City, OK (Zone 7a) wrote:

Sow seed outside, one fourth inch deep, in June or July. Seed can be sown outdoors up to 2 months before first frost. Seed germinates within a week when grown indoors at temperatures between 55 and 65 degrees. Seedlings are spaced 9 inches apart in the garden. Cuttings may be taken after the plants have bloomed. Most varieties have fragrant flowers. Some winter protection is needed in colder climates. Does not perform well during hot weather.

To grow as annuals,sow outdoors in early spring or indoors about 8 weeks before your last frost date. Plant seed 1/4 inch(6mm)deep. Set plants out 8-12inches(20-30cm)apart around the last frost date. In frost-free areas,grow wallflowers as biennials Sow seed in pots in a nursery bed in early summer;move plants to their flowering position in early fall. Water during dry spells to keep the soil evenly moist. Pull out plants when they have finished blooming.
