Gardeners' Notes:


On May 14, 2016, Skiptonius from Medford, WI wrote:

I purchased a shade seed mix for the north side of my house which included Siberian Wallflower. Only a few things grew... After some research on the seed types in my mix I found that all of the seeds enjoy sun during the day but prefer shade during the hotter afternoon. I tried my seed mix the following year on the east side of my house and I was overjoyed! I received many compliments on my flowers and they reseed every year. Most of the flowers are pinks, purples, or blues, but I love the burst of color from Siberian Wallflower! I live in central Wisconsin, zone 4.

I got this in a wildflower seed mix. It didn't bloom the first year, but was one of the only plants from that mix that stuck around. It stayed green throughout winter, even being buried in snow and surviving several long freezing periods. In April it bloomed!

I got the usual bright orange, but I guess I was lucky, because I also got a few stalks of other colors: a dark red and orange variation, and some creamy yellow with reddish purplish markings.

I had planted these in a shady area but the stalks leaned out of the bed to reach more sun, so I collected the seeds off the dried stalks in August to sow in some sunnier areas.

Sowed outdoors in spring. Two months later you see showy, glowy, orange flowers that perfumes the whole garden. Even survived several hailstorms. I hope they will self seed. Would be nice to have them again year, after year.

I planted this from a "mixed" garden, just found the name today. Love the smell! It took 3 years (grown from seed) before it bloomed. If dead-headed will continue to bloom all summer until frost, evergreen even in ND. Grows in partial shade, never had to water, does well if ignored. I hope to collect seeds and plant elsewhere in other gardens.

Put a few of these hearty, glowy (love the brilliant orange!) plants along a sinuous "dry creekbed" we created from all the rock we've excavated during new bed preparation and they have continuously added to their own numbers. Their informal sprawl is exactly what we hoped for, their scent adds delight to the process of working around them and we have begun to collect their seed and sow it elsewhere in the yard to spread the cheer. Love 'em!

Beautiful plant, grows well here in Ontario. If kept dead headed will bloom all summer. Highly scented

Because I am trying to grow this in southern China, in a very clay based soil, I have had difficulties, but was able to grow them. The only problem, be careful, cats who like to eat plants maybe end up fairly sick from the leaves. I have had to deal with a lot of vomiting as a result of my cat ingesting them.

Flowers are Highly scented. Unfortunately I don't care much for orange flowers and mine bloomed orange. But the scent is wonderful!

An evergreen, hybrid, short lived perennial.

Has grey to deep green, slightly downy, lance like, toothed leaves. Bears scented, yellow to bright orange, 4 petalled flowers.

Flowers March - May

Loves a well drained, poorish, neutral to alkaline soil in sun or light shade.

Usually grown as a biennial.

May be subject to club root fungus (Plasmodiophora brassicae) especially in acid soils. Don't grow in a bed where you expect to grow cabbages in the next year or two (and vice versa), especially if you have bought the plants from a nursery.
