Gardeners' Notes:


On Aug 24, 2017, janelp_lee from Toronto, ON (Zone 6a) wrote:

Biennial wildflower, non-native. Its summer to fall flowers attract bees and butterflies. Good for cut flower. Self seeded freely so it can be invasive. By deadheading and removing unwanted seedlings can keep them in control.

An incredibly hardy flower here in the alkaline clay soils of Zone 7. I've observed both yellow and white forms growing wild by the roadside in poor soil no more than 1/2 inch deep. This year it showed up in my horse pasture, possibly bird-planted. Very shallow rooted, transplants happily even when in bloom.

This is a very pretty little mullein that will grow all over the place if you let it. My information says that it is hardy in zones 4-9. It is definitely evergreen here in zone 5.

A biennial plant from Central and Southern Europe.

Has broadly lance shaped or oblong, deep green, wrinkled, toothed leaves borne in a rosette. Bears tall, slender spikes of yellow flowers with reddish-purple, hairy filaments all through summer, followed by reddish, round pods that are full of little seeds.

Flowers mainly June - September

Loves a well drained soil in sun and a slightly sheltered aspect due to their height. They even manage to reseed on our clay soil and survive the Southern English wet winters.

Very easy to please, long flowering and with seed pods that also add colour to the border.
