Rudbeckia maxima seeds – (Coneflower)


This large and attractive plant will gain attention from the back of your border.  It has  handsome, blue-green leaves, and produces large yellow flowers  in mid summer . The yellow petals of the flowers surround a  large, almost black, centre cone. It is great  for cutting.


Rudbeckia Maxima forms a low clump  of large blue-grey leaves. From this low clump rise tall stems of yellow flowered daisies  which have large erect  black cones in the middle of them  in mid-summer. They are good for cutting. The basal leaves are spectacular, and the plant, being so handsome,  can be used as a specimen on its own, as well as being placed at the back of a border. In mild winter regions the lower leaves may remain evergreen. Clumps can  easily be  divided in early spring. Stems are self-supporting and seldom need to be staked. The flowers are attractive to butterflies. Deadhead regularly to extend flowering and encourage further blooms. Deadhead if you do not wish to self-seed.

The plant prefers a moist well-drained soil in full sun. Do not allow soil to dry out. Mulch if soil is prone to drying out. However once established the plant can tolerate a certain amount of drought, if it is well mulched.

Sowing advice

Sow indoors in late winter and spring and outdoors in spring. Sow seed onto moist well-drained seed mix. Just cover with a fine layer of vermiculite or mix. Propagate at 18-20°C. Keep soil moist but not wet. If there is no germination in 3-4 weeks, put the seed pot into a plastic bag together with a tag with date of entry, seal, and place in the door of the fridge for 2-4 weeks. Remove from fridge back to 18-20 deg for germination.
