PLEASE NOTE: Since plants are often sourced from the garden to order, sizes do vary a little, depending on how they come out of the ground, but I always endeavour to give a little more rather than less! They are sometimes shipped bare-rooted, but will approximate the size specified (e.g. a 9cm pot).

Light preference Full sun/part shade

Sowing time/depth Spring, barely cover
This magnificent, very tall - 2 metres or more - rudbeckia is a good choice for the back of the border. The large, bright yellow blooms have striking lime green cones and are borne on straight stems clothed in dark green foliage. A beautiful cut flower. Although my plants produce huge quantities of seed heads, none, in my experience, seem to develop seed that I am confident to offer - so only plants are available.

NOTE: Plants, when offered, may, depending on season, be trimmed right back and/or delivered bare-rooted, but will soon regenerate.

Sowing and/or growing instructions
This is not a fussy plant but, being very tall, is best placed to the back of the border and will require some support. I secure mine behind loose loops of string attached to wires stretched along the garden wall. Cut back to near ground level during the winter or early spring.

Seed (when available): Sow in early spring at 20C on the surface of moist, but not waterlogged, compost, covering with the barest dusting of compost or vermiculite, as light is required for germination. Pot on individually as germination occurs. The protection of a cold frame may be beneficial. Grow seedlings on until large enough to plant out. There is conflicting advice about whether or not cold stratification (giving the seeds a period of cold in the fridge) is recommended.
