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).
|A useful, drought-tolerant plant for late summer and early autumn colour, bearing dense plumes of tiny bright yellow flowers on erect stems a metre or more high. Can be invasive, so best cut hard back before the plants set seed.|
|Sowing and/or growing instructions|
|Best sown outside in autumn or very early spring, as germination is improved with winter chill. Sow on the surface of slightly gritty compost, covering with a sprinkling of compost or fine vermiculite. Provide the shelter of a cold frame, pricking out seedlings as they become large enough to handle, growing on and planting out when big enough.|
