When grown well, the Rusty Foxglove can grow up to 180cm tall, though usually it will make 90-150cm. It is best to plant this foxglove during late summer or early autumn so that it can produce strong flower spikes the following spring. The flowers of ‘Gelber Herold’ are yellow with strong interior rusty markings. There are up to a hundred on each stem. Happy in any sunny or lightly shaded spot which doesn’t dry out during hot periods.
NOT FOR TASMANIA.
