but all are worth growing. For descriptions and lists of

Digitalis : This is our old friend the Foxglove. It is 

 really a biennial, but will often go on for four years or 

 more. It comes up readily from seed sown in the spring 

 or in June in sandy soil, and the plants so raised flower 

 freely the following summer. Any good soil suits it, so 

 long as the position is not too sunny.
