A variable species, but without question many of its so-called 

 varieties are due to crossing with S. Telephium. The plant, when

 green opposite leaves. Variation in the large series of garden forms 

 which I have examined is mostly in the direction of S. Telephium. 

 In my garden I grew for some years the purpureum form of S. Telephium, 

 which seeded freely and kept constant. Later I introduced typical 

 S. maximum, collected by the Baltic, near Danzig, where it also showed
