Queen Victoria is a moisture lover. I grow one in my.pool. I grow a purple flowered variety....name escapes me, well it's late, ....and again it likes moisture. Both varieties hardy with me....mild here...but they split very easily and make new plants quickly. Neither variety should be grown in dry soil...will simply whither away
Rudbekia Goldsturn, most popular perennial variety, also likes good nutritious soil. As with lobelia it is easily split to make new plants
In autumn or now, I split these plants, pot them up and plant out in early summer to flower later. If not regularly dug up and split the clumps die,out in the centre and spread
