Rido,
No, the grandiflorums and arachnoideums flower first generally and then there's a bunch that bloom next, cantabricums and some marmoreums, and then the bulk of semps all in flurry.
If a plant is stressed they sometimes flower off season too.
Am glad you have some rollers too. They seem almost indestructible.
Sol,
Need to get a picture of my khaki semp as the huge clump actually looks great right now. It's probably more olive than khaki and unlike 'Olivette' it;s not a rotter or miffy grower. In fact it's a bit of a weed.
