Perennials from seed at this time of year

Im led to beleive the same so ive just put all the seeds in together..pick n mix x

 

I just sowed some Agastache aurantiacum seeds, I've planted them and I'll see what happens.. probably nothing, but they are half hardy perennials according to the pack. I think they're a little hardier than that though.

 

At the moment I have Penstemon heterophyllus "Blue Springs" just germinating. Nows as good a time as any I think - they have time to grow rapidly in the greenhouse before moving them to the coldframe in late August. They should then have enough of the "summer" left to continue to grow fairly well and acclimatise to coldframe conditions where they can live until the spring.

I also have some Arisaema triphyllum germinating - slow growing so they will need full protection this winter.

So I guess that my point is that there is no wrong time, but be aware of the aftercare requirements before jumping in too deeply.

 

I was thinking the same thing a few weeks back, so I sowed some Poppy Papaver, Mrs Bradshaw, Primula Vialii & some Cosmos, apart from the Poppies, all are hardy perennials, I had the view to overwinter them in the greenhouse or a cold frame.​

​

The Primula Vialii is slow and shows no life but all the rest have germinated, I am guessing that this will work or will their biological clock kick in and stop their growth?​
