It's a bad idea to plant chrysocephalum until after the last frost when the weather gets warmer because they are not cold tolerant.

The earliest that you can plant chrysocephalum in Lincolnshire is April. However, you really should wait until May if you don't want to take any chances.

You probably don't want to wait any later than that or else your chrysocephalum may not have a chance to grow to maturity. If you are starting your chrysocephalum indoors then you might be able to get away with starting them a few weeks earlier.
