Another Perennial plant I like to grow, are Delphiniums.

In March they are usually available as small plants at Garden Centres and is the best time to buy them at that stage. They eventually grow to between 5ft-6ft, in various shades of Pinks & Blues & White also. They need staking up with a cane and tied to it, as the stems can easily snap in windy conditions. They Flower in May/June and maybe later on in Summer, after the first flowers have died and been cut back, the new growth soon establishes.

Best grown near a fence or in a mixed border of Perennials.

You can save seeds from spent flower heads and sow a few seeds in a pot in summer, for flowering the next year.
