Many tulips in our range flower at different times; the really tough tulips like the dwarf Kaufmanniana and Greigii, see pink Heart's Delight and red and white striped Pinocchio, will break through the frosts of late February/March to reveal charming open flowers. Most of the standard Dutch-style tulips bloom in April (look out for those described as Single Early). Pure white Diana with her Purple Prince comes under this category and has shorter stems to withstand the worst weather in early April. About two weeks later. in mid-April, the Early Double tulips, with blowsy heavy heads and rich colours like Peach Blossom or precious Blue Diamond, will all be at their best. Their flowers last for a long time.
The Triumph or mid-season tulips come towards the end of April and are a cross between Single Early and Darwin tulips, boasting wonderful colours and are good for forcing. Taller Darwin tulips include the gorgeous Pink Impression which arrives in early May.
By mid-May you get the extraordinary Parrot tulips varieties plus the Viridfloras (look at Spring Green) which naturalises well. Around the same time you can also enjoy the Lily and Fringed varieties. With a season from March into June it pays to bear tulip flowering times in mind but this should never get in the way of planting them as they can all go into the ground - from the end of October into December.
