Daylilies are a diverse perennial great for Canadian gardens.
Here on the prairies, we have grown over 200 varieties
The "day" in daylilies. That is it, the flowers are open for a
day and then wither away. The key is to grow varieties with many
buds and scapes.
As the years go on hybridizers are making advances for Northern grown
daylilies. They are breeding for higher bud counts, opening
earlier,better branching, more cold -hardiness.
About The Cold
It is simple, some do better than others in different climates.
Keep in mind daylilies are also a perennial in Florida. This
means that there is a diverse genetic background in daylilies.
Some just prefer the south, some will grow in the north and the south
and some prefer the north. There is trial and error involved.
Daylilies that enjoy your garden's climate will bloom, come back year after year, and multiply.
Diploids and Tetraploids
There are two main categories of daylilies, diploids and
tetraploids. It is the number of chromosomes in the plant.
Both types are widely available. Sometimes tetraploids exhibit thicker
petals and leaves.
