The first flower to bloom in our garden this year. Several flowers per bulb, very showy. Will be planting more of these beauties!

I planted some from last year's spring container in the fall and they are blooming this year 2008. Lots of blooms for such small corms - didn't get full sun when in house but still blooms anyway!


On Aug 4, 2007, PhilsFlowers from Ocean Park, Surrey, BC (Zone 6b) wrote:

These little flowers are so welcome in mid-winter because they are the first bulbs to bloom and you know that no matter how cold it is, spring is not far away. Taking pictures of it is frustrating because the true color is never seen in the photo, you will have to grow your own to appreciate it. It is the palest and most delicate shade of blue there is.

My favorite color of Crocus! Beautiful! Love it, but so do Rabbits!

Wish the Wild Rabbits would stop eating my Crocus (leaves and flowers!).

A needed reminder that spring is on the way in Zone 5a/b. As of this posting I have not seen any flowers or buds yet, however the first few sunny, warm days will bring these little blooms out in no time. Easily grown here; very hardy; nice lawn ornamental. Color is almost pure white except the faint blue shades which must be closely observed to be seen.

A nice little early blooming cultivar. I think it needs to be in numbers for the subtle color to really have any effect. If added to a mixture, it assumes the appearance of white. There is a darker blueish spot at the tepel's outside base.

One of the first plants to emerge and often times doing so while there is still snow on the ground. Mason bees as well as introduced Italian honey bees are attracted to this plant as little else is in bloom at the time.

To the best of my knowledge, it is hardy down to zone 3a in that it can survive very cold winters down to -40F.

The plant is an introduced species to North America in that its native range is Southern Europe and Asia. Crocus have naturalized in some states so best to keep an eye on it.

It prefers well drained soils and requires high summer temps. It does not tolerate drought or high humidity. It doesn't attract any butterflies or hummingbirds BUT deer seem to really love it.

A Chrysanthus hybrid cultivar.

Bears slim, linear to lance shaped, mid-grey green leaves with a clear white stripe down the middle. Bears bowl shaped flowers with a yellow centre, the outside of the petals are a pale greyish blue, inside they are almost white.

Flowers between February to April

Loves a well drained soil in full sun. Dislikes waterlogged soils but grows ok on our clay soil. This one doesn't seem to multiply as well as the other cultivar Crocus we grow.

Won't come true from seed.
