refers to a genus of several dozen
species of small clump-forming perennials
that have their origins in many
different Zone 3 regions from southern Europe to
China. They are most noted for being some of the very earliest spring
flowers. Crocus have since been cultivated
into a wide variety of hybrids, most developed in
Crocus are most impressive when planted en
masse. Pick out a large, sunny spot in the garden, the lawn or a wild area
such as a rocky slope. Plant large drifts using
groupings of 20-30 bulbs spaced about 8-10 cm apart. Crocus are ideal for this kind of naturalizing.
Many varieties will thrive and bloom for upwards of 20 years! In
the lawn, Crocus have perfect timing. They
will bloom well before grass starts to grow; by the time your lawn reaches
mowing height, the CrocuS are finished for the season. Established
Crocus clumps bloom earlier than first-year
plantings, so avoid planning your garden colours
around first-year bloom times.
Crocus are easy to grow! Plant yours in the
fall in large drifts anywhere you have sun to partial shade. Place bulbs
8-15 cm deep and space them about 8-10 cm apart. Crocus require almost no care and are hardy in
zones 4-8. If your Crocus perform poorly,
the most likely reason is overwatering in the
summer. Crocus prefer their soil damper in
the spring and fall, but dry and warm during the summer. Never plant Crocus near summer
annuals or other thirsty summer blooms. As you give the annuals the water
they need, you will be "drowning" the Crocus
and shortening their lives. Excellent companion
plants for Crocus include flowering quince,
forsythia, Asian jasmine and witch hazel.
