Extra bright, golden yellow blooms. Dutch Crocus ‘Mammoth’ is a showy beauty to herald the spring.
These dainty and delightful flowers are among the first of the spring blooms to open (or the last of winter, depending on where you live), unfurling just after the species Crocus and Galanthus.
Once established, these charming beauties can produce up to four flowers per bulb. Dutch Crocus blooms are the largest of the Crocus, and they are one of the easiest to grow.
Dutch Crocus grow best in cool to temperate climates. They look good in rockeries, beds and pots. Planting in a lawn beneath a deciduous tree will really create a wow factor. Thankfully the lawn does not grow very fast at that time of year and, because the foliage takes around five weeks to fade you shouldn't mow, but you will need to resist the urge to tidy! We mow a border around our patch which makes the whole thing appear like a feature as they fade.
Did you know, bees sometimes use Crocus flowers for over night stays? They bed down in the pollen rich flowers which close at dusk, and when they reopen at dawn, the pollen rich, well rested bee will emerge ready to start the day.
Choose a relatively sunny spot with well drained soil. Dutch Crocus will tolerate light shade, such as under deciduous trees, especially in more temperate zones, but the petals only open with sun so you will need some of that.
The bulbs don't need to be lifted every year; if they are protected from the hot summer sun, and have good drainage you can leave them in the ground, this is known as naturalising. If you allow them to naturalise like this, you will only have dig and divide them after four or five years. To protect the bulbs from summer sun you could add mulch, grow them in combination with perennials or beneath deciduous trees.
We advise you protect new growth from slugs and snails and to fertilise annually in winter and spring.
