Crocus grandiflorus
Easy & large
One moment there's nothing to be seen, the next your garden is full of colour and warmth! The large-flowered crocuses (Crocus grandiflorus) are very easy to look after. We love them. The crocuses have even more impact if they are planted in large swathes. Plant the tubers in the autumn. In well-drained soil. The flowers bloom in the spring.
The tubers can be planted in open ground or in a pot. Potted tubers aren't frost hardy, so bring the pot indoors or protect the plant with bubble wrap. Space the tubers out when planting in open ground. The distance between plants is three times the width of the tuber. Plant the tuber the depth of three times the tuber's height. Plant the tubers in full sun or partial shade. Water the tubers immediately after planting. Don't water it until the soil feels dry to the touch. The tubers come in organic packaging. Made of 100% natural materials and 100% recyclable!
All our flower bulbs have the Holland Selection A quality mark, and come with a 100% guarantee that they will grow and bloom. You can be certain that the flower bulbs will grow.

As soon as possible after receiving the Mammoth Crocus corms, they can be planted in the garden, flower pot or planter. Plant the small crocus corms in a planting hole that is three times as deep as the height of the corms. For example a corm of 2 cm should be planted in a 6 cm deep hole. The planting distance between the crocuses is about 3 cm. Loosen the soil well and plant the crocus with the little point facing upwards. Refill the planting hole and avoid walking over the soil. Plant the corms one by one with a small trowel or a special bulb planter. For larger areas, make a larger planting hole to accommodate several corms. Mammoth Crocuses grow best in loose, well-drained soil in a spot in full sun or partial shade. The more crocuses planted the more the effect this spring bloomer will have. Plant the crocus in groups of at least 25, or divide about 25 to 50 corms evenly over the garden border, flower bed or even over the lawn.

Mammoth crocuses in a pot

Mammoth Crocus grow well in a flower pot or patio container. Make sure you use fresh potting compost and put a layer of gravel or hydro granules at the bottom of the pot. Place the corms in a planting hole three times as deep as the height of the corm. For example a corm of 2 cm should be planted in a 6 cm deep hole. The planting distance in a pot is about 2 cm. To protect the small corms grown in a pot against frost, move the pot to a frost-free area or cover it with bubble wrap. Water during dry periods.


Easy to care forthe large-flowering crocus are ideal for naturalising and can be left in the same spot for years without requiring any care and attention. They will multiply and flower in abundance year after year. After flowering, leave the foliage to die down naturally and cut back when it has turned yellow. These crocus also look great planted in the lawn, but you can only mow in the spring after the leaves have turned yellow. The following spring, the large-flowering crocus will reward you once again with an abundance of colourful flowers.


Mammoth crocus provide extra-large flowers! This mix contains the most beautiful colours and varieties. The crocus is one of the first messengers of spring in the garden. The charming flowers cheer up your garden or patio early in spring. This low cormous plant flourishes even more wonderfully in a flower pot or planter. Our mix consists of white, yellow and purple crocus. A wonderful composition of colours for the early spring. Take a close look at the little heart to admire the thick yellow-orange stamens.
