Tricolor Crocus (Crocus sieberi ‘Tricolor’) is a remarkable bulbous perennial whose flowers display three beautifully contrasting bands of colour: violet at the tips, white through the centre, and golden yellow at the base. Beginning in February or March, the blooms open widely in the sunshine above fine, dark green foliage accented with a distinctive silvery stripe. Growing 10 to 15 cm (4 to 6 in) tall, this botanical variety creates a brilliant display from the first signs of spring. Hardy to Zone 3, it easily withstands Quebec winters and returns reliably each year when planted in well-drained soil.
Plant the bulbs from September through November, before the ground freezes, approximately 8 cm (3 in) deep and 5 to 8 cm (2 to 3 in) apart. Choose a location in full sun or light partial shade with light, fertile soil that remains fresh in spring and drains exceptionally well. Water lightly after planting, then only during unusually dry periods. After flowering, allow the foliage to yellow completely so the bulbs can replenish their energy reserves. A light application of compost in autumn or early spring is generally sufficient. Avoid heavy, waterlogged soils as well as excessive moisture during summer dormancy.
Tricolor Crocus is ideal for rock gardens, borders, naturalized lawns, beneath deciduous trees, and spring containers. Planted in generous groups, it naturalizes quickly and gradually forms an original carpet of vibrant flowers over the years. Pair it with snowdrops, grape hyacinths, scillas, and other small spring bulbs to create colourful, natural-looking displays. Its early flowers also provide valuable nectar and pollen for the first bees and other pollinating insects active during the first mild days of spring. The flowers are grown strictly for ornamental purposes and are not intended for consumption.
