Colchicum autumnale ‘The Giant’ is in full flower in our alpine rock garden this week. This widespread Central European species bursts out of the ground for us in mid-late October with a stunning show. The cultivar, ‘The Giant’ has abnormally Y-U-G-E flowers. Hardiness Zone 5a-8b.
The star of the fall garden this year has been Colchicum tenorii (recently corrected to Colchicum cilicicum), which has been flowering for weeks. Our clump of this Italian native bulb, began as a single bulb in 2000. Once the flowers finish next week, the large, green leaves will emerge and continue to grow through the winter, before finally going dormant in mid spring. This is growing in our full sun rock garden in a soil mix amended with Permatill. (Hardiness is Zone 4-8).
