Non-hardy tazetta daffodils, these are the bulbs that can be put in a pot and forced without any cold period…in fact, they should NEVER be put in the refrigerator! If you can’t pot them up as soon as you receive them, store them in a warm, dry place like on top of the refrigerator; 16/17 cm unless otherwise noted; culturally, very easy to grow but their buds may ‘blast’ (never open) if subjected to a too hot and dry environment inside your home; the heights are variable, depending on number of ‘light hours’ given. The fewer hours of light, the taller they will be. (Best rooted at 55-65 degrees; then keep pots 65 degrees with bottom heat (70 degrees+) to ensure bloom).
