The Dutch bulb growers talk about the ‘Double Tete’ when they mean the Daffodil Tete Bouclé. Logical, because Tete Bouclé is a double form of the common Narcissus Tete a Tete. A bulb of Tete a Tete spontaneously changed into one with double flowers instead of single ones. It happens more often that a bulb, out of the blue, changes into another shape or colour. In the plant world we call this a ‘sport’.
About the characteristics we can say less more than that they are exactly the same as Tete a Tete. She is an early bloomer, often together with the last Snowdrops, perennializes in garden like the best and is perfect on pots and in planters.
