Swingle Citrumelo

[Wahl]

Does anyone know if Swingle blooms are new growth or last years growth? The last 2 winter has been cold here going down to 0F and my Swingles have lost all the leaves and have not bloomed so was just wondering if it would or maybe just trying to stay alive.

I have 3 Swingle seedlings.  They always bloom on new spring growth. Often, they lose their leaves when winter temps drop into the low teens but they come out with shoots and flowers, a little later than normal.  I also have a Dunstan seedling that is less cold tolerant than the Swingle but it makes large attractive flowers on new growth.  Aside from trifoliate I can't think of a hybrid that blooms on old wood.

Mine does not seem to be putting blooms on. Maybe we got to cold.
