It doesn't matter which Larix understock is used, both (L. decidua and L. kaempferi) are possible.
The color of the young wood of L. decidua is a grey/yellow and from the L. kaempferi is a brown/red.

Larix 'Little Boogie' is not the right name for this plant, it must be written as Larix kaempferi 'Little Boggle'.
I searched for 'Little Boogie' at Google and several nurseries offering this plant under this false name, what a mess!

Also it's desriped as a cultivar of Larix decidua which is not possible because it's young wood has the brown/red color which is typical for Larix keampferi.

As well as the difference in shoot colour, they can also be told by cones; straight scales in L. decidua, reflexed scales in L. kaempferi.

Note though that the two hybridise readily; the chances that the plant is the hybrid between them (L. ÃÂ marschlinsii) are quite high.
