The trees in the card are Hawthorns in full bloom, around early may, though sometimes earlier now!
However, ive been to the long man (once!) and from a view point I didnt see any hawthorn trees around, but great Ash trees so when I think of the 2 of Wands here I think that Ash, the energy of Nion (in the ogham) would have been more 'appropriate'. However Hawthorn (or the ogham hUathe) is here for a reason.
Hawthorn is a tree of pain for its thorns are sharp, though not septic like her dark sister the Blackthorn. Hawthorn is a tree of May, of Beltane and the fertility of the land. May Queens are often crowned with ivy and hawthorn blossom and these energies, of sex and fertility of hard work and pleasure I feel are part of this card.
There are the fires we burn out of necessity and the fires we burn for pleasure and I feel that the 2 of wands suggests that we need the two! We need to focus on our energy and support ourselves, which having the energy 'spare' to help and support others, our community and the wider world.
The idea of a dualistic energy of the physical realm and the Other are like that too. We need spiritual nourishment as well as physical nourishment too.
That theres no either or, but only together in harmony - for the greater good?
