I always thought it would be a Yew wand. I wrote an A/N about it that I will post here;

"It seems to be fandom consensus to think that Severus has an ebony wand, which makes sense since it’s a very dark wood type and it matches the movie’s description. (Ollivander probably uses wood stains to protect the wood though, so a wand colour may not be representative of the type of wood at all). However, wand woods carry different powers and meanings, and from all the descriptions I’ve read on Pottermore, yew made the most sense in Severus’s regard. (Also hawthorn and blackthorn, but I settled on yew).
[Ollivander] “Yew wands are among the rarer kinds, and their ideal matches are likewise unusual, and occasionally notorious. The wand of yew is reputed to endow its possessor with the power of life and death, which might, of course, be said of all wands; and yet yew retains a particularly dark and fearsome reputation in the spheres of duelling and all curses. However, it is untrue to say (as those unlearned in wandlore often do) that those who use yew wands are more likely to be attracted to the Dark Arts than another. The witch or wizard best suited to a yew wand might equally prove a fierce protector of others. Wands hewn from these most long-lived trees have been found in the possession of heroes quite as often as of villains. Where wizards have been buried with wands of yew, the wand generally sprouts into a tree guarding the dead owner’s grave. What is certain, in my experience, is that the yew wand never chooses either a mediocre or a timid owner.”
A yew wand is also wielded by Tom Riddle and Ginny Weasley. In Irish folklore, yew symbolises immortality, because it grows its branches down into the earth from which new trees grow encircling the original trunk. It also has a reputation as a death tree because every part of the tree, including the wood dust, is poisonous."

In the Kémya story I wrote it as a yew wand, 13" and with a phoenix feather core. I never really gave much thought to the flexibility though, but if I had to pick I'd say rigid.

I don't know much about wands or the lore behind them so whatever the authors go with. I have nothing against their choice.

My headcanon for Severus's wand is alder wood with a phoenix feather core. Flexible, length average at some 11-12 inches.

Black alder is a pioneer species, able to thrive where others can not and survive harsh conditions including pollution, though it is bound to be replaced by sturdier trees eventually.

And phoenix feather wands have a great range, which I think becomes Severus.
