Name that Old Horror Movie?

Hello Movie Enthusiasts,

Looking for a horror B-movie from sometime between late 60s to the mid-70s, maybe to the late 70s, to the best of my knowledge. Can't remember if it was a theater movie or TV movie release. I remember seeing it on television, never saw it at the theater.

One of the scenes (think near the end) involves a women who is attack by a tree or plant with blood/fluid sucking branches after she walk out into a garden area of a house. The scene shows the branches attacking her being emptied of fluids leaving what looks like a dried up corpse afterwards. Think this tree/plant has several victims in the movie.

Thought it was the movie Frogs (1972) where all sorts of mutated creatures live on the island, but the plot doesn't mention the woman and blood sucking tree.

Thanks,
