Cannot instantiate a parameterized object inside of another class

I'm having troubles understanding the inner workings of classes and such.

I have a class called Attributes that contains parameters. In my .ino, I can simply instantiate an object with Attributes greenBark(1, 2); and everything is hunkey dorey.

Problem: Now I need to create a Attributes object in my other class, called Tree. I figured out if my constructor doesn't have parameters, I can create an object within another class just fine. However, my attributes class constructor has parameters. When I try to create an parameterized object within another class, the compiler tosses an error. How can I create an attributes object within my tree class? I'm sorry if I got some of these terms mixed up, I'm trying to keep up!

Here are my current files (made for this example:)

The .ino file

#include "attributes.h"
#include "tree.h"

Attributes greenBark(1, 2);

void setup()
{
  Serial.begin(9600);
}

void loop()

{
  greenBark.printAttributes();
}

attributes.cpp

#include "attributes.h"

Attributes::Attributes(int size, int texture)

{
  _size = size;
  _texture = texture;  
}

void Attributes::printAttributes()
{
  Serial.print("GreenBark Attributes: ");
  Serial.print("Size = ");
  Serial.print(_size);
  Serial.print(" Texure = ");
  Serial.print(_texture);
  Serial.println();
}

attributes.h

#pragma once
#include <Arduino.h>

class Attributes
{
  public:
    Attributes(int size, int texture); // constructor    
    void printAttributes(); // method

  private:
    int _size = 0;
    int _texture = 0;
};

tree.cpp

#include "attributes.h"
#include "tree.h"

Tree::Tree()
{

}

tree.h

#pragma once
#include <Arduino.h>
#include "attributes.h"

class Tree
{
  public:
    
    Tree(); // constructor
    
    void makeTree(); // method

    // I want to create an attributes class object in my current class, so naturally I'd try to
    // create the object just like I did in my .ino sketch, but the below line doesn't work.
    
    //Attributes redBark(1, 2);

  private:  
};

The error provided is this:
