Your plantborn nature strengthens your mind and reflexes. 

Your Wisdom score increases by 2.

Alternatively, you may choose Constitution instead of Dexterity when creating your character.

You can communicate simple ideas, emotions, and intentions with both plants and animals. You know the Speak with Animals and Speak with Plants spells. You can cast each spell once per long rest without material components. Wisdom is your spellcasting ability for these spells.

As an action, you wrap yourself in sprouting foliage. For 1 minute, you become invisible while motionless in natural vegetation. If you move, the invisibility ends, but you gain advantage on Stealth checks until the end of your turn. You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses on a long rest.

You have resistance to poison damage and advantage on saving throws against being poisoned. You do not need to eat food, though you must spend at least 1 hour each day in sunlight or among healthy plants to remain nourished.

Your body heals through the natural growth of living plant tissue. Whenever you roll Hit Dice to restore hit points during a short rest, you regain extra hit points equal to your Wisdom modifier (minimum of 1). Blossoms briefly bloom across your skin as you mend.

Your connection to the living earth sharpens your awareness. While you are standing on soil, roots, moss, or other natural ground, you gain tremorsense out to a range of 10 feet. This allows you to detect vibrations and movement through the earth, though you cannot sense creatures flying or otherwise not in contact with the ground.

You blend easily into natural surroundings. You gain proficiency in the Stealth skill. If you are already proficient in Stealth from another source, you instead gain expertise in the skill, doubling your proficiency bonus for Stealth checks.
