Botanical Origin

Your aroma wafts the air around you, and you feel at home in sunlight. Your skin may take on a rougher surface, and your veins may appear more green.

Blooming Buds

At 1st level, you can call forth vegetation as you access the floral power within you. Whenever you cast a spell of first level or higher, you can call forth vegetation that takes up a number of 5-foot squares equal to your proficiency bonus. The first of which must be within 5 feet of you, and each square after be within 5 feet of another square. The vegetation is difficult terrain, is two feet high and lasts for a number of rounds equal to your proficiency bonus.

As photosynthetic cells flow through your body, it causes physical traits of your botanical lineage to manifest. At 1st level, whenever you finish a long rest, you gain a number of temporary hit points equal to your proficiency bonus plus your sorcerer level.

Additionally, while you have temporary hit points, you also cannot be blinded or deafened.

You also gain proficiency with an herbalism kit. 

Brush Habitation

Starting at 6th level, whenever you are within reach of dense vegetation, you have advantage on checks made to hide, and can do so even while under direct observation.

In addition, you advantage on survival checks made to forage for food and you double your proficiency bonus with herbalism kits.

Brambleform

At 14th level, you gain the ability to surround yourself in thick thorny vines that protect you and retaliate against attackers.

As an action, you can cause thorny branches to surround you for 1 minute.

Your AC becomes 18, and cannot be reduced below 18, and as a reaction whenever a creature attacks you with a melee attack, you can cause the branches to deal piercing damage equal to 1d8 plus your charisma modifier.

Whenever you take fire damage, reduce the number of rounds this feature lasts by 1d4.

Once you use this feature, you can't do so again until you finish a long rest, or unless you spend 5 sorcery points to use it again.

One With the Wilderness

Beginning at 18th level, you have become mostly plant. You skin turns green, and flowers bloom from your body. You are still treated as a humanoid. You can no longer be blinded or deafened and any critical hit against you counts as a normal hit instead, even if you are incapacitated. You have a resistance to poison damage, but whenever you take fire damage, you also take 5 additional fire damage, reduced by your constitution modifier.

While in dense vegetation, you are always under the effects of a pass without trace spell.
