## The Horticulturist's Guide to Plants

Are you a wizard scavenging in the forest for spell components? Or perhaps a ranger searching for an herb that’ll help your injured halfling buddy? Maybe you’re just a druid looking for their next lunch.

In the D&D multiverse, there are bound to be countless magical plants that can be found on your adventures. In this horticultural guide, we’ll explore some ways to incorporate plants into your D&D campaign using homebrew and official rules!

### Why Use Plants?
Plants are the perfect worldbuilding piece to establish ground rules for certain lore and help players immerse themselves in the setting. Understanding the ways that civilizations grow and harvest their food, create medicine, and even enchant items through the use of plants can give players something concrete to grasp on to, which is important for roleplaying games where the world exists in the players’ minds.

Beyond providing a foundation for your setting, these ground rules can offer interesting plot hooks, useful expendable resources, and help players come up with creative solutions to problems.

### Homebrew Plants for Your Game
A “useful” plant very much depends on the context of the goal your players are trying to achieve. Poisonous plants aren’t what they'd be looking for when trying to make a salad, but these deadly plants can be just what your party may need when they’re trying to off a rival.

In the below table, you’ll find 20 homebrew plants and their effects, which you can use to flesh <br> out the flora of your campaign world. The plant’s inclusion in your game, necessary <br> preparations, and effects are entirely up to you as the DM. Consuming or <br> using any of the plants below is considered a Use an Object action.

##### Homebrewed Plants and Effects

|:---:|:----------|:----------|
| 1 | Nightshade | The key ingredient in the assassin’s blood poison.
| 2 | Silverthorn | When brewed under moonlight for 8 hours, this plant can create a potion that gives advantage on Constitution saving throws against lycanthropy that lasts for 24 hours.

### Finding and Identifying Plants

If your players are looking to gain the upper hand in combat, craft a magical item, or brew a potent potion, they might need to find a specific plant or herb (such as the ones listed in the Homebrewed Plants and Effects table).

Below are some suggested checks that may allow them to discover more about the flora they’re looking for based on their character’s strengths. Keep in mind, these aren’t official rules and you as the DM make the final call about which check is needed in certain scenarios.

* **Arcana:** Have they studied the magical properties of the plant in question?
* **Nature:** Do they understand which effects are achievable through the use of certain herbs?
* **Survival:** Do they have enough experience with certain plants and herbs to determine which one they need and how to safely harvest it?

If these checks come up fruitless or if the characters don’t have a good enough understanding of the area or effect they’re hoping to achieve, they may need to consult an expert. Depending on where they are, and the class they’re playing, they’ll have different resources to acquire the knowledge necessary to find the plant they’re looking for:

##### Gathering Plant Knowledge
| Location	| How to Acquire Information |
|:-|:-|
| Apothecary |	The more sensitive the information, the more they can expect to pay. (Acquire with gold.) |
| Library |	Hit the books to find the information they seek. (Research with Nature or Investigation.) |
| Nearby Druid Circle |	Appeal to their love of nature and desire for its protection. (Negotiate with Persuasion or a quest.) |
| Witch or Hag |	Make a dangerous bargain for the information. (Complete a quest or make a trade.) |
| Black Market |	This will cost them dearly but is useful when they need access to forbidden plants. (Acquire with Intimidation, Deception, or gold.) |

Okay, the characters now know what kind of plant they’re looking for and the general area it might be in. What next? Well, I hope they had the wherewithal to buy an *herbalism kit* while they were visiting the apothecary because it’s going to make things a lot easier.

#### Using an Herbalism Kit

If your players have proficiency with an *herbalism kit* and have one on hand, identifying plants and safely collecting their useful elements is much easier.

In the Tool Proficiencies section of Xanathar’s Guide to Everything, it’s stated that players can get advantage on checks associated with a certain area of expertise as long as they’re proficient with both the necessary tool and a skill that applies to the check.

Further on down the section, these related checks and added benefits are provided for the herbalism kit:

> ##### Herbalism Kit
> Proficiency with an herbalism kit allows you to identify plants and safely collect their useful elements.
><br>
>**Components.** An herbalism kit includes pouches to store herbs, clippers and leather gloves for collecting plants, a mortar and pestle, and several glass jars.
><br>
> **Identify Plants.** You can identify most plants with a quick inspection of their appearance and smell.
><br>
> **Arcana.** Your knowledge of the nature and uses of herbs can add insight to your magical studies that deal with plants and your attempts to identify potions.
><br>
> **Investigation.** When you inspect an area overgrown with plants, your proficiency can help you pick out details and clues that others might miss.
><br>
> **Medicine.** Your mastery of herbalism improves your ability to treat illnesses and wounds by augmenting your methods of care with medicinal plants.
><br>
> **Nature and Survival.** When you travel in the wild, your skill in herbalism makes it easier to identify plants and spot sources of food that others might overlook.
><br>

> | Identify poison         20 |

#### Finding and Gathering Plants Without an Herbalism Kit

If they didn’t happen to grab an *herbalism kit* before heading out into the wilderness, we can pull applicable skill checks and DCs from the Arcane Herbology Exam: Vegetation Identification in Strixhaven: A Curriculum of Chaos to give us an idea of the expected checks required:

> **Flora’s Arcane Properties.** Correctly selecting the properties of samples requires a successful DC 13 Intelligence (Nature) check.
><br>
> **Specimen Identification.** Recalling the correct names of flora with arcane uses based on sight, smell, and texture requires a successful DC 20 Wisdom (Survival) check.

So, while identifying plants is such a trivial task it doesn’t need a check with an herbalism kit, without one it requires distinct knowledge and a shrewd eye.

Likewise, you can conceivably collect samples without a DC as long as you have proficiency with an herbalism kit and have one on hand, but you’d need to succeed on a DC 13 Intelligence (Nature) check without one.

Ultimately, these checks and DCs are up to you as the DM and will shift based on the environment, the plant in question, and any other roadblocks that are present. Still, they’re a good baseline to understand what your players can do when it comes to attempting to find and harvest plants in D&D.

### Crafting With Plants

Your players have discovered the plant they're looking for based on its properties, gone to the apothecary to find where it's harvested, traversed the wilderness to find the plant, took the painstaking precautions to harvest it, and, finally, it is in their grasp. Great! What next?

Crafting can be tricky in D&D, as its efficiency as written is entirely dependent on the type of campaign you're running. If you're running a campaign that includes weeks or months of downtime, then the rules for crafting may work fine as is.

If, however, the event where your players are hoping to use their newly acquired plant to poison a corrupt noble is tomorrow night, you may need to come up with your own rules for crafting so they can fit your use case better. You could also use the expanded crafting rules in Xanathar's Guide to Everything, as it fleshes out rules for crafting potions of healing and other magic items, which could be applied to other potions or equipment your players are hoping to create.

One thing that I would suggest is, if a player goes to the lengths to find and harvest a specific plant for the item they're looking to craft, consider dropping the DC, cost, or even time required to complete their goal. For example, if one of my players discovered that liferoot was the key ingredient of a potion of healing and made a point to collect some, I would drop the 25 gp cost associated with crafting the potion.

Enjoy Your Foraging!
So, now you know what plants to include in your game, how your players can find them, and what they can do with them once they’ve got them! Please note that D&D Beyond is not responsible for any stings, scratches, or poisonous bites your players sustain when searching the forest for plants to harvest.
