GUAYUSA: A strong stimulant with a high percentage of caffeine (up to 2%).
Guayusa is possibly contains the highest percentage of caffeine of any plant. The leaves are often boiled for use more than one time because of this high caffeine content.

It is said that drinking Guayusa tea may produce lucid dreams (The state of dreaming where you are aware that you are dreaming). Some people refer to it as the “watchman’s plant” because a person can remain aware even while sleeping.

This is a large shrub or small tree from the Amazon rain forests of Ecuador. Also used as an ayahuasca additive and internal bodily cleanser (because of its emetic properties) by some shamans before ayahuasca use. Requires more warmth and humidity to grow than Ilex paraguariensis, a similarly employed species. Tropical and it grows very well in Central Mexico, either in the ground or in large pots.



MATE, PARAGUAYAN TEA, YERBA MATE: Mate is one of the most popular stimulating beverages in South America. Contains caffeine (up to 2%) and theobromine and is somewhat stronger than coffee or tea. Mate is a tonic, nervine, diuretic and stimulant.

Yerba Mate plant

A holly, this plant is often kept trimmed to shrub size and can be grown in a tub in northern climates and either in tubs or in the ground in subtropical or tropical situations. It survives temperatures down to about 25° f.

Give young plants some shade. Likes humidity and heat. Needs well-drained acid soil. It is evergreen and dioecious. Currently, we have only female plants. Female plants tend to be milder in flavor, and slightly lower in caffeine than the male.

Khat Seed PodsQAT, JÂT, CHAT, KHAT, ARABIAN TEA: Of all the plants listed for sale in this catalog, this is probably the most controversial (in legal terms). Although it is listed in a previous edition of The Sunset Garden Book as an ornamental, there are people in power in this world who think that the effects of chewing Khat are — how do I say this diplomatically — undesirable.

According to a grant sponsored by the United Nations Fund for Drug Abuse Control, the main subjective effects of Khat use are “euphoria, improved intellectual efficiency and alertness.” The active principles are norpseudoephedrine and cathinone. It is non addictive, but excessive use can produce some symptoms of amphetamine psychosis. A synthetic diet drug related to cathinone is phenylpropanolamine.

The “War on Khat” has already been entered by the US, most noticeably by the invasion of Somalia a few years ago, partially in an effort to gain control of the Khat trade. How the citizens of any country tolerate the illegalization of any plant I find mind-boggling. I can understand a society needing to have individual actions (murder, violence, theft, abuse, etc.) be illegal, but I can’t understand the prohibition of the cultivation and personal use of any plant, be it Khat, tobacco, opium, coca, pot, etc. Well, I mean I do understand the economic benefits of such prohibitions: A select few people become extremely wealthy off of illegal sales. But I don’t understand the acquiescence of the populace. It appears that drug laws are enacted to create criminals, not to remedy social problems.

To further digress: I once lived in what is termed “the emerald triangle,” three counties in Northern California that grow a large quantity of marijuana. In the summer it’s a war zone. The military and police are constantly overhead in helicopters, the Highway Patrol routinely stop anyone in profile, and police wander the hills trespassing and searching without warrant wherever they want. Civil rights are non-existent, all because some people are growing a plant which produces fewer deleterious effects than beer. Everyone knows of this abuse of power, but, I’m afraid, we also acquiesce. Oh,well.

Back to Khat. While the Muslim religion (predominant in the geographical area where Khat is used) bans alcohol and other drugs “harmful” to the body, it doesn’t ban Khat. The illegalization efforts that have been made in the past in this area have all been by the occupying colonial powers (the English and Italians).

To the Muslims, Khat is known as “the flower of paradise.” It grows easily to a large shrub or small tree in sub-tropical locations. Mature specimens I have observed have survived temperatures down to about 25º f. It is widely adaptable to different conditions and soils but seems to grow best in rich, moist, well-drained sandy soil in full sun (coastal) or light shade (inland). In its natural habitat, Yemen and Ethiopia, it grows to tree size on hill sides at about 6000′ elevation where it has a relatively stable temperature of 80º f. It is very easy to grow in Puerto Vallarta and the rest of the tropical world.

Normally the leaves are not harvested until the plant is 4-5 years old, after the plant matures and flowers. It is customary to drink coffee or sodas while chewing the young, tender leaves and stems. Sometimes bubble gun is chewed simultaneously (especially by Yemeni college students). The taste of Khat is somewhat astringent, especially if older, lower quality leaves are used. The effects (lasting from 2-3 hours) range from a mild increase in energy to a full-blown speed-like high, depending, of course on the quality and amount consumed.

Khat is rarely grown from seed in its native habitat because, as with most commercially grown drug plants, much effort has been made to develop higher quality strains. That being said, seeds are often the only method of propagation available to people living in restrictive areas.


Khat is relatively easy to grow in sub-tropical or tropical regions of the world. It is easy to grow in greenhouse conditions in temperate regions as long as the low temperature to which is is exposed remains above freezing. It is happiest at 80-90 degrees (f) or 28-32 degrees (C) but will survive and often even thrive at lower temperatures.

Germination is simple. Plant the seeds near the surface of any well-drained soil and keep them moist. In 1-2 weeks, they should begin growth. During the first year, they grow slowly, reaching only a foot or so in height. After the first year, they grow rapidly to large bush or small tree size and are ready for harvesting in 3-4 years. Pruning tips helps increase leaf and stem production. After the first year, these plants are heavy feeders and require frequent fertilization to maintain their rapid growth. Never let their soil dry completely.

Catha edulis will grow well in full sun or part shade. It’s ideal is 80 degrees (f) at about the 6000′ elevation in the tropics. This translates well to part shade, 80 degrees (f) at lower elevations.

Generally, the more red on the stems and veins of the leaves, the stronger the Khat is considered to be.
