Seed of the Week: Pereskiopsis Cactus

Our mystery fruit from last week were from an unusual cactus in the genus Pereskiopsis.

Pereskiopsis are unusual because they are cacti that have leaves.  They are like all other cacti in that they have glochids (tiny spines) and areoles.

pereskiopsis-flowerThe flowers are lovely, but short lived. In our yard they bloom in the afternoon and are gone the next day.

People who grow cacti often use pereskiopsis for root stock and graft other cacti to it. Because it is tropical in origin, the plants can withstand humidity and more frequent watering than other cacti.

One of our botany friends gave us this specimen and I’m not sure of the species. It is such an interesting plant, I’m not sure why more people don’t grow it.

Do you know what species this is? Have you ever grown a Pereskiopsis?

Mystery Seed of the Week 218

Today I don’t have any seeds to share, so I thought I would stump you with the fruit of a plant.

mystery-fruit-218-1Yes, those could have seeds inside.

mystery-fruit-218I should warn you that these are highly unusual plants.

Do you recognize what plant these fruit are from? If you choose to, please leave a comment with your ideas.

New mystery seeds and Seed of the Week answers are posted on Tuesdays.

Seed of the Week: Camelina

As Craig recognized, our mystery seeds from last week were from a camelina plant, Camelina sativa.

mystery-seeds-217These little seeds have been grown since ancient times as a source of oil for lamps. Originally from Europe, camelina is now grown throughout the world.

camelinaCamelina is an annual plant. It is generally grown in the summer in cooler climates, but can be grown in the winter in some areas with milder climates.

It has small yellow flowers like other members of the mustard family. The yellow flowers give it another common name:  “gold-of-pleasure.”

Camelina has been receiving some interest from researchers lately as a potential source of biodiesel and also as a source of oils human consumption. We are likely to be seeing more of it grown in the future.

Does camelina grow where you live?
