Product Details

Product Details

A native of Africa, Popcorn Cassia (Senna didymobotrya) is a highly ornamental legume that's terrific for adding a tropical flair to gardens and containers. It’s a vigorous, multibranched grower that can achieve the height of a shrub in a single season. Flower spikes made up of clusters of dramatic black buds open to golden flowers. Rub the foliage to release the scent of buttered popcorn, which inspired this plant’s name. Plant this conversation piece in the company of Cannas and Colocasias.

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Popcorn or No

Picked this plant from a grower, just as an amusement for my Grandchildren. Rubbing the leaves did leave a popcorn smell on my fingers, however, the scent evaporates or dissapates after a few minutes. I wonder if this is another genetic "thing". I cannot stand the smell of Cilantro, so have never used in my own cooking.

Great plant

I previously rated this 3 star since I could not detect any popcorn scent to the plant but my wife confirms there is definitely a buttered popcorn smell to the leaves. The plant grows great and blooms well.

No Fragrance

As a horticulturist, I'm familiar with the Popcorn Cassia, but was disappointed with this variety. It grows well and has plenty of popcorn like blooms. But there is no fragrance from this plant, especially the buttery popcorn fragrance I'm used to experiencing (California Polytechnic State University has a great variety in their horticulture department that both blooms and smells like fresh buttered popcorn).

I am so surprised to learn the foliage of your Cassia does not release the popcorn scent when rubbed, as the younger leaves especially are heavily scented. I will be contacting you directly via email regarding this.

Love this plant

This senna is a great plant for the Raleigh area, zone 7b. We grow it as an annual, so not hardy here.

Cassia grows best in full sun and moist, well-drained soil. Plants flourish in the heat and humidity of summer. Water regularly and use a balanced, water-soluble fertilizer (such as 20-20-20), mixed and applied as directed, to promote lush growth and flowering.

Cassia is generally pest free and deer resistant.
