Horticulture in the 1970’s:
The houseplant explosion of the ‘70s can also be attributed to the prevailing architectural and interior design trends of the time.

Houseplants: must have been owned and grown by the exhibitor for a minimum of six months.

Class 1: Houseplants grown for foliage.

First: Haworthia Zebra Cactus or Pearl Plant
Well grown cactus with with adequate moisture to provide for excellent color pattern and shape of leaves.  Consider a simple clay pot so as not to distract from the color/pattern of the plant.

Second: Begonia, ‘Paloma Prince’
Healthy coloration/pattern of leaves.  Turning more often would ensure more even growth and removal of yellowing leaves would improves horticulture.

Third: Crassula argentea ‘Jade Plant’

Well done on maturity… Possible lack of pinching/trimming has led to long arms of growth, discreet cutting back would improve overall growth.  The hanging section of the newer growth could be cut off, rooted and potted up for new plants.
