About the ionantha hand grenade
The ionantha hand grenade is a highly sought after form of ionantha. It comes from southern Mexico. Its stout, densely packed rosette gives it the blocky look that earned the name.
The plants we’re currently offering are XXL grade. They run 6-7 inches tall, noticeably larger than what’s typically pictured for this form.
Like other southern Mexico ionantha forms, it holds a dense coat of silver trichomes. It also blushes red as it approaches bloom.
Ionantha collectors specifically seek out this form. So it tends to sell to buyers who already know several other ionantha types and want the more unusual, blocky shape.
An XXL specimen at this scale makes a strong single-plant display piece. It’s not just another small ionantha for a bulk bin.
Add it next to a standard ionantha Guatemala or Mexico display. The difference in shape becomes obvious at a glance, which makes it an easy plant to sell as an upgrade.
Growing the ionantha hand grenade: Care Guide
Run it xeric, like every ionantha form we carry. Soak 10-14 days, then invert and shake dry.
- Water: Soak 10-14 days, then invert and shake dry.
- Light: High light with strong airflow; stronger light deepens the red blush.
- Feeding: Diluted TillyBoost Fertilizer monthly.
- Size: XXL grade, 6-7 inches tall; larger than the typical hand grenade you’ll see pictured.
- Form: Dense, blocky rosette; a distinct shape among ionantha forms.
Feed it TillyBoost Fertilizer on a regular cycle, compare it with our other ionantha Mexico form, or check the air plant care guide for xeric basics.
