Growing Spartina Alterniflora: Suggestions/Contacts

Nov 13, 13 • Uncategorized • No Comments

Conversing with Joanie McLean of Mellow Marsh Farm in North Carolina unearthed the following…

Spartina Alterniflora is hard to grow from seed, and particularly hard to winter over. Seeds need to be watered and drained frequently to simulate the tide.  When watered, they must be fully saturated with water and then drained completely.

Because it’s hard to grow, Mellow Marsh Farm does not have the plugs in constant supply. They’re grown on demand.  When they used to have a buyer, they would grow from seed but had trouble wintering over the seeds and plants in a greenhouse environment.    (Even when plants go dormant in the winter, they still need the saturation/draining ritual to go on.)
The question of water and watering:

When growing, it’s ok to use fresh water and regular soil.  It’s only at the time when the plant needs to get ready to be placed on the shoreline/in water that brackish water is introduced.   Then, so as not to shock the plant, start adding salt water bit by bit to the draining ritual.

Who does grow Spartina Alterniflora?
Joanie  suggested contacting Stefan at American Native Plants in Maryland.  He collects seeds and grows it in huge amounts.  She also mentioned that he’s been involved in various different wacky projects and probably would be in to hearing about this one. He can be a resource for growing advice as well as supply of plugs.   Contact:  410-967-6353.

If we ever need Spartina Patens (high marsh grass), they have thousands of plugs ($.35 per plug) and lots of seed.   This is not the variety that would grow in/on the water, though it is salt tolerant and normally can sustain salt water inundation 3-4 times per year (rather than daily as is the case with Spartina Alterniflora). If we ever want to play with S. Patens we should let her know and she can hook us up.
