Gardeners' Notes:

Positive mrhooney On Apr 12, 2010, mrhooney from Freeport, TX wrote:

I'm growing this plant in coastal Freeport TX in a protected greenhouse. It originally was planted outdoors, and bloomed sparsely if we had a warm winter (above 36 degrees.) I built the greenhouse around the established plant and it flourished. It needs slightly warmer winter temperatures, say around 45 degrees to really be happy. I'm sure warmer would be even better. This is it's second year of heavy bloom and I'd say it has over 50 trailing blooms. As each bloom drops, it leaves a large pea shaped orb. I don't know if it is it's seed. I'd be interested to know and may try planting some to verify.
