Gardeners' Notes:

I love this plant. It's a tough, no care native that thrives on neglect. I have it planted in pure sand, no irrigation and in 8+ hours of sun each day-the hottest place in my yard.

It spread by seed and runners. To collect seeds, let them dry on the plants, put them in a large paper grocery bag, upside down, in the garage, let continue to dry until you can shake the seeds from the heads. Sow them immediately or store in a zip type bag and sow them later.

In the spring, early summer you can also cut the runner between a mautre plant and a new plant, dig up the entire plant and immediately put it in a pot with moist potting soil, keep moist until you see new growth, plant them in a sunny place, water in well and walk away-that's it, no muss no fuss.

In Osprey Fl (9B) they bloom mid October and if you have enough they become a sea of gold. All plants are the same height and flat headed and are absolutely beautiful.

They are also a late necter plant for bees, but are visited by a dozen or more other necter feeders. Some of these are predators of garden and lawn pests.

I'm starting a new bed with goldenrod, Solidago Sempervirens (ht 4to 6 ft.) in the center and yellow top on the outside. Both bloom at the same time and in a couple of years I'll have yellow, yellow, yellow-can't wait!
