<p>Double-flowered portulaca mix in colors hot pink, orange, yellow, and red. Hardy and drought-resistant flowers that close at night and on overcast days and open on clear days.</p><p>Plant seeds outside after the last frost when the temperature is at least 60 °F. As the seeds are super-tiny, it is better to mix them with fine sand. Plant into the soil worked in well-aged compost. Scatter them on the soil surface and cover with 1/8 inch of soil as they need light to germinate. Water with a misting bottle regularly until the plants are well-established. Thereafter you can lessen the watering. Thin plants to 12 inches apart.</p>
