Mirabilis Longiflora tuber = dormant till ??
Should I start to worry? I ordered a fragrant Mirabilis 'longiflora' (four o'clock) from an Ohio nursery about three weeks ago. It came as a dormant tuber in a 4-inch pot. The receipt noted that it it was still dormant. But now, after 3 weeks in warm, humid Houston - the pot shows no signs of life. I am keeping it slightly moist and protected from afternoon sun. Our daytime temps have been in the mid 70's.
When do these things break dormancy?
This is my first time trying the Longiflora variety. I have grown the 4'oclock 'jalapa' type from seed every year and have no trouble with them sprouting back from their tubers each year. They are the easiest plants. As usual, when I heard the 'longiflora' was more fragrant, I just had to get one. Hope it perks up soon.
