Full of flower buds on each tip. Will be beautiful in about 2 weeks. NOTE I found about a dozen 2" sprouts in long pot so potted individual for selling later. This could be a big seller in summer & at Fall plant sale when they are bigger.
tabbycat On March 21, 2023 Miscellaneous Event
Plant is lush with so much new growth. On my patio by post for now. Today I cut about a dozen low sprouted new branches & put in water to see if they root . So far a few little plants have sprouted in big pot from seeds that fell. The long pot i put so many seeds in dont have recognizeable sprouts yet
